Hi Fernando,

Baader Planetarium does not participate in this group and apparently no one
on the group has an answer to your question.  I recommend you contact Baader
directly via their web site.

Hi,
I have a Canon 5D MarkII without IR filter (was remove for my), at this
moment it has mounted your ACF-3 filter, I see that there is a new filter,
call BCF, specific for 5D MkII model, ¿can say you to me that
differentiates between both filters has?¿works bad the ACF-3 in 5D MkII
model?, its aid is very valuable for my, I am not safe if ACF-3 works well
with 5D MkII model, the color does not finish to me convincing, I see the
chromatic variety it very poor.... I am confused this yet...

Best Regard from Spain.

I have been waiting for three months for my Baader 1.25 Ha filter from Anacortes
also.

Hi everyone, new to the group here. I'm planning on getting an Ha filter for my
OSC camera (Orion Starshoot Pro DSCI) and am curious if anyone has any
experience with the 35nm Ha filter? Supposedly it is geared for interline
sensors.
Or should I just go for the 7nm Ha. any thoughts would be appreciated.

Thanks,
Mike

Hi all,

Just got my 10mm(?) Hyperion.  Haven't tried it yet as it's darn cold outside.

I was hoping to purchase several Hyperions to use as both 1.25 and 2 inch
eyepieces.  In looking at the Baader chart for the Hyperions, it looks to me
like if you remove the 1.25 inch barrel from the Hyperions (all but the
largest), that the remaining 2 inch eyepieces ALL have about the same focal
length, which is about 21mm.  Huh?  How could that be?  If all the differences
in the focal length properties are in the 1.25 inch barrel extension, then why
not just have different 1.25 barrels and a single lens.

Perhaps I'm not reading the Baader chart correctly.  I'm hoping someone on this
list could give some insight.

Hi Folks I'm new to this group and moving into narrow band imaging. I just
recieved a SII filter unmounted and am not sure which side goes toward the the
CCD sensor. The filter is gold colored on one side and lavander on the other.
Also does the OIII filter care which way it Is mounted?    HELP!!!   Jerry

Hi Larry,

To use the Hyperion eyepieces as 2" eyepieces you do not generally remove the
1.25" nosepiece with its included lens grouping.  Rather you just insert the
entire thing into the 2" holder, using care that the 1.25" barrel doesn't make
contact with the diagonal mirror (if using a diagonal).

As far as differences between the lenses in the main body of the various
eyepieces, though they produce similar focal lengths with the 1.25" nosepiece
removed, they do not have the same configuration inside the main body as they
are optimized for the various final focal lengths.

Final note about removing the 1.25" nosepiece - this is useful for the purpose
of inserting the available "fine tuning rings" and changing the focal length
(higher) or for using the eyepiece at a lower focal length though the edge
performance suffers noticeably.

Hi All, FYI, The golden side of the SII filter goes towards the telescope as per

Hi Group
Can someone tell me the weight of the Baader Herschel Wedge - please.

Reason is - I've just received my Borg 77 travel scope to be used on the night
sky and along with my Coronado SM40 / BF10 on the sun.

My next purchase will be a Herschel Wedge, my preference is to get the Baader
visual version, but perhaps the weight will be too much to balance the scope
effectively.

Thanks in advance
Best Regards
Carl

Hi Carl,

I can't find that spec in any of the online info and don't own one, but I
bet Alpine Astro can tell you: http://www.alpineastro.com

Also, as a point of comparison, the 2" Clicklock diagonal weighs in at 17.5
ounce (495g) so I would expect the Herschel Wedge is a few ounces more.

Hi everyone!
I just bought a SV102ED2 4" refractor and have also acquired, for my eyepieces,
Hyperions 21mm, 13mm and 5mm. I'm just waiting for the right mounting plate to
arrive in the mail before I can start using the setup. Hmm.. I do have a 2"
diagonal and I just realised that I should try to attach the EPs to it to ensure
that the barrel doesn't touch the diagonal.

Annyway, I do have some questions! :) I'm sorry if these have already been
answered.

Q. I like the idea of fine-tuning rings although I have yet to purchase the two
rings. May I know if using the fine-tuning rings affects image quality at all?
(Also... anyone selling their fine-tuning rings by chance?) :)

Q. I would like to (eventually) attach my APS-C DSLR (Pentax K-7) to my
telescope to take photographs, either long exposures or stacked short exposures.
Looking at the Baader eyepieces information, it looks like I have some options:
I can attach my camera (without a lens) directly to my diagonal (without an
eyepiece), I can attach my camera (without a lens) to the output of a Hyperion
eyepiece, or I can attach my camera (with lens) to the output of a Hyperion
eyepiece. May I know what method produces better images? Are there circumstances
where one method may be preferred over another?

Thanks! :)

Hello,

The slight change in lens distances imparted by the fine-tuning rings should
not affect image quality much, if any.  During visual use, I have not
noticed any degradation.

Regarding methods of astrophotography, here is the summarization I included
in my book, The NexStar User's Guide:

"Afocal.  With the afocal method, a camera, with its lens in place, is mated
to the eyepiece of the telescope.  This is the best (in most cases only)
method suitable for digital cameras, video camcorders, and standard web
cams.  In fact, afocal astrophotography was seldom practiced until digital
cameras became widely available.  It is possible to simply hold the camera
up to the eyepiece, but much better results are possible with special
adapters to hold the camera securely to the eyepiece.  The most critical key
to good afocal imaging is positioning the lenses of the camera very closely
to the first lens of the eyepiece.  Indeed, they should almost touch.  To
insure such close positioning, the proper eyepiece and mounting adapter must
be carefully selected.

Prime Focus.  When imaging at prime focus, the camera lens is removed and
the camera is mounted directly in place of the telescope eyepiece.  The
telescope becomes the camera's lens.  This method is commonly used with 35mm
SLR cameras, CCD cameras, and video cameras designed for astronomy.  Since
the camera is placed where the eyepiece is normally located, it is common to
use a "flip mirror" or off-axis guider to allow both a camera and an
eyepiece to be used.  The diagonal is replaced with the flip mirror or
guider.  The camera is mounted at the rear and an eyepiece is mounted in the
tube coming straight up from the side of the flip mirror or guider.  If
using an off-axis guider, after the image is centered, an autoguider will
often be used in place of the eyepiece.

Due to relatively long exposure times, prime focus astrophotography requires
very accurate tracking.  Long exposures also require polar alignment on a
wedge and guiding (manual or auto) is generally needed.

Eyepiece Projection.  While prime focus astrophotography produces stunning
images of extended objects, the added magnification required for smaller
subjects, such as the planets and close-ups of the Moon, is provided with
the eyepiece projection technique.  Eyepiece projection is similar to afocal
except the lens is removed from the camera and the camera is mounted above
the telescope's eyepiece.  Just as with visual observation, different
eyepieces can be used to vary magnification.  Eyepiece projection places
even more severe demands on tracking and guiding than prime focus
photography."

I'll also add here that with the advent of digital SLRs and web cam imaging,
the prime focus can now be used with much shorter exposures and guiding is
no longer a strict necessity.  Also, with the advent of eyepieces like the
Hyperion and their ability to directly mount a camera (with lens) directly
to the eyepiece, the afocal is much more common than eyepiece projection for
high magnification work.

New to the group but looking for an explanation as to teh real differences
between these two diagonals.  I can really tell by just reading the
descriptions, excluding the obvious nosepiece and clicklock on that diagonal. 
Any input appreciated!

Thanks Michael,

I had read both reviews but thought that I might have been missing something. 
From the reviews I conclude that it is the mirror coating that is the technical
difference.

Yes, the mirror is coated with different methods in these two diagonals.
The Maxbright mirror is technically better, but the Clicklock mirror is very
close in quality and substantially less expensive.

Hi guys, new to the group. I have a phenomenal Orion 110ED, and a Celestron
C9.25. I use a Celestron CGEM mount in a backyard observatory. I do almost all
imaging with a Canon 500D. I can't say enough about the 2" click lock visual
back (for the 9.25)  and 2" click lock diagonal. No fumbling with thumbscrews,
and a tight hold. I also bought the 8-24mm Hyperion zoom for visual work (not
too often these days). I just ordered the fringe killer for use with the 110ED.
This is a VERY sharp scope, so I'm hoping that the fringe killer will give it
that "little extra". Anyone having experience with this combo, please post. I've
obtained all of the Baader stuff from Agena Astro (agenaastro.com) who's
customer service is excellent. They ship fast, and I get my items within 2-3
days (CA to Ohio!). I have no monetary interest in them, they are just great to
deal with. I may want the M&S down the road as well. I also use a Burgess CX4
contrast filter, and wonder how it will stack with the fringe killer. Sorry for
the lengthy post, just wanted to touch base. I'll post a few images soon.

Thanks,
Bill

Hello all,

I'm new to this group and I have a Baader question that I hope someone can help
me with. I just purchased a Burgess 1278 5" f/8 refractor. I also puchased a
Fringe Killer filter but the person I baught it from sent me a Contrast booster
filter (He thought they were the same filter). My question is should I return
the Contrst Booster filter and buy a Fringe Killer or will the Contrast filter
do close to the same thing? I'm just looking to reduce false color with Lunar
and Planetary observing. Any advice???

Thanks,

Marshall

Hi Marshall,

The Contrast-Booster is basically the Fringe-Killer plus some additional
targeted wavelength blocking to improve contrast on most solar system objects
(the ones you would want minus-violet for anyway).  It does block more light
though and results in a slightly yellowish image.

More on the two filters here:
http://www.alpineastro.com/filters/filters.htm
The Fringe-Killer info explains the differences between the two.

Bottom line, if you like the looks you are getting of Jupiter right now, I would
say keep it.

Marshall,

I have the 2" fringe killer, and I really like it. I use it on my 110ED with
good results all around. I had to create a preset in Lightroom to take the
slight yellow cast out of my images of deep sky objects. For Lunar and
Planetary, it's really nice. Baader suggests stacking the fringe killer with the
Moon & Skyglow filter. I haven't used the contrast booster, but am sure it's
still a good filter to keep in the "toolbox". I think I'm going to get the Moon
& Skyglow next.
With that said, I'd probably go for the fringe killer. You can see the images I
took of comet Garradd using the fringe killer (after processing) here:

http://www.neoimagers.com

Hope this helps,

Bill

booster filter (He thought they were the same filter). My question is should I
return the Contrst Booster filter and buy a Fringe Killer or will the Contrast
filter do close to the same thing? I'm just looking to reduce false color with
Lunar and Planetary observing. Any advice???

Thanks for the follow-up, guys.

One of the websites I saw said that the Contrast-booster works better with
refractors 5" and larger and the Fringe-Killer for smaller achros. Think I'll
tru the CB filter with my 5"f/8 Burgess and I'll give a follow-up report in a
few weeks.

Again - Thanks,

Marshall

Hi guys,

The Contrast-Booster is actually a filter with the coatings of both the
Fringe-Killer and the Moon & Skyglow filter combined.  So, you get
minus-violet correction for achromatic refractors plus improved contrast on
solar system objects.

The fact that the C-B blocks more light is why some would recommend only
using F-K with smaller refractors.  And, the C-B has a more pronounced
yellow tinge so photographic use would require additional image correction.

For visual use, the C-B or the F-K coupled with the M&S really brings out
significantly more detail on solar system objects.  The F-K or the M&S by
themselves also improve detail in an achro refractor, though for different
reasons - reducing false color for the F-K, tailoring the light curve and
moderate violet filtering for the M&S.  In fact, I generally use the M&S on
solar system objects even in my 11" SCT which has no chromatic aberration
issues - it improves contrast on solar system objects in any scope.

Marshall,

I have the 2" fringe killer, and I really like it. I use it on my 110ED with
good results all around. I had to create a preset in Lightroom to take the
slight yellow cast out of my images of deep sky objects. For Lunar and
Planetary, it's really nice. Baader suggests stacking the fringe killer with
the Moon & Skyglow filter. I haven't used the contrast booster, but am sure

With that said, I'd probably go for the fringe killer. You can see the

Hello all

I'm also fishing around for info on what choice to make - F-K or C-B (2")
I have a 120mm f/8.3 Skywatcher refractor and at high powers the magenta 'glow'
is rather annoying for my eyes/brain; also at longer exposurea using a DSLR in
prime focus it's still a drag around brighter stars - luckily the RAW software
allows for some axial CA correction that works pretty well, but it would be nice
to reduce it before capture.
What would you recommend from those 2 (only one filter)? :)
Thanks.

Hello,

I'd recommend the Fringe-Killer.  The C-B will make the images a little less
bright and yellowish in tint so for your 120mm refractor with imaging in
mind, the F-K makes more sense.

I am hoping to use my Mallincam video camera to display the solar disk during
the Venus transit in June. My club will be hosting a public viewing and I'd like
to be able to show a live video view as the public queue to look through a
scope.

The Mallincam has a focal reducer attached to allow a full disk to be displayed,
the camera is then inserted all the way into the standard Clicklock adapter. I
have been having trouble getting the camera to come to focus, I am racked all
the way in. The scope is a Skywatcher ED80 with a WO focuser. I wonder if anyone
might have any suggestions that could help me out here?

Thanks

Michael

Hi Michael,

Try a Barlow between the Mallincam and the Herschel wedge.  If that doesn't
work, AT YOUR OWN RISK, try the Barlow in front of the wedge.  Take it out
after a very quick test to see if the Barlow is getting warm due to the
solar radiation.  I don't think that it will, but the potential is there.
