If you are only 8 km north of Brisbane CBD then you cannot be living far from me (Everton Hills).

I would be interested in what guiding software you are using with the GSTAR. I recently purchased a GSTAR and one of the roles I want to be able to use it in is autoguiding.

Hi all

Well finally I'm geared up with some extra aperture and looking forward to some
deeper images and mainly planetary portraits.

I've had the Black Diamond 12 sitting here for 3 months awaiting the new NEQ6
wide head to arrive. Just set it up last night. What a beast!
Very well packed and took only 5 mins to collimate after fitting the primary
mirror visual and laser. Definitely is critical when it comes to collimation but
really glad at how the NEQ6 mount manages to ride the tube fairly effortlessly
when blanced well. Yes Mike.. you were correct!

It's pretty hot and humid up here in the north so a little unfair on the optical
test but very impressed with the just post sunset views of the Moon and Jupiter.
I only wish I had the mount 4 months ago when promised so I could take advantage
of Jupiter at a better vantage point. Ah well..Mars is creeping into the night
sky.

Cheers
Steve

Thank Derek

Yes, the program has come along way. It certainly has many impovements and minor
bugs sorted. It's a real passion of development for both Chris and I - just hope
others are getting some real value from it. There are many new features we're
both discussing for a later version.

Cheers
Steve

Hi Darrin,

Yes, long time no hear is right. Been very busy at home and work has really
screwed us down through the GFC, just no time for astro work or just too tired.
Anyway, light at the end of the tunnel (excuse the pun) and I will be getting
back into it soon.

I feel your pain about bloody light pollution. Our reasonably darkish sky out
our way is just about gone. I have been on the war path to NSW planning etc but
bloody typically they don't reply. Will have to escalate further.

ps., "the wrath of Darrin's tougue", no way, I couldn't even imagine that being
a problem (lol)

cheers
Michael.

All you really need is the basic GSTAR b&w camera and the prostar 0.5  focal
reducer although your focal reducers may work quite well.I use my gstar
primarily for live view through a 10"sct and a panasonic widescreen crt tv.My
targets are the faint fuzzies that cannot be resolved with the eyepiece .As for
all the technical stuff I'll leave that to the experts.As for what's possble
wit5h this camera just see the photo gallery.I routinely have live view
comparable to what is pictured in "THE DEEP SKY OBSERVERS GUIDE" through scopes
of almost double aperture.Hope this helps.

g'day Charles,
  You've virtually already got everything you need.  The GSTAR is just a camera. 
Field of view that it captures depends entirely on what you attach it to. Attach
it to your SCT and it's a rather small FOV,  but use a camera lens attached via
an appropriate adapter and you can get several degrees of sky.  Use a CCTV lens
and you can get even more.
The whole thing depends on focal length and aperture.  Your guide scope will
produce a good field of view for a lot of targets while you guide with the SCT. 
An example would be my set up.  I have an ED80mm f6 guide scope with a 8"LX90
f10 SCT.  If I image with the 8" and guide with the 80mm,  I can just get the
Key hole nebula in the image,  but if I reverse and image with the ed80 and
guide with the 8"SCT,  then I can get the whole of the Eta Carina nebula.
There's a few programs that will give you field of view size by entering your
scope size and camera used.
  I reckon all the extras you might want would be a focal reducer and a barlow
lens.  By mixing and matching with your gear you should be able to image just
about most targets.

Good luck and clear skies
Stephen

Thats a fantastic image Darrin, well done.
I have lost motivation as of late but that has inspired me.
I hear with the local lights. Some units over the back fence were renovated
recently and they installed the worlds brightest flouro lighting in the driveway
that are on all night. I can read a book in my backyard at midnight now :-(

Hi Michael,

Long time no hear! With regard to the local lighting, no such luck there. The
direct neighbours have started to learn about their headlights though. The wrath
of Darrin's tongue knows no bounds.....  Seriously though, the image is the
result of good narrow band filters.

G'day Darrin,

site.  It'll be placed in an album of it's own with your name on it. A great

Darrin,

Absolutely awesome!!

I haven't a clue how you do the processing, but if you're willing to write a
how-to guide I've got my cheque book ready!

Neil

G'day Darrin,
AWSOME!!!  That's an incredible image mate. The colour and detail have got to be
the best I have ever seen.
I would assume we will see that image showing up in many magazines and APOD
areas?
Very well done and an inspiration to us all.

Hi Dave,

Thanks for the kind remarks.

Darrin

Hi Darrin
Yet again another very nice image and credit to your processing skills.If I can
suggest to the members who have a look at Darrins image instead of viewing from
the new images link go to Darrin's album and have a look at it as the original
to see it in all its beauty.

Cheers
Dave

G'day guys,
  just posted some pix of my camera finderscope.

http://tinyurl.com/yfbk9m6

  I used an old 9mm eye piece,  removed the lenses and then araldited a bolt into
the hole.
This was then screwed into the tripod base hole of a slow motion module.
The whole set up was then put into the top eye piece holder of the ETX125.  I
put a 125mm telephoto camera lens into the c mount of a CCTV camera,  soon to be
my GSTAR-EX CLR, and then I can either use it to find what I'm looking for to
image through the ETX or guide with the ETX and image through the GSTAR on top.

It works in the warm room but as soon as the weather gods stop stuffing around
I'll give it a real test.

Hi Guys,

I've just complete another coloured multi field image, this time of NGC7331 and
Stephan's Quintet.

This image was 6 panela acquired with an 8" f4 reflector from my balcony in
North Strathfield, Sydney. Each panel was compiled from 500 frames of Lumicon Ha
and 500 dichroic blue. Green was simulated and the Ha was also used as a
luminance channel. The key galaxies were imaged under dark skies with a 10" f5
reflector. Total imaging took about 7 hours. The approximate field of view in
the end image is 53 x 41 arc minutes.

The image can be found in my album.

Darrin

G'day guys,
  I finally did my first vid with Gstar software. My Gstar camera has
a minor glitch that Steve is looking at but I was hanging out to try it all and
found my old b/w security camera combined with a 135mm camera lens,   works just
perfectly.
It was a shot of the inside of the warm room but I had a good play with the
controls and this cam config may work quite well as a lunar live imager or a
finder scope.
I might give it a test run tonight,  weather permitting,  but the main thing is
I've started  :P

Stephen

Hi Jack

Thanks for your offer, I have reinstalled Maxim DL 5 and updated it. It now recognises the Belkin USB Capture on the guide without locking up. I am also able to move the mount using Cartes du Ciel and a cable to the handpiece so nothing is technically wrong now.

I have joined the EQMOD group and loaded the software but have not used it for guiding yet. I will have to purchase the cable suggested by another member.

Regards
David Rawnsley

I have tried Guidedog and Maxim with little success. I feel that the cable I am using from the lap top USB 2 port to the input of the HEQ5 guiding port may not be correct. Does any one know where I can buy an off the shelf cable.
