Hi all, at first i wish everyone here a safe and Happy NewYear. motivated by this Hubble movie: http://www.seds.org/messier/Pics/Hi-res/m1crabmov.mpg i wonder...
Hi Steve, I think that even with the diagonal, you are going to have trouble with the camera hitting the base when the scope points up at 90 degrees. In that...
Where can I get the very best (read simple) on-line explanation of Focal Reducers? I've got this bad feeling that I'm going to need at least a little...
http://us.f368.mail.yahoo.com/dc/launch?action=welcome&YY=1000745391&.rand=8dflsc4e2vs41 This covers both focal reducers and barlows (which are the opposite of...
Hi Duncan, It is called coma. As Kel stated in his response, this could be caused by too much distance between the focal reducer and the chip. If you are using...
Man, that 16" RCX400 sure looks good! (Dream on Buddy!) Yep, another big moon on the way. This is when I start doing narrow band imaging and some of the...
Hi Kel, It looks like coma on the bright stars. Lets hope tonight I will be able to perform more tests, using the sturdy 2'' extension tube and bringing the...
Thank you Steve! I was surprised to see it come out that well given the coma problems on the bright stars. Regards, Nick 40 00' 00' N 82 52' 47'' W ... From:...
Hi, Wolfgang - happy new year! Interesting animation - I don't recall seeing this done by an amateur before. I recall a thread by Matt Taylor on this very...
Hi, Buddy - Nice job on "The Eyes". This composition looks like a Happy Face :-) It sure is good to see galaxy season returning... ChuckR ... galaxies....
Hi all, Here is an image I captured of the open cluster NGC 1857 in Auriga. The atmospherics were terrible with the jet stream overhead and a great deal of...
Hi Steve, Buddy makes a good point here. I didn't think about it at first, but since my LX90 has a pretty short fork setup, my camera hits the base when I have...
Thanks Kel and Buddy, I screw the Atik focal reducer right into the nosepiece of the DSI-C. I can't get it any closer unless there is a shorter nosepiece to...
Hi Buddy, Nice image. I would love to image this area of the sky someday. Nick 40 00' 00' N 82 52' 47'' W ... From: Theron W Miller Jr <twmiller123@...> ...
Hi Duncan, I have used the set up exactly as you have described and it seems to work without coma e.g. http://www.astrobirdphoto.com/nebulae/M42.htm ...
Hi, Yesterday was a clear night with an almost full moon. Up to now I have never used all three narrow band filters (Ha, OIII, SII) during one session. So I...
That turned out pretty good Leonard. Narrowband imaging is great on bright moon nights. I have always liked the Horsehead Nebula. Your tricolor version is...
Thanks Chuck, Alan and Nick. I hadn't noticed the happy face until you mentioned it Chuck. I certainly see it now. I too am glad to see galaxy season coming...
Hi Buddy, Thanks. Its always nice to do some imaging on a clear night when even the moon is present. Previously I never bothered on moon lit nights. So narrow...
Hi Buddy, Very nice and interesting image. I love these images where one captures galaxy groups. I hope that when I have my new setup I will make a collection...
Hi Mark, Well, if you call shooting a nice crisp image of unforgiving star fields 'underwhelming', then ok! I'm mostly colorblind, and I can see the star...
Hi Leonard, Nice image! I haven't shot the full narrowband set recently. I was having trouble getting sufficient OIII signal sometimes. How wide (nm) is your...
Cool shot Buddy! Wow, 4 second guiding intervals at f/10! I would say that your mount is dialed in nicely. Do you set the guiding interval by using one long 4...

While waiting for the sky to clear and moon to wane I decided to reprocess some raw subs taken this summer. It was one of my first shots with my DSI Pro II and...
