Well guys,

I really thank you all for the feedback and the nice comments. I'll try to complete this project as soon as weather clears here :C

M3

Posted By Gianluca Valentini
Well Jason, I like it a lot! I can tell that you had a fierce battle with a noisy chrominance, but you came out winner since the image is very pleasant overall.

Congrats grin

M3 & M35 using Canon Powershot A350 Afocal

Hello Jason,

considering what you used to do it, you couldn't ask for much more.
Globulars are not an easy target, I believe, but at least don't need much exposure to appear on your images.
Now you can only multiply the number of shots and then stack them to see what happens wink

Ciao

Saturn 12th Feb from murrumbateman

Absolutely STUNNING 8O

I think that not only the Cassini division is very well defined, but I can see a hint of what seems the be the Encke division.
Congratulation on one of the best Saturn images I've seen in a while!

Stunning image Dietmar! Fascinating object too.

Thanks for bringing to my attention: I may try my luck at it in the next few nights if the seeing and the weather assist me!

RGB combine question

Posted By Gianluca Valentini
Hello again guys!

Unfortunately I don't seem to have much luck with RGB: I've never been able to put together a decent one so far unless I used my OSC camera :C
Now I have 14 10min subs af all 3 channels (the seeing wasn't that good, so I opted for unbinned colors), but my B and G averages are really weak and the final image is truly awful!! I sure need to apply some flats, but I thought that the combined image without flat fields applied would have been full of defects, but not that it would have very weak color. What could I be doing wrong?
What happens is attached here :C :C :C :C

Synthesized color from Luminance

Posted By Gianluca Valentini
Hello Floyd,

it sure would be nice to know how you did it! It may be the only way I will ever get a color image without using my trusted OSC ST-2000 sad

Ciao Floyd

Mars from WSP2008

Posted By Gianluca Valentini
Beautiful image John!

Everytime you come back from the WSP you bring nice presents: I still remember a Saturn you posted sometime ago that was probably the best I've seen so far!

Thanks for sharing John.

Very nice Jim. I had never heard of the King Cobra cluster before: I like the name and I can see the cobra shape!

A Late Holmes

Posted By Gianluca Valentini
Hello Dan,

well this is a very nice image of Holmes: better late than never wink

I just got back from a week on vacations and the weather is not good here, so no imaging sad

In the meanwhile, Tyler was able to get my files of the Rosette and is trying to work with my RGB data. I can't wait to see what will come out of it, but I'm sure that with his expertise he'll do a great job with my data!

Ciao Dan
