Hello
Here 's my first attempt at the Saturn Nebula.
Tiny little target.
My C14 needs some collimation I think.
Still I'm pleased I managed to get something out of it.
full frame (minor cosmetic cropping) and cropped version.
C14 at F/11 on G11 LRGB 90-30-30-30
thanks for looking
frank
EDIT added a few frames from near full Moon but only exposed 2 and 3 minutes as test shots and sure enough I'd burned the core before so i add a more detailled quick repro. I will reimage properly shortly under new Moon skies.
cheers frank
I tried to have a go at it again but there is no helping the fact that the core is burned out
What I need is to re-shoot with shorter exposure and layer in the better core etc.
Maybe next week?
will see
Thanks for the feedback
much appreciated
frank
Hi Frank, I just had a look at NGC7009 on The Sky 6 and saw that there is another planetary PLN 37-34.1 only 38" from it, magnitude 8.3 and 0.4'x0.4' . So should be within the FOV on the cropped image. Strange that there is no sign of it.
Just did a google search and states that NGC 7009 and PLN 37-34.1 are the same object. Just goes to show some planetarium programs have a few mistakes within.
Miscollimation aside, that is probably the brightest image of that PN I've seen. Very nice. Good luck with the shorter exposers in the coming week, look forward to seeing the results.
Top effort, long FL imaging is a challenge, once you are over 1500 mm seeing kicks in noticeably, at 3911 mm that's way over that and seeing will play a big part. Well done I say.
Maybee you will get more next time, look forward to the results
Frank I like this image. If you collimation is out it is not noticable in this image. The stars a eveer so slightly misshapen and this could have occured for other reasons than collimation.
