M-83

[FOOTPRINT]

Hi All,
Had another go at M-83, results herewith, this is 4 x 10 Min. Exp. at ISO-800 with DF removed, using the LX200-10" at F-10, guided, there is a bit of error in the guiding due wind, The colour is untouched, looking at AAO and other Pix. on the Web I note that most Pix. show this object as a Blue Hue, with some red stars (these are BIG scopes) not what I get, but maybe due to not enough light getting to the Camera with this high F-ratio.


cheers........Jim

Hi Jim

Nice Pic, I tweaked the stars a bit:thumbsup:

Cheers

Jim, how are you focusing ?.
As it still is a little out of focus.

You have all that detail and its being hindered by focusing. Great exposure, with what seems to be good detail that is washed out a little.

Possible switch over you imaging times, and do 10 x 4 minutes next time to remove the guide errors.
Your S/N ratio will be as good too with multiple images.

Very nice.
Did you use Neatimage or any other image smoothing software?

Hi All,
Many thanks for all the comments, and Fred that sharpened things up a bit, yes the Focus is a bit of a problem at F-10, but looked good, I feel that guiding is the problem, im using an ED80 + MX7C, a bigger guidescope would help, I did better on NGC-5128 (Pix. attd.) for some reason even though its about the same RA/Dec (approx.), trying.

cheers....Jim

I take my hat off to you Jim, despite the small glitches you've done extremely well on these.

Keep them coming mate.

[Garyh]

you have done a great job there Jim...It would be hard to get guiding spot on at that focal length!

[Ric]

Great images Jim, f/10 can be tricky but you are doing some nice work.

Cheers

Nice, just a few tracking problems though. ;)

Jim, regardless of the few errors you mentioned, i reckon it is a top shot, i like it,

Jim, judging from the strength of signal in your pic I think your next image of this will be top notch if you can nail the focus.

Hi All,
Many thanks for all your comments, and yes, guiding/alignment was the problem, I sat at the scope/mount for a couple of hours last night and found that the drift (N-S) was a bit out of limits, so adjusted the mount to compensate, if its not spot on the guiding does a bit more work and shows up in F-10 Pix., also long exposures overhead show up the misalignment even though short ones (10 Min.) dont, a series of Pix. taken cannot be combined (aligned) as the stars in each successive pix. will be displaced by the drift, always something.

cheers.......Jim
