Hi,

Having fun imaging with my new setup.
Decided to stay up late and image M83, a good starter galaxy.
I didn't use my coma corrector, having issues with this, don't think it's matched to the scope. Iv'e almost solved collimation problems, what a bugger of thing to collimate an 8" f/4.
Still I'm happy with the results, considering the problems and hot night.

Telescope, BINTEL skywatcher 8" f/4 astrograph.
HEQ pro 5 mount, impressed with this!
Canon 1100D, prime focus.

8 x 180 sec exp, ISO 800, 3 dark frames and 1 flat.
Stacked in DSS, processed in Photo Shop.

Three images, original stack and two cropped.

Cheers,

Justin.

A couple of things to think about

1. more data
2. tracking or flex issues some elongated stars although not bad for unguided
3, Get rid of the green tinge
4. check each frame before stacking to make sure all ok and no tracking hiccups
5. More darks and flats may help with the noise DSLR's are not the best on warm nights

Cheers

Keep it up Justin, it gets more addictive the deeper you go.
A great start and don't forget to enjoy each moment as it happens.

Hi,

Thanks for the tips and encouragement.
Trevor has raised a question, what is a suiatable amount of darks versus subs, for a uncooled DSLR?


Thanks,

Justin.

Check out "Jim Solomons Cookbook"

he's done a lot of work with a modified Canon 350d so may give you some help
