Ngc 5128. Image update.

[tilbrook@rbe.ne (Justin Tilbrook)]

Hi,

Finally had a break in the cloud early this morning.
Ngc 5128 was the target and hopefully part of a mosaic I'm planning.
Seeing was not the best but I'm happy with my result.

Image update.

Worked on this a little more and managed to squeeze out a little more.
New image on left

Equipment used.
8” F/4 astrograph , baader type coma corrector,. HEQ Pro 5 mount, orion mini guider.
Camera.
Unmodded Cannon 1100D. Cooler box.

11 x 8 minute subs ISO 800 , darks, flats and bias frames applied.
Stacked in Deep Sky Stacker .Processed in Photoshop 7 and Olympus background subtraction tool kit.

Cheers,

Justin.

Looks very nice with your setup. It's just a big dot with mine.

That's an amazing result for such a short integration time using an unmodded DSLR.
You must have very dark skies at Penwortham?

[Larryp (Laurie)]

Really nice result, Justin!

[RickS (Rick)]

Nice colour, Justin! I look forward to the mosaic.

Cheers,
Rick.

Thanks Kevin!

The 8" f/4 packs a punch!

Thanks Rick!

Probably take a couple of months before I have enough data for it.

Cheers,

Justin.

Nice work Justin, looks good. Any idea whats causing the slight movement in the stars at the top left?

Thanks Andrew!

Yes, still have a little field rotation going on. I need to refine my polar alignment some more.
There's also some slight coma, even using the Type 3 baader coma corrector.

Cheers,

Justin.

Smashing image. Can't believe how much you've captured in such a short time!

Alpal - why does it surprise you that it's a unmodified camera? NGC 5128 isn't known for its H-alpha and that all you gain from modifying a DSLR.

Because some of the red end of the spectrum would still be blocked
compared to a modified camera.

Looking good Justin.

Sharp with nice colours.

Good luck with the mosaic.

I agree with others' comments, very nice image for a short total exposure time.

Grouse results Justin definately found the outer reaches of the glow on this one, worth the extra time, yep. Dig the star colors to, see you have that worked out very well now as well ! Great stuff

Thanks Cam!

Good skies and a cooler box and you can get decent images out of a DSLR.

Thanks Bob!

I'm more confident in PS now, makes it easier to bring out the faint stuff.

Cheers,

Justin.
