Ngc6746 & ngc5740

The near and the far. The bright blue foreground star is magnitude 3.7, 109 Virgo at 134 light years and the edge on galaxy on top is NGC5746 at around 90 million light years. NGC5740 is at the top right.

GSO 10" F4 Newtonian, full spectrum Canon 1100D, 1128 x 30 seconds unguided on a HEQ5 Pro. About 9.4 hours over 3 nights. Yes that is 1128 frames. Poor camera lol.

Love it! Nice details in the two galaxies too, but that star and framing makes the shot.

Nice 3D effect there, and well framed Kevin!
Gee, 1128 subs?
You must have a supercomputer to crunch all that data!

Thanks Marc. Yes, the bright star helps frame them. I like bright stars in a galaxy field.

Thanks Andy! The PC is just an old i5 laptop. I let it stack in DSS while I sleep. Takes a few hours.

Very nice result Kevin. 1128 unguided subs on with a 10" on HEQ5 - this must be a record for sure!

Great pic Kevin. Brilliant perspective with that bright star in the foreground.

Thanks Suavi! For lucky imaging, the more subs the merrier!

Thanks Pete! Yes I think the bright star adds a bit of interest.

Kevin, the shots you post are truly inspirational. The effort you use to produce quality like this with a DSLR gives those on a budget hope that all is not lost if you can't afford a dedicated CCD camera and the technology that goes with it. Thanks for showing us what can be done. By the way, that's a great shot and lovely composition.

I'll add my compliments to the others. I've always known that with enough
effort, and some talent, great results can be obtained with a DSLR, although
I've had a lot of trouble persuading others.

Impressive Kevin. Getting a 3.7 mag star in the same field as a faint galaxy without the star blowing out is pretty skilful

Thanks Michael and Ray. Total time matters more than anything and I think most people don't put in enough time from their DSLR shots. DSLR's also like low F ratios. It's by no accident that I chose a fast scope. Fast F ratio + time + DSLR will usually get a good image.

Thanks Rick. I like most bright stars but must admit that Alnitak is a pain in the rear end.

Expensive imaging, You'll probably only get about 60 or 70 images out
of your 1100D using that many subs.As it is a budget level DSLR it
probably wouldn't be worth replacing the shutter unless you did it yourself.

Nice edge on and almost face on galaxies. I like the colour and the bright central star with diffraction rings is an interesting touch.

Yes I'm aware of that particular fateful end. I'm working toward an astro cam. Hoping the camera survives until then.
