Autumn evenings drawing in - it's dark by 8pm for some imaging now before bedtime 
Found asteroid Eros last night - my old software a little off but spacing frames an hour or so apart spotted its movement against star backround  Other targets for ETX-70 eg Jupiter, Moon, globulars M2 in Cap and M15 in Peg

M15 globular in Peg - one of my better DSOs shots - even 60s exp getting down to mag 15 stars - wonder how many of those you can see via the eyeball with BIG dobs

Thanks here's another 400s shot of the Splinter Galaxy in Draco that records two more exceptionally faint galaxies in the fov

Most impressive, Nytecam. I think you've proven serious astrophotography can be done with the ETX70.
I'd always wondered about that little scope... 70mm at F5. How much CA do you get on bright objects like Jupiter?
Do you use a wedge? It appears that most of your subframes are less than 30s. I wouldn't think field rotation would be a problem if you didn't?
I'd like to try it in color.

I do have a ETX-70 mounted polar on a tripod but I use my second ETX-70 OTA piggybacked on my polar mounted Meade LX200 with near pefect tracking
The ETX-70 objective is a simple 2-element achromat and reveals CA to my monochrome CCD camera - it's maybe x4 - x5 'faster' than a colour chip for much shorter exposures that go 'deep' for DSOs.
I'll leave colour for those with better skies than mine - I rarely get better skies than ~mag 3 to 4 and start imaging in late twilight as it doesn't really get any darker in the London suburbs
