Dumbbell in Ha

[rich_t]

This is the first image with my Edge HD scope for some time, mainly due to the slow F10 ratio (rumour has it the reducers might appear in the summer!). Looks like there's some collimation to be done as the stars on the left side are poor compared to those on the right. I also took some O3 but the seeing was bad and I'm struggling to produce the HaO3 image, think I might need to re-take these.

Exposure was 40*3min with an Atik383 camera at 2000mm, binned 2x due to the focal length/pixel size.

Thanks for looking,

Rich.

Nice bright and contrasty for just 3 min subs Rich, and a tantalizing glimpse of the very faint outer shell.

Thanks Tim, I think I need some kind of OAG setup before I can push the subs longer at F10 but I thought I should wait for the reducer for the scope to be released first so I can make sure the OAG will work with it.

Cheers,

Rich.

Wow - some great detail in there that you don't see that often!

Thanks, Rob- It's the 8" edge scope.

Cheers,
