Havent had good weather for a while so deciced when I finally got a clear night with no work the next day to go for some small but fairly high surface brightness Planetaries

Here are full res. crops of the objects

First is M3-1 in Canis Major. 7x5 mins ISO200. Longer subs saturated the nebula. 2 faint "wings" just visible. Star Atlas Pro reports it as being mag 13.28 in H beta and 11.2 arc secs in size

2nd is M1-13. 4x10 mins ISO400. Both with uvir and uhc-s filters, modded 350D, 10 inch f5.6 newtonian. Mag 14.6 3 and 10 arc secs.
Warm night at 25 degrees, 80% humidity.

Nice shots, Scott :)

Those little fellas need focal length...grab a powermate or two and bump up the focal length on your next piccies. But you may need quite a bit better seeing than what you had, though. With that temp and humidity, it'd be like looking through an aquarium!!!! :)

Thanks
Yep its rare to get super steady seeing that allows the scope/camera to reach max. resolution in my location.

Another two interesting targets Scotty, nice work.

I can't remember, do you have digital setting circles..?

Thanks.
Yep I have an Argo navis, with encoders and gears adapted to the sampson mount. I bought it from Paul after he got his Losmandy mount.
