It was finally a clear night last night, so I got to use my new RASA 11 again! This time I shot M81 and M82.

 

I decided to see how my mono camera with filter wheel works with the RASA 11. I was wondering if the large filter wheel would affect the image too much or not.

 

It looks like it will work fine with the filter wheel and also with my normal filters. So I won't have to buy the expensive 2" "fast" filters for this scope. Some of the stars are very slightly out of round, but I think I can fix that with making a mask to sit in front of the filter wheel.

 

Anyway, here is the photo. This is an integration of:

 

Lum: 200, 20 second images

Red: 48, 45 second images

Green: 48, 45 second images

Blue: 48, 45 second images

H-Alpha: 40, 90 second images

 

Celestron RASA 11

ZWO ASI183MM Pro

EQ6-R Pro

ZWO ASI290MM MIni Guide Camera

That's a great image. Well done.

 

What size filters are you using out of curiosity?
