Bubble nebula - first attempt at NB imaging

[Jannis]

Finally had a clear night so i could give my new filters a go.

This was very in a way fun, but in a way also so frustrating. First problem was focusing.. Even with the OIII it wasn't easy, but with the Ha and an unmodded 550D... >_<
After a few failed attempts at manually aligning the images i bought Registar.

I attempted bicolor following this guide: http://www.starrywonders.com/bicolortechniquenew.html
I don't think i got the colors very well, and the noise level is very high. I'm still happy with this as my first attempt as without filters i could only detect an extremly faint trace of the brightest part of the core!

12x 600s Ha @ ISO3200
11x 600s OIII @ ISO3200

Only managed to get 3 darks, and no flats. Bias added though.
Captured using Baader Ha 7nm and OIII 8.5nm with the Explorer 200 and my unmodded 550D.

What scope did you use for these pictures? This is truly amazing, great work!

Thanks!

I was using the SkyWatcher Explorer 200 PDS scope.
