Messier 33 was always a challenge for me, I would either not get the entire galaxy in the frame or not take enough exposures (or take exposures long enough). In the past I would also have the challenge of not getting the HA regions to show up well (or at all really). This time I was careful to plan the session out thus selecting the right scope for the shot and I ventured into territory where I had never ventured before on this one, 10 minute subs! I now feel confident in my setup to go beyond 10 minutes even.

Man it was hot out during this capture but dithering is definitely all its cracked up to be. Manageable noise it gives to us poor folk without fancy schmancy DSLR coolers. Ok ok maybe I just have not gotten around to building one yet, lol! :-)
