Hi guys, in the past few months I have had various things on my plate. I got married in March and since then I have not done much in the way of imaging. In the meantime I wanted to sort out an off axis guider for my camera, and after being sent a broken one I am finally where I want to be with my guiding. I am now guiding through a TS 9mm OAG with my SSAG.
The reason I wanted to be using an OAG was because around a year ago I bought narrowband filters and posted an image here. Martin Pugh commented on the image and said that for narrowband imaging long subs were better. This made sense to me because then you can get long integration times without too much diminishing returns on stacking lots of frames.
This image is up too 11.5 hours of Hydrogen alpha in 30 minute subs. I plan to make a bi-colour image with some O3 data eventually but im not sure that I am done with the HA yet.
Critique is always welcome, my imaging has come a long way in the 2 years I have been doing this and its due to people telling me whats wrong with images.
