Deep Sky imaging on Ir & UV
For almost 5 years I am doing UV & Ir imaging in planets like Jupiter or Venus, and I have always wondered how it would be to use those filters on imaging the deep sky objects.
Recently I have finalised my system for observing and now I am ready to start experimenting on those new ways of imaging. First I have taken images of M42 because it is a bright and nice detailed target to see and I used the 8inch newtonian with a 801nm Ir-Pass filter and Atik IC on prime focus. The results were good but they became even better when I compared the image of this filter from the ED80mm telescope with the Ha line image from the same telescope.
Below is a comparison image of the Ha and Or807nm filters on M42 Nebula
