IC 1805 experiment

[KyleStoke]

This was an experiment to see if i could automate an imaging session with a camera lens.

So this is a Canon FD 200mm lens with Atik 428ex.

The rig

And this is the result 9 x 600 Ha, 10 x 300 R & B green failed so synthesized, they are a bit blurry either the focus was off or the spacing wrong.

The ha looks great and the lens has done a great job but the colour hasn't quite come off.  Stars will be much more attenuated through a narrowband than a broad band filter.  The colour might be ok for the nebulosity but you are always going to struggle with the star colour and the stars will appear bloated in B+G compared with Ha

Hi Martin, yeah red and ha were a lot better I'm sure that the spacing wasn't quite right and left a lot of subs with a kind of hula hoop stars
