I thought I'd do some DSO
photography. I removed the focal reducer and set up with diagonal and Barlow
tube without the x2 lens. Instead I attached my Baader Moon/Skyglow filter at
the screw-threaded end of the Barlow tube. Attempted 10x30 second exposures of
M94, M51 and NGC7203 (the Iris Nebula).
Results once I got back inside were
awful, even when the exposures were stacked in Deep Sky Stacker. There simply
weren't many stars in the exposures. The filter was robbing me of stars. Don't
use this filter for stellar DSOs! Try it on nebulae?
Also, I realised my focussing left a lot to be desired.
P.S. I've just been reading a review of this filter on the Cloudy Nights website, and the reviewer suggests to just try holding the filter in front of the eyepiece (when observing visually), so that you can swap in-and-out and see the difference. Good idea, must try this.
