I purchased an L-eXtreme filter about a week ago, and tonight was my first attempt in using it with imaging. Unfortunately, I didn't get very far. I use an ASIAir Pro with my rig, and I was unable to plate solve and polar align. While there was some very light low level clouds (rated a 2 on Clear Outside), I could clearly see Polaris with the naked eye. Once focused, I did notice that I did not see as many stars in the field of view.
When I went to do the plate solving for PA, it was only finding between 20-50 stars, and sometimes below. In the past, plate solving typically finds between 80-150 stars during the first step of PA. Once or twice it was able to plate solve, but when the ASIAir did it's 60 degree RA movement, it could never plate solve once moved.
I have a WO ZS 73II scope with a field flattener on it, and the WO recommendation is to screw the filter onto the back of the field flattener. If I cannot see enough stars to plate solve with this setup, I was wondering if I would need to get a filter drawer, and add the filter after plate solving...and if that would mess anything up since the WO recommendation is attaching it to the flattener.
Anyone else have a similar experience with an L-eXtreme and ASIAir Pro, where it cannot see enough stars to properly plate solve? If so, how did you resolve it?
