Ability to carry out PA with FoV very large

[ashirwad]

Greetings. I have been using Sharpcap Pro with specifically polar alignment feature for following configuration-- Fornax LighTrack II mount, Manfrotto Tripod and refractor 115mm Primary with F7 ( 800mm focal length) and QHY CCD 268C camera. For a specific outstation trip, I wish to replace 115mm refractor with Canon EF lens with specifications approx 115mm focal length, F2.8 . With my 268C, I calculated the FoV to be approx 12 deg. Will Sharpcap polar alignment plate solver work with such a wide field? If yes, any tips, dos/donts, limitations?
Thanks and warm regards...Ashirwad

Hi,

I think it is probably unlikely to work with a 12 degree FOV, but of course the solution in this case is luckily simple... Just use the ROI feature of the camera to reduce the area of the sensor that is being captured and therefore reduce the ROI. Something like 1/4 to 1/3 of full resolution in each direction should work fine.

cheers,

Robin

Robin...Oh, thanks so much. I got your point. Warm regards...Ashirwad

Of course, getting a *wider* field of view is a much tougher problem (or at least, often a much more expensive one to solve...)
