Good evening

This video helps you set up your field of view indicator to enable you visualize what will be in your FOV when you point your scope around the sky. This is especially helpful for framing your targets.

Happy hunting :D

Hamza,
A couple of questions regarding FOV indicator setup - The camera I have is not listed in the CCD Camera list (at least not yet), and to setup a "User defined CCD" I need to know the Height and Width of the sensor, however my manufacturer only lists the diagonal size of the sensor. How do we get additional cameras listed in the CCD Camera list? My camera is a ZWO ASI071-MC Cool.

Thanks,
Dark Skies and Phenomenal Seeing!

I was looking at the spec's. for the Sony IMX-071. It only show's the diagonal dimensions. So I read up on APS-C. APS-C has a 3 to 2 ratio. So it appears that the IMX-071 may have a different diagonal dimension. The ZWO ASI071-MC Cool measure's out to 28.4mm. I came out with a 22mm by 17mm dimensions. Some other APS-C dimensions that I saw were 20.7mm by 13.8mm, 28.7 by 19.1, 22.5 by 15.

Hello Ed

I have found the sensor to measure 23.63mm in width and 15.70mm in height, this aligned with the diagonal measurement you found of 28.4mm. I will be updating the camera information list and push out in a future update.

Thanks for the find..

Hello Ken

This information was not readily available and required some digging around to find, i replied to Ed with the measurements I just found right above.

Thanks

Hamza - thanks for finding those dimensions out for my ASI071 - I went to the http://www.blackwaterskies.co.uk/imaging-toolbox/ link you gave me and got the details for all my gear... Now I have so much information, I'm dangerous!
