Celestron, hot did you come up with the FOV size. I know you said approx, but an approximate idea is what I'd like to have for new targets. I can shoot through my scopes at 1000mm, 663mm 600mm and 500mm, 2 scopes and a focal reducer for each. Then I can mount my camera on my scope for wider FOV. When I'm trying a new target I'm never qhite sure where to start. Adding a focal reducer is no big deal. But changing out the scope requires a total reset for the mount setting, weights, realignment all that. And what is the star chart your using. I usually use Starry night, but it just has semi circles to show the approximate size of the object. Like on yours I can see the size of The N Am Nebula right there with the Viel. I usually choose a few targets, do some online research, look at Starry night, try a few sample shots and go from there. Sometimes I'll do sample shots for a whole night just to determine what I want to shoot later. And thanks again, you always have good information.
