Thought I'd give the Viel Nebula a shot

Didn't have much luck with it last year, so I thought I'd try again while it was actually a clear night

Can I ask, how big a "rectangle" is this shot on the sky if you compare it e.g. to something that resembles to angle of view what a human can see at one glance (like 50mm on full frame)? In other words, if you take a FF 50mm shot to same direction, what is the crop you need to produce above image?

Well this is 650mm on a crop sensor. Maybe a little smaller than a sugar cube held out at arms length for perspective.

Very nice indeed, perhaps a little red. Its about a full moon sized if my interpretation of figures is correct but that is only a part of the veil complex overall.

Thank you. I guess that would make it the size of your thumbnail at arms length. Pekka you may try the North American Nebula it's pretty high now and it's very big and a little brighter than the Veil. I stuck the Moon in with the N Am Nebula below for size comparison. Both were shot with an 100mm lens. It's cool to see how many things up there that are actually too big to completely see with my telescope.

If you shoot with a FF 50mm you would need to have the camera mounted on some type of tracking mount . But with a FF 50mm the Summer Triangle should just about fill the FF 50mm lens . I've added a star chart with the Summer Triangle outlined in red with the 3 main stars that make up the triangle . It shows the Veil Nebulae with the appropriate size of what you can expect with a FF 50mm lens . Now this is approx. , it could be a little larger or smaller but this should give you an idea of the size to expect .

Your welcome but also remember that if you take a wide field shot like this above don't expect to be able to get the Veil Neb to come to size like the OP image . It would be so pixelated it would not look good . In order to get a image like the OP you would have to use equivelant lenses whether it be a scope or bigger lens .

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.

You can input sensor sizes and scope details into Starry Night and then get it to overlay the combinations of them onto the sky to see how the size works out. Really good as a planning tool.
