Is there such a thing as photography Barlow?
Hi all.
I hVe a ts102 f7 scope.
Putting aside the obvious issues of imaging at f14 and the possibility of field curvature is there such a thing as a Barlow lens that is suited to astrophotography?
I have had a little look at the ts website and there are a couple of possible candidates. I would assume 2 or even 3 inches would be necessary.
I know it won't be cheap if it exists
Thanks
Scott
