Trying out image scale with my telescopes used my 80mm refractor with this one. I did re-sample it by 2x, giving the impression of using a 2x Barlow lens, which I am yet to purchase.

The image scale tests are being done for the up coming Solar Transit of Venus on the 6th of June and also the November 14, Solar Eclipse. Using the moon it gives a good idea on size of the suns disk without having to put the solar filter on all the time.

This is a stack of 6 images 1/125sec each. Slightly under exposed.
