BORG 36ED is the shortest focal length as apochromatic telescope among BORG family.  I was curious how it fits the relatively small imaging sensor like 8300 chip in image scale.

Here is 1st attempt by our Jimmy. Well covers NA and Pelican.

NGC-7000-WebAnd I realize this 220mm focal length covers the whole parts of Veil in 8300 chip. So that should be next target.

  1. Hi Ted !
    How many images has he stacked to make this final image and what’s the each image of exposure time?

    I like to see what you did, too.
