opa, your digital camera shots were much better than your 120 images. This 20Da shot was nice.

Nice job! It is better to make fewer images but good ones.

Kingarthur, you enjoyed your trip?

My telecope looks a bit foggy when I look through it. I took an image through my telescope using my phone camera last night. The Ronchi Test Images are attached here. My telescope is at f/5.77 with D = 120 mm and FL = 692.5 mm.
