Cell phone manually held to telescope eyepiece last night. My telescope is a Cassegrain style, which displays images upright but mirrored or flipped horizontally. So I found a free app to flip it back to correct viewing. Next thing I need is a better app to post process on my phone or tablet. Photoshop is on my office Mac.

Meade 8" LX 200 telescope + Google Pixel 4XL cell phone

Color, contrast enhancement. Flipped from mirror image to correct view.
