Both cameras did well and they are close. However, I think the QHY-5L-II-M gave slightly better results especially with the closeup views. None of these images were cropped, only the brightness, contrast, exposure was adjusted in Photoshop. The QHY-5L-II-M Image 4 showing the crater Plato was rotated so it matched T3i Image 3.

Image 5 was taken on April 16, the night of the ISS Transit through the Orion 80 mm Short Tube refractor. I had this recording but it shut off right before the transit occurred. Fortunately I got with the Canon T3i mounted on the Orion ED80. For a comparison of ED80 vs. the ST80 look at Image 1.









Great comparison between the Canon T3i and QHY5L-II-M—the difference between DSLR imaging and dedicated planetary/guide cameras is really well demonstrated, especially in terms of detail and capture technique.
ReplyDeleteIt’s impressive how setups like this evolve, and pairing such workflows with modern ZWO gear shows just how far astrophotography technology has come for both beginners and advanced users!
