Rosette Nebula captured with William Optics GT71 and ZWO ASI533. The image has been cropped.
Roughly 4.5 hours integration with Optolong L-Enhance Dual Band Filter.
The image quality of the ASI533 is spectacular. No amp glow making image processing in Pixinsight a dream. Got down to -5 degrees very quickly. I like the square format of the sensor. I am using 1.25 inch filters in a manual ZWO filter wheel and experienced no vignetting.
Polar Alignment, Mount control and Image Focusing & Capture were all done using the ASI Air on my iPad. The whole set up is extremely efficient and works like clockwork.
