This is another perfect target for the full frame sensor with SJH-75UH, taken at my backyard over the Bortle 8 sky.

SJH-75UF + Zeus-M, 10 x Ha/OIII each

Astro Pixel Processor’s star analysis was indicating each frame of FWHM values were overall lower 2 or less than 2. These result from my backyard in the city. So hopefully they will be further smaller if taken under the better sky. We will see.

This is 1st attempt by Sightron’s flagship model – SJH-75UF. I couldn’t complete the entire session because the marine layer came in. So this is 10 x Ha result.

The flat wasn’t applied in this image. It seems to be bright and sharp enough entire full frame sensor as designed. Furthermore, the image is free of star splitting, The bright star upper right corner is Deneb. No split! So quite clean star shape entire the field.

I got the feedback on AZ40 from one of our long-time loyal customers – Thomas Fischer. See his beautiful setup.

According to him, the mount is quite steady and still stable even during the focusing. Yes, I fully agree with him. I’m using EM31Pro in the top-mount mode. Quite stable. This top-mount setup is the biggest advantage for the serious visual observers, especially at high power.

Back in stock now.

By simply swapping the objective lens assembly, users can retain the existing mechanical design and accessories while upgrading to a different optical configuration.

I performed a star test last night at nearly 300× magnification, and it produced a textbook-perfect diffraction pattern. Very impressive!
