Description

I received a replacement 135 mm from Samyang a week or so back and was immediately greeted to two clear nights in a row. I shot this with my ASI 2600 MC Pro and AM5 mount using LExt and LPro filters. I ended up with 5 hours of the narrow band data and an hour of the RGB data. I just used the latter for the star color.

Overall I was pleased with the lens good star shapes and the f2.8 certainly helps - I'll try f2 next time. Some quite challenging blue fringes on the stars which I don't get with the Askar 200 mm but nothing one couldn't handle in post processing.

I used Graxpert, GHS and Narrow Band normalization on this. I was really impressed with Graxpert!

Thanks for looking

John
