Description

After a couple of years of practice with my Samyang 135, I felt ready to purchase my first refractor . Quite slower, but four times the focal length!
I started experiments the day before, so strictly speaking this is the second light.
That's a pretty low target for my site that culminates only 19 degrees above the horizon, but it was the best time of year for it, so I decided to give it a try. It took me a year to find the time to process the stack, but here it is finally.

This was made before the second re-filtering of my EOS6D, so the raw stack still suffers from the elongated stars problem. A little RL deconvolution helped to fix them.

I don't have experience from other refractors but coming from the Samyang, I'm pretty pleased with the image quality . Except in the very corners, the stars are pretty tight. There is some chromatism, but that remains reasonable. Can't wait for the next opportunity to play with it!
