True corrector is not a kind of a cheep Barlow lens with a build in some negative (to SCT) spherical aberration - too many factors out of control. As soon as I will back home after Covid 19, I will post images in CaK with a true ccorrector. Rega...

Re: Sony IMX253 mono cameras

Hi Bob, Unfortunately, CMOS. Still far behind CCD. in terms of S/N. Since 2017 I was not able to find camera which was close to. PGR ICX445 mono CCD. 200 - 400 frames give much better S/N. Than 4000 frames Basler 1920-155. Use Basler. Due to high fps and more optimal sampling only. Look at Christian...

Hi Jozef,


Very nice H-a images.

But Mars is the most impressive. Can you clarify me - did you make this Mars with a 6" LZOS apochromat?
