Hi friends,
In a memory of the last solar maximum, from the abyss of my solar archive: a very imperssive bunch of sun spot groups - NOAA 12565/66/67 at a high resolution.
Equipment used: C14 + ARIES 385mm DERF + 0,25A etalon @ F/48 + 0,6x reducer + ZWO IMX174.
Thanks for looking.
Valery

Absolutely superb Valery however it lacks your usual smooth as silk touch, just a bit over sharpened to me (only going for perfection here )

This image was taken (and not FF calibrated) almost 2 years ago. Now my technique is abit better and the camera is better, as well as my latest etalon.

Valery, do tell, what is FF calibrated and what camera do you use now compared to the old?
