Finally, today I had a short moment of clear sky and a chance for First Light!
After disassembling and cleaning the lens, I've installed them back not even trying to play with collimation. I tightened the screws just to stabilize the lens - that's all.
Well... I must say that I did not expect what I saw today...
I had a look at Mars and the Pleiades. 120x magnification with the ortho Zeiss O-10 eyepiece. The planet disc is drawn like a razor blade. Beautiful, juicy colour "ball". The slight phase is visible. At this magnification and the current planet size, it is difficult to say that you can clearly see details on the surface, but I could clearly see there are darker patches on the surface. Aberration at a level that is difficult to distinguished from slight eyepiece aberration and the blurring caused by air movement.
Unfortunately, before I managed to setup my SW 120ED to compare the picture, the sky was overcast again. But I had the impression that the aberration was not clearly much worse than on ED. Even with the ordinary H-6mm eyepiece, the image has not suffered much from aberration while maintaining precision and contrast.
Then I managed to get a look at the Pleiades using the wide-angle Polarex MONOCHRO 40mm eyepiece. What a Beauty! Perfect stars, blueish sharp points...
My shortest summary of the first impression: YOU DO NOT FEEL THIS INSTRUMENT! You don't feel the optics, the glass, lenses that are between you and the stars - you are just THERE! :-) Honestly, I haven't felt it for years. And now, unexpectedly I've found it again! Maybe just for a moment, until I get used to this incredible instrument?
I hope not :-)
