Re: March Full moon

I agree, I tried to push the color to the limits to see if I could get more information about the mineralogic composition of the lunar soil. It seems all young craters with fresh ejecta have a cyan tone, I thus tried to saturate this color more, to see if I could individuate young formations among ...

Nice image with good sharpness but for my taste a bit too much color, especially that Cyan on the top and bottom of the image, but OK I know, taste is subjective.

Re: Achieving Focus with a Zenithstar 61mm and Quark Chromosophere

Thanks for the advice. I'll get rid of the flattener. I had it in there for some night imaging and it may not have been necessary in any case with this particular camera. Its a ZWO tilter and I'll measure it to verify. The optical train would then be Scope-Quark-ExtensionTube(s) -Tilter-Camera, Aga...

Hi, Looking at your setup Setup: Baader 160mm D-ERF -> Bresser AR152L/1200 -> Lunt LS60 Etalon -> BF10 -> 2x barlow (for all images except the last one) -> ZWO ASI 462MM IMHO it is a vignetting problem, but I can be wrong here, caused by the BF 10 + 2X barlow and probably a non centered hotspot.

The global Truss runs at 12.5 kg
The plate and objective about 5.5 kg
The focuser assembly and about 4 kg

Total about 22kg

They have a digital zoom for the sun, moon and planets, but not for deep sky since the zoom only works on the jpg saved to the phone.
