23.12.2021 Alway with my "home-made Lunt". testing for vignetting calibration

[Fedele]

I am working on additional extensions in search of the optimal setup, which vignettes as little as possible while guaranteeing adequate resolution and contrast in the full disk.

TecnoSky 60/360, Quark Cromosphere, ASI 178mm, ZWO tilt model II (i'm not able to use this well yet) TecnoSky 0,5x reducer, T2 5mm & 7 mm estentions in between camera and nose (i thin that an equivalent 31,8 mm estention between nose and 0,5x reducer will work better

removing all the estensions. just the 0,5 reducerì. camera resolution is alway at the maximum. telescope on full aperture

this is instead removing the 0,5x reducer
