Hello,
I got some strange circled patterns on preprocessed pictures (with Siril 1.0.6).
When inspecting my flats I saw some vignetting and concentric circles and other strange things.
My setup is:
- Refractor APM LZOS 130 F6,
- APM Riccardi M82 Flattener (52 mm image circle) with M82 to M68 adaptor ring,
- M68 Zeiss rapid ring,
- M68 Baader tilt ring,
- QHY M OAG in M54,
- QHY CFW 3L 7 2'' filters with full set of Antlia Pro 2'' mounted with M48 threads LRGB + Ha OIII SII pro 3 nm
- QHY 600 M PH
- Home made flat box with ceiling light box with 224 led with white translucent polycarbonate + transluscent paper and white diffusing polycarbonate: much larger than the APM 130 aperture,
On luminance nothing appears and on others lots of things see attached pictures.
I compared with an Astronomik 2'' mounted filter in an Altair filetr box but with my previous camera a Canon EOS 6D MkII moded with astrodon filter and no rings on flats the sole vignetting is due to camera body.
Has anyone already got this with ANtlia filters ?
What are your thoughts about that ?
Thanks a lot for your replies.
Clear Skies !
