Good evening, everyone,
a more transparent sky than yesterday... but a breezy and colder air!
I always try to improve my flats at focus: transparent plastic bag in front of the sm40 for here. Works not too bad but not yet perfect...
always at fs60 + sm40 double stack + glasspath x1.25 + BF10 + zwo178mm towards 11h20 UT
regards,
stéphane - France

Re: sun halpha from february 25
thanks for the comments
Yes, with the small pixels of 178mm, the sun has a nice size!
some more problems with visible newton rings, next time I try without the glasspath (even if the sun will be smaller on the sensor )
cordially,
Stephane - France

Stephane:
When opened in another window, the FD´s are very good.
¿Have you tried to fine adjust your etalons, so to make the image more even in illumination?
Best wishes,
Eric.
