sun halpha from february 25

Post by stef41 »

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

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.
