halpha sun of January 4th

[stef41]

Good morning, everyone,

under a cirrusy sky (the clouds finally arrived last night:( ), a small sun of today with the fs60, sm40 double stack, glasspath x1.25, BF10 and zwo178mm around 12h10 UT still from the Sirene observatory on the Albion plateau (France)
I realized that I have a flat problem (like yesterday, by the way); I have to be more careful for the following times (if I see the sun tomorrow then )





cordially,
stephane

A bit smudgy but that doesn't notice when you view the Sun at original size glad you are having fun

precisely in the original size: there are many streaks near the active area.

Thank you for your appreciation anyway

cordially,

Very nice full disk ! Stephane

Hi Stephane...

A good set of images, and if you can clean them up in the future it will make good images great!

Fill disk flats are hard to do, good luck !!!

Another great full disk Stephane! Why are you running flats with a full disk? Are you getting newtons rings from the camera?

[stef41]

thanks for the comments:)

I no longer have a problem with newton rings because of the glasspath (I put a tilt ring) but I still have a problem with the 178mm halpha pattern! (this is a defect of this camera : viewtopic.php?f=4&t=20972 ). So I still need the flat.

cordially,
stephane
