Re: Comparison between 8bit avi, 8bit ser, and 16bit ser when doing single capture of proms and disc

These types of comparisons can be tricky unless you run the tests in rigorous way as there are so many other factors at play. I always capture in 8 bit mode (SER) and can capture disk and proms at the same time and in quite some detail. It depends on the image capture settings (speed, gain, gamma) a...

Excellent images, Mark, as usual.
Enjoy your time on the canal. Hopefully the weather will hold both for imaging and relaxing outdoors with a few beers.

Monday Sun 12th April 2021

We're having quite a run of beautiful weather here, albeit a bit on the cold side with a covering of morning ground frost, so yet another opportunity for solar imaging this morning. FDs again in Ha and Ca II K. The region that hasn't quite developed into a sunspot (still a collection of pores) is lo...

Another beautiful day with an almost cloudless start, so another opportunity for solar imaging in Ha and Ca II K. With half decent seeing (for a nice change) I even tried a close up view of the bright plage area towards the east. Hydrogen Alpha FDs in Mono and Colour: Lunt 60 Basler acA2440-75 um 1....

Re: 30th March 2021 CaK C11

Hi Alexandra,

I guess the seeing conditions will have to be pretty near perfect on a C11 for calcium images. That’s probably the limiting factor at the moment, maybe?
