Catch up 17th April 2021
Big catch up over the next few days. Let's start with the 17th April 2021. I can't really remember the seeing but I think it was very good.
Start off with C11 stopped to 10" / ARIES ERF / 2.5x Powermate / Lunt CaK wedge / ASI174
This was the only salvageable image

Re: Catch up 17th April 2021
Hi,
Very good. Interesting about stopping down. Is there really a difference between 140 mm and 100 mm ?

The Solarscope is doing very well, with top processing !
The TEC is definitely the winner when it comes to Ca K.

Re: Catch up 17th April 2021
Brilliant work, Alexandra.
Your Solarscope looks excellent, high resolution noise less detailed images, fantastic !
I have a lot of catching up to do as well on my solar work.

Lovely captures Alexandra, it takes time if you're busy to get through the backlog. I've a few days from April still to do and of course May. I need to get the April stuff done and sent off to the BAA. Thanks for sharing.
