Catch up 17th April 2021

Post by Montana »

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

Immediately swapped to TEC140 stopped down to 100mm / 5x Powermate / Lunt CaK wedge / ASI174

Hi,

Very good. Interesting about stopping down. Is there really a difference between 140 mm and 100 mm ?

:shock:

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

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.
