Large prom NE limb 04/08/22 90mm refractor!

Post by Radon86 »

Hi all,

On a day with quite good seeing, I managed to get my 90mm F10 refractor working on my Quark +ASI174mm camera on a EQ3-2 Pro mount.

Quick processing in AS!3 and Imppg only. Here is the prom and another one with some disc detail and active region, in the North East limb.

A single video file taken, not separate disc and prom videos in Firecapture. Approx 11.30 to 11.30am BST on 4th August 2022
10% of 1000 frames: 16 bit SER format

Focus obtained at : Diagonal +43mm on focus tube for visual
Focus obtained at: Diagonal +38mm for imaging (ASI174mm) : no newton rings seen, no tilt adaptor or flats needed for calibration!

I only had a few minutes before the cloud came back so it was nice to get some quite good captures !

Thanks Alexandra !

I think I was extremely lucky. It was cloudy and I only had a few minutes to get it. I may not get a better image for the next 10-15 years !
