13/10/2021 Sun Protuberances Animation

Post by Arrakis97 »

Hi all :)
Attached animation of a pair of protuberances taken with 110 shots from 9 34 to 11 09 CET, 13/10/2021.

https://www.flickr.com/photos/carlocaso ... ed-public/

This is the configuration used:

Optics : Tecnosky 80/480 Apo + ZWO EAF + Televue Barlow 31,8 mm 2x
Mount : Ioptron CEM70G & Ioptron TriPier;
Filter : H alfa Daystar Quark Cromosphere;
Filter : IR CUT Baader Planetarium 2”;
Camera : ZWO ASI 174 MM;
Equivalent focal lenght : 4000 mm.
Software : FireCapture, AutoStakkert3, ImPPG, Adobe Photoshop, Adobe Premiere

Casalecchio di Reno - Italia
44° 29’ 29” N
11° 14’ 58” E

Visibility was not good; unfortunately I don't know how to measure it, and I don’t have a special instrument. Could you please suggest a solution to measure the state of the sky?.
Sorry for my bad Google transistor english

That's a stunning animation :movie :bow looks like a tug of war going on.

I'm not sure how you measure visibility but some people use an SSM to gauge the seeing conditions

An excellent animation Carlo.

As for seeing conditions without any electronic devices at the observers location, I simply would give marks out of 10.

10 = Perfectly clear-blue skies with no obvious air-movement/winds/contrails etc., at any altitude.

1 or 0 = Don't even bother to use any telescope or even the Mk-1 Eyeball, as usually total cloud-cover + plus heavy rain/wind/snow or even possibly the Sun (or any other heavenly-body) is being totally-obliterated by trees, buildings or some other structure and such as below the horizon too ???

Anything in between, really just needs a description of any "seeing" problem - experienced.

Besides electronic-devices can and do go wrong/give wrong readings for whatever reason...

Thanks Terry for describe this measure scale; on web i also found Antoniadi scale based on 1 to 5 level.
