The Session – 9th October

So, I did make a screen capture of the session on the 9th October, it is not particularly interesting as I was not really commentating throughout, had my webcam flap down for some reason, but you will see certain aspects – we are using the new SEP multi-star algorithm in Ekos, which is great for stability, it does show off the AS290MM mini, it shows how I have to manually focus every so often (APO and SestoSenso arriving soon will be greatly appreciated).

I would not expect anyone to watch this five hour marathon through from start to end, although if you happened to be watching it live it might be interesting if you were acquiring the same target, but certainly skipping through the footage, you might come across something I’m doing wrong, or right, and have some comments on my progress in this field.

Don’t expect so see the thumbnail in this video to appear in the video itself, this is the acquisition phase of individual sub-exposures, I will post a video on processing of the data, including this night’s, in a later video, when we’ve hopefully improve on the data substantially. The preview picture displayed is the accumulation of data so far, without any discarding of bad data so far.


I do have to wonder, how I will proceed when the APO arrives, it is a f/7 telescope, while these are taken on a f/5 telescope. Maybe I can proceed with a 3×3 mosaic, or something similar 3×2 or 2×3 and add to the data, or perhaps I need to choose to start all over again. APP will help when I start, as it will quantify the quality of the images I already have, and be able to merge frames from different optical equipment.

As always, if you are here as a genuine viewer with an interest in Astrophotography, then please leave a comment, I will moderate and reply if necessary.
