Visibility II / V
In 2010, I practiced a little extreme astronomy and photographed Lyra’s ring fog on June 28th .
I decided to try the same or even better this year.
The first attempt was on Midsummer night, June 26, and yes, the ghost of the Lifting Weight Fog can also be seen there, even though there was a thin cloud gauze and I couldn't even take the flats.
I will also attach the image as proof of curiosity.
It has an exposure of 30x2s Ha.
Last night then a new company. This is not a beautiful picture, but it proves that it is possible to describe DS objects, at least within certain limits.
I applied 10-second exposures to the subject with a Ha filter that I stacked for about 10 minutes.
The boundary size class of the object is around mag 10.
With RGB images, the image began to burn through with 1-second exposures.
