About this image

Ooops. Sorry, I deleted my original post in error.

I think this is a difficult target being faint with a surface brightness around Mag 24, and with a very low elevation from the UK so it is visible only for a short time. I had tried it several times using my QSI 683 but could see little in the way of data on my subs. On this occasion, it was a case of checking that the scope was on target and then let the 294 camera capture what it could over a couple of hours when the target was just clear of the sill of the observatory. This is the result.
