Leo Triplet

I don’t do galaxies, I have a new scope thanks to FLO, an ST102. A 102mm F5 achromat. I usually image in Narrow Band where the type of scope is not important.

Trouble is in spring there are pretty much no narrowband targets… so I went for the Leo triplet.

The transparency was really good when I set up, but quickly turned rather milky, which got worse as the moon rose. The wind also picked up quite a bit, but the ST102 is quite a small scope.

This image in 28 x 3 minutes, with Darks and Bias calibration frames used in processing. I will be going through the lights tomorrow as I’m sure that at least a couple need to be thrown out.
