Not sure how this one came out. It was another test to see if I had the parracor spaced right yet. I think I might, but still have a bit of tilt acorss the sensor.

I got 19 x 300 sec on it before packing up, hadn't planned on imaging anything that night but these looked ok so I left things running for a little bit.

I also wanted to try out the new PixInsight features in this latest release so I used the new WBPP 2.1 preprocessing script, which is a very nice feature now if you use flats + flat darks instead of bias, made things much easier. Some gentle deconvolution, MMT noise reduction, then masked stretch, curves, etc.

I also got a copy of Affinity photo for the mac when they recently had it on sale for $38 - seems pretty nice and you can't really go wrong at that price. I may have gone overboard trying to adjust the color balance here, but its certainly a nice interface and fairly easy to use for a non-photographer. It also makes exporting a jpeg from higher res images that will be under 200kb much easier (although not sure I got that bit right either).
