November 29, 2020: Crescent and Crab

[michael.h.f.wilkinson]

Despite the moonlight, I decided to have a go at some DSO imaging, using narrow-band to battle the moonlight. I used my Meade SN6 6" F/5 Schmidt-Newton with ASI183MC camera and Optolong L-eNhance filter on my Great Polaris mount. I first grabbed about 1.5 hours on the Crescent Nebula, which I added to an earlier batch of data for a total of 5 h 18 min exposure.

Quite pleased how this came out.

As the Crescent moved towards the neighbours roof, I switched to the Crab Nebula, gathering just over two hours of data. By itself, I was quite impressed how much detail APP managed to get out of these data, as the moon was really rather too close for comfort.

I also combined it with earlier data, for a total of 3 h 17.5 min of exposure

Hopefully I can add more, and better data over the winter.

Looking good Michael.  M1 especially has some nice colour and detail coming through.

Incidentally, this was the first time i made my flats with the flat panel that arrived on Saturday. It reeally makes creating flats so terribly easy. Great tool

A lovely pair of images Michael.  Good to see a Great Polaris in action!
