The Crab with an 85mm objective. Scopes of this size are not normally known to produce good images of M1, the Crab. But, I tried anyway since I am still learning the ropes with the IMX224.
Taken from the middle of a metro area in a Bortle Red zone. 8 sec seems to give good results with the LP levels at this location. More exposure just gets more LP and very little more, if any, faint target material.
Above is the gussied-up and gaudy version. Below is the not-so-gaudy version with less saturation and curves boost.
I also left more green behind, since the Crab has some green parts. It shows that better but also shows more of the LP that I had to cut through to get the shot.
Here is a roundup of objects I was able to see during my most recent Electronically Assisted Astronomy (EAA) observing session. These were taken in a Bortle Red zone and under a nearly full moon on Dec 1, 2017.
The moon still appears full and tonight (Sunday, Dec 3, 2017) is supposed to be the night when it is actually at its largest and closest to Earth at perigee.
It looked bigger to me the night before, but I guess that was because the weather was better. 🙂 To find out, I made an animated GIF that compares the 4 days worth of images:
It does look like the 4th moon is bigger than the others! So, it was worth it to re-setup the scope and get the shot. Lucky for me the sky cleared long enough to do it. Later that evening, the clouds arrived in force and it hasn’t been clear since.
Who knew just a few years ago that I would be shooting 8 second sub-images and building up images that rival my best efforts with a DSLR camera and 180 second sub-images. Now, all I have to do is save up for one of these new breed of Sony CMOS cameras with lots more mega-pixels that can match the resolutions I get with my Canon cameras. They are not too costly anymore and the results speak for themselves.
BTW, this was shot with the bright moon nearby. I got him, too, though! 🙂
