Crab Nebula (M1) 2021-03-07
This image represents a good start in imaging M1, and a good start on learning PixInsight. I have much more to do on both counts.
From an image capture perspective, this is an LRGB image comprised of 25 x 360s luminance subs, 3 x 500s red subs, 3 x 600s green subs, and 3 x 500s blue subs. I seem to have most of the nebulosity captured in the luminance channel, but more data would help. I definitely need more data in the RGB channels. I had to push the saturation too far to get the reds and pinks to show up.. There are no dark, bias or flat frames used to compile this image.
From a processing perspective, this is the first time that I have used PixInsight for LRGB processing since early December, and my first time using it for a nebulous target ever. I think that I have most of the linear processing down fairly well leveraging what I learned with my Orion Constellation OSC images from late January through early March. Most of what I have yet to learn is in the realm non-linear processing.
Where to go next? I used the TeleVue NP101 to shoot this. I could collect more data with this scope, because I think that it looks pretty good for an image scale of 1.39 arcseconds per pixel. Alternatively, I might want to go after it with the 12" f/8 Meade instead of collecting more data with the NP101. I believe that I would need to use 3 x 3 binning of the sensor's 3.76 micron sensors with the Meade, which would result in an image of just less than one arcsecond per pixel. That's a slight improvement, but perhaps the NP101 will win on optics performance? More to learn in this space (sic) as well.
