NGC 2017 - Reflection Nebula

This is a very dim area of the sky, so I will need to add a few more hours of exposure.

This nebula has pushed me way past my comfort zone, I realize that I have a lot to learn about PixInsight. Even after 11 hours of imaging I have way too much noise and the colors just don't look right. I think the best way to image Casper is from a very dark site and take a lot of longer exposures

I took 3 minute subs, next imaging session I took 5 minute subs. Still too much noise.

Square Root Rule - as the signal is increased with longer exposure times, the noise will increase to the value of the square root of the signal. So longer exposures will have a high SNR, just don't take exposures that will blow out the light areas.

If you look carefully you can see three different faces inside the Casper Nebula. In my image two of the the faces are looking to the right and the third is behind the other two in the blue region.

To me, NGC 2071 is a very interesting part of this photo. It looks like the face of an animal. I think it looks like the cat from 'The Cat in the Hat'.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
