Revision title: Re-Calibrated and Colour Tweaked

Clear skies have been scarce this winter, but I finally managed to get a clear night this week. NGC2237 in Hubble palette. I can't located my flat frames and need to re-calibrate but I'm happy with this one so far. Total of 2 hours and 45 minutes of integration time. (1 hour Ha, 1 hour Oiii, 45 minutes Sii) Hopefully the clouds will clear again some time and I can add some more data.

Histogram stretch applied separately to stars and starless image to preserve the white balance of the stars. The colour in the nebulosity around the stars is a bit off as a result and I'll play with it when I have some time.

Title: Re-Calibrated and Colour Tweaked

Description: Went back to reprocess this afternoon after adding some flat files to improve calibration. Also played with the colour balance to get a bit more of the reds.

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.
