Leo Triplet III

My third attempt at the Leo Triplet, using just over 4hours of OSC data taken last night with my RC8 and 2.5hours of L-band data taken with Chilescope.

The L-band data helps to counteract the poor seeing at my site - exacerbated by the Leo triplet never getting about 30degrees from my shed. And the OSC data helps counteract my general incompetence at LRGB imaging. Add to this the avialability of the RC Astro tools, I though I might be able to do a bit better than my last two attempts.

Overall, I am pleased with the result. I picked up the tidal tail in the Hamburger galaxy, and BXT was able to pull out a lot of detail. This is my second L-OSC image (the first being the Angel nebula) and I must admit I am quite enjoying this way of doing things. Not sure whether or not it is the correct thing to do or not, but this is certainly the version of the Leo Triplet I am most happy with. Not least since it was imaged exclusively below an airmass of 2 for the colour data.

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.
