Leo Triplet

My little astroimaging group went out to our favorite dark site last night. It got down to about 5 degrees F, but we had an ice fishing tent and a little propane heater. I can’t say that we were warm, but at least we could thaw out out fingers and toes now and then.

My goal was to image the Leo Triplet and was fairly successful. I didn’t get as many frames as I wanted because my laptop shut down a few times because of the cold and I had to restart everything a few times. I did get 16 frames to stack at 4 minutes each. I was using my Sony A7RIII camera, which is not controlled by my laptop so It kept taking photos even though my mount was drifting at times. I got some very interesting looking sub frames.

I haven’t been able to get out and do any deep space imaging for months because the clouds never go away, unless the moon it full.

I have been going back over a few of my older images and are tweaking them out of sheer boredom. Maybe I made this image better or not. At least I am getting some practice. We have been getting a lot of rain and snow in my part of the country for the last two years which is a good thing because of how dry it has been for the last decade or so. It would be nice to have a few nights with no moon and clear skies.

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.
