Pleiades, M45 (jewzaam)

Pleiades, M45

My actual first set of shots with the new EQ6-R and Z73. I didn't use dithering and wish I had given it worked quite well on the later M51 set. My subs were a bit long, getting some elongated stars. But it's good enough. I'll be back for more sometime! As for processing, I need to learn to "protect" stars when stretching to reduce bloat.

Description: Swapping over to PixInsight, touched up in AP to reduce a bit more background noise I didn't like. Maybe it should be there.. but I expect not given the DSLR noise madness. Also pulled blue up a bit for effect.

Description: Ever so slightly better processing. Removed one more sub, down to 21x120s. Combined with TGVDenoise and a "less is more" approach I'm happier with this. I moved to Affinity Photo for final small stretch and hue shift on the nebula. The Canon DSLR really shows with the noise I have to deal with but it's not as bad as on the barn door tracker!

Description: Many many changes to the processing workflow in PixInsight. Very happy with the final result though I need to work on protecting stars. Haven't bothered so far, but the stars in this version are just about the same as in the last version. The major difference is the background composition, sharpness, and color overall. I decided to keep all the subs except 2 that got some of a tree even though I notice inconsistencies in seeing. Maybe some faint clouds somewhere?

Description: Trying out a star reduction technique. I had to be pretty conservative and stick to smaller stars. Somehow all things got a bit brighter but I didn't pay too much attention to the processing after star reduction. I'll give it another go sometime I'm sure :)

Description: It's been a month and I've tweaked a lot of my process. Thought I'd come back to revisit this one. Using EZ Deconvolution and a better set of masks to process, I think the background is a little better and the nebula a wee bit sharper. I went a bit harder on S and c so it pops a little more. But still only 45 minutes, so going to have to wait something like 4+ months to be able to collect some more data. Well, start over given new camera!

H

Description: A month of processing learnings but I didn't spend a lot of effort on the background. Just wanted to see what I could get out of the nebula. Pushed harder on the contrast and color and if I were to spend more time on smoothing it might be better.

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.
