M35 and NGC 2158

Two "open" clusters. NGC 2158, 5X further away, actually looks a bit globular. M35 is quite irregular, members occupy most all of the frame. This target looks different at different FOVs, this is about as small as I'd want to go.

Normally I use MorphologicalTransformation to reduce star size, and tone down "too many" background stars. In this case I just didn't stretch it hard. That, and using the arcsinh stretch got me good star color, you can see some variations in the usual blue and orange. the price one pays is a less vibrant image.

RGB were 14,18,18X60, flats were 20X3.

Description: Decided the first was just too saturated, too lacking in background stars (which also cut out some of NGC 2158). Replaced the arcsinh stretch with manual histogram stretch. A bit of sharpening.

As always, a lot of fairly subjective decisions.

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.
