NGC 4568 Siamese Twins Binning Experiment (Jerry Yesavage)

NGC 4568 Siamese Twins Binning Experiment

Still working on the optimal pixel scale for my C11 ASI 6200M combination. These data were collected at 1X binning and then binned in PixInsight. Here is the basic ZWO page on increasing SNR via binning.

The image from PixInsight shows how much brighter that 4X binning is compared to the 1X. The star count is also much higher 212 versus 149 in the typical monochrome image (Red in the example).

You can also do this in the ASI ZWO software:

In any case, for me the binning seems to give me added SNR and I can live with a 4X binned pixel scale of 1.1 Arc"/pixel. This is very good for my sky.

I think I will go back to collecting all 1 binned images and keep experimenting. Maybe there is a happy medium at 3X that gets me more detail.

This gives a range of star number readings for 1x 2x 3x 4x. 3x might be better in some situations... image scale would be 0.84... maybe I can get better resolution in narrowband.

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.
