SH2-296

I took three images of SH2-296 the last 5 weeks:

1. with a Canon EOS R and the Astronomik UHC filter on Feb 24th
2. with a Canon EOS R and the Optolong L-eXtreme dual narrowband filter on Mar 12
3. with my ASI 6200MM with Ha, SII and OIII narrowband filters on Mar 26-28

This is the last one of the set and its interesting to compare the three images.

I find that the colors of the two images with the Optolong and the Ha, SII, OIII filters are very similar. With the Optolong filter and the color camera the exposure time was 3h10' whereas with the three narrowband filters and the mono camera the total exposure time was 7h30'.

However, angular resolution and sharpness of the image is much better with the mono camera.

The latter is of course to be expected, but the good color and noise of the second image shows nicely that color cameras with a dual narrowband filter are also a good choice for astrophotography

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.
