Abell 61 in Cygnus with RGB stars (Pat Rodgers)

Abell 61 in Cygnus with RGB stars

Abell 61 looks like a planet to my eyes in Ha H+O (40-60%) OIII. With RGB enhanced stars. A lot of galactic dust in the image which due to the NB is showing blue. Hopefully the clouds will allow for more subs and the gathering of some Luminance.

Rev A: the RGB you can see the blue dwarf in the centre surrounded by a faint outline of Abell 61.

Rev B: The OIII

Rev C: The ha

Rev D: The NB image

Rev E: the combined colour images.

Rev F: Registered the Ha stack to the OIII this seemed to help with the star size. Re-did the blend for the green at 50/50 ha and OIII (previous version was 40/60) no discernible difference. Stretched this image this time using a masked stretch at 400 iterations with an aggregated background reference. Then finished the stretching in the HTF program. Added the RGB stars. A lot more subtle outcome.

A work in progress still.

Rev G: Tried to address the blue fringing on the whiter stars. Used the star mask and colour saturation programme, where I selected the blue tone and really de-saturated it down to -10 range. Stars are a tad better. Thanks for the pointer Dave.

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.
