NGC 6995 (rflinn68)

NGC 6995

This was the second of the two (7331) test images working with the spacing of the CCDT67. They are both heavily cropped, and the corners of this one still arent very good. I've since went to less spacing (and thus less compression) and it seems to be better, but still not perfect. Stars, even off-axis stars, look so good at f/8 using the TSFlat2, that I may never be happy with the Telecompressor. :/ I've ordered the Riccardi 0.75X reducer/flattener and will likely work with that some around full moon. Its always clear around full moon, right?!!

Anyway, with the processing of this image, I wanted to accentuate the OIII channel. The OIII always looks very nice on this target, and was much sharper than the Ha and SII. I ended up doing my standard hubble palette process with one version, then using pixel math, I put together a very OIII heavy version. It looked ok, but I wasnt quite happy with it, so ended up blending the two versions together to end up with this.

The custom palette version was this....

R: 0.6*SII + 0.4*OIII

G: 0.6*Ha + 0.4*OIII

B: OIII

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.
