M27 LRGB , LRGB-HSO, and SHO with RGB stars (Pam Whitfield)

M27 LRGB , LRGB-HSO, and SHO with RGB stars

Still managing to get some imaging done :-)
Difficult to believe I haven't done the Dumb-bell since 2015 when I used a 80mm scope and DSLR!

Longer evenings make accumulating a decent amount of time on a target less of a pain so there is about 4hrs on this from 2 nights. I decided to stick with LRGB for the time being as it's easier to get a decent number full subs when partly cloudy.

I should have a play to get the star sizes to match properly on each channel - however the image does pick out the colour constrast in different shells of gas quite nicely.
The image is cropped in quite a bit so is x2 drizzled.

If I'm lucky I can add a bit more time on it as well as the other target I'm working on.....

Description: I collected some narrowband data over a couple of nights and tried a combination with LRGB-HSO in APP. There's about 2hrs of Ha and 1.5hrs each of Oiii and Sii.
Some of the fainter surrounding nebulosity is starting to appear so it's definitely getting there....
I think I'm going to keep playing and try processing the nebula and stars separately and recombining.

Description: Dipping my toes into Pixinsight so it seemed like the time for a bit of an experiment!
This image used Starnet++ on the APP stacks to separate the nebula from the stars and then recombined the SHO nebula with the RGB stars. It's a very different look from what I normally do but it really emphasizes the nebula over the multitude of stars.

Description: That's better figured out some of the pixelmath syntax :-)

Description: Background not so clipped on this one and a better balance between the stars and nebula

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.
