IC 1311

As the nights get lighter and lighter, and I try to manage them, I obtained 100 Has, plus 86 RGBs, at 2 minutes and 30s respectively. I have fiddled around with this image no end, unsure of how red to make the Ha signal and so on and so forth, using various formulae and blends. Admittedly, I am not keen on my HaRGB images generally speaking, when there is a lot of hydrogen alpha across the field of view, because I am never sure that they look that natural to me. Maybe I am wrong, but I battle to get that natural sense with them, without overloading things. I think I prefer combining solely narrowband data together.

Anyway, here is IC 1311, which I have never taken before with an LBN and DWB objects in there, plus Patchick 6 (DSH J2009.6+4114), a probable planetary nebula, discovered by amateur astronomer Dana Patchick. You can just about see it, it is directly south of the main cluster and to the right, or northwest of the star HD 228037. Imaging time was 4 hours and 3 minutes. As I joked once before, I am sure the 3 minutes made all the difference - it looked like a Hubble image before I added them in! Take care. Simon

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.
