Acquisition type: Lucky imaging

I actually see two Dervishes. The centrally placed smaller one of IC 1871, and the larger one of SFO 12 in the top right which looks like a Dervish with his arms raised, above a large black funnel shaped skirt.

Not to be confused with the nebula of the same 'common' name in Carina (NGC 3247) - visible only from the Southern Hemisphere, IC1871 occupies a gas filled FOV that is just a very small section of the much larger Heart Nebula. This image took up my entire field of view on my 14¨Dobson. Captured using a dual band filter, in only 20 minutes, using just 300 4 second subs. Transparency was good, and seeing was average to good. With very little cropping and some playing around in Startools, I was able to come up with this image. After the Wipe module, mainly Filter to increase H-alpha and Superstructure, some noise reduction and further enhancement of blacks and noise reduction in LRC.

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.
