NGC 6804 - Extreme Crop

I decided to see if my trusty EdgeHD 8 might be capable of imaging NGC 6804 after seeing Rick Veregin's recent image. This is a small planetary nebula in the constellation Aquila. The size of the nebula is about 1.1 x 0.8 arcminutes and the brightness of the central star is 14.4 mag.

I knew the small size of this target would push the capabilities of my scope so I imaged at f/10 and incorporated very aggressive dithering during acquisition. My view of this target is limited so the amount of time dedicated is shorter than I would have liked. I pushed the drizzle integration with APP to the max using a droplet size of 0.8 and a 3X upscale. Afterwards, I just used my normal HOO workflow within Pixinsight. Oh well, this one is done and I'm moving onto an even nuttier target of M 2-55.

Description: Playing around with more old data as I continue trying to master GHS. The revised processing did not improve detail a lot since the target is so small but it did allow a boost of the Oiii signal allowing more vibrance with the colors.

Description: Revisited processing with BXT AI4. The previous version went overboard with star reduction - even to the point of critical stars entirely missing. This version incorporates the full starfield.

Description: I thought I play around with some old data on this one and apply some of the new processes I learned from resolving the core of the Cat's Eye Nebula. I think this version benefitted from the new techniques but the small size of this target for my focal length still limited the end result. Still, the EdgeHD 8 does surprisingly well.

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.
