The Monkey Head Nebula (astropical)

The Monkey Head Nebula

This is so far my best nebula shot with the Uranus-C. I should concentrate on imaging easy fool-proof bright targets only. How I love bright nebulae. Even after merely 15 minutes the Monkey 🐵 showed it's fuzzy head. Actually, when you rotate my image 90 CCW (see annotated version) it looks more like a jet pilot with oxygen mask. Since imaging time windows are always narrow, a quad band filter performs at its best on bright objects which is no problem as there are quite a few in space. However, a LPF or IR-Cut passes notably more light. The "Balance of Terror".

BTW, after engaging power to the dew heater tape the FWHM value increased and dropped again after switching the tape off. Yet, a tape is preferred over a "Thunderstorm"-branded jet hair dryer.

Also worth mentioning is remote control which is of great help as long as nothing bothers the exposures. However if, then, you have to run to the gear on the devil. My current connection is implemented with an Android tablet and the scope controlling PC, both running TeamViewer highly appreciated by my dog 🐕, the only one missing me when I'm away.

My countryside internet is stone age, no, that would be unfair, bronze age, but fortunately the gear is orbiting at the edge of the habitable zone though quite eccentric, sometimes driving me close to the event horizon when the connection breaks. Also, I wished I'd never have found the tilt and aberration measurement tools in SIril.

The photographic "star chart" for the Monkey is a parallel capture on the same wind- and auto-guided mount.

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.
