One of the highlights of the Southern Hemisphere sky, I was disappointed with my previous attempt at Sh2-311 with my RC8. A number of mistakes led to a very small field-of-view, so I decided to observe it at 555mm focal length with my Esprit 100.

It still didn't stop me making mistakes (I took half my frames at a gain of zero), but I am happier with the result.

Ha 24 x 300

[SII] 25 x 300

[OIII] 29 x 300

I still don't see the Skull and Crossbones (or the Ape or the Tropical Fish).

All I see is a Startled Donkey or a slightly Demented Lion.

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.
