M27 with Faulkes Telescope

Another image from the distant past....
I used the 2-metre Faulkes Telescope North on Maui, Hawaii, to create this four-pane mosaic of M27, the Dumbbell Nebula. The original observing run was on 11-06-2008 and consisted of three 75-second Ha and three 90-second OIII and H-beta exposures per pane. If I've worked out out properly this equates to about 51 minutes total exposure time.
As mentioned in an earlier post, the FTs didn't have autoguiders back then so exposure times had to be kept very short. Some trailing is evident in parts of the image. The native field of view of this telescope was a mere 5-arcminutes, hence the need for a mosaic. I used an early version of The Sky planetarium software to work out the RA and DEC coordinates for each of the panes and the telescope pointed quite well.
I've reprocessed the original data for this version. The original image was used as a NASA APOD on 26-06-2008.

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.
