Messier 27 - HOO

Due to the light late nights, and my unwillingness to stay up very late and swap filters, I have simply let the scope image with one filter per night. Normally, I refuse to do this, because the lack of clear nights here would mean that it would take me weeks to take a single picture of one object - trying to image as much as I can in one night instead. However, because of the aforementioned position I am in, it has proven to me that taking one's time and imaging one filter per night actually pays off - unsurprisingly I guess, as this is the best M27 I have imaged yet. We also have fairly good weather here at the moment, which helps massively. It also represents the longest integration time yet for me, 3 hours and 12 minutes in Ha, and 4 hours in OIII - which equals an imaging time of 7 hours and 12 minutes, with each sub being 4 minutes long. I am pleased to have pulled out some of that fainter nebulosity too, even a tiny amount of Ha, I think, which is at the top of the faint OIII 'wing' on the right hand side, near to the orange star. I used my ZWO 294MM camera, with Askar 2" Ha and OIII filters, using the Altair Astro 130EDT triplet refractor. Thanks everyone and I really hope you are ok and 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.
