NGC6823 Reflection Nebula (John Kulin)

NGC6823 Reflection Nebula

I managed first light with my first observatory on the 27th July and didn't finish this until the 8th of October with the replacement dome.

I thought the original data might have been ruined because I stupidly hadn't isolated the pier from the concrete foundations and the old dome had so many faults that it resonated through to the guiding giving up to 2-10rms guide errors!

I didn't think I would be able to salvage any data.

Fortunately whilst the new Observatory was awaiting installation I asked my builder to come and grind a 2" gap all around the concrete pier and we managed to isolate it perfectly so when it came to collect the new data, it worked out nicely.

I had gathered the data over 6 different nights from the 27th July to the 8th October and it really wasn't too bad to process, I did lose 8 x 1200s (2hours) of data because at the end of each night the subject moved to just skirt above my willow trees (now pollarded) in my garden.

Taken with my GSO/Altair 10"RC/F7.9, iOptron 120EC, Moravian G2-8300 MkII and FW, 2" Chroma Filters, Pegasus UPB, Ultrastar Guide Camera, QHY OAG.

Here's the bumf: -

NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called Sh 2-86. The whole area of nebulosity is often referred to as NGC 6820.

M27, the Dumbbell Nebula, is found three degrees to the east, and α Vulpeculae three degrees to the west.

Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. It forms the core of the Vulpecula OB1 stellar association.

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.
