NGC6823 Relection Nebula

[Jkulin]

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.

Lovely image John ? 

[Jkulin]

Thanks @gina

Thats a cracker John. I've seen that a few time in Stellarium when I've been roaming around looking for inspiration and have thought to try it with my 8" LX200 - but images I've seen of it have been less inspirational!! But your image is making me think it may be worth a try with the EOS700d and the L-eNhance.

Really nicely done.

Super image John, nice delicate colouring.

Cheers Lads, I thought it was going to be difficult with data spread over such a long time, so I manually processed it in PI and it only took me about 4-5 hours to get it right :-)

Wonderful image ? love the subtle tone of the the blue

[Carastro]

That's a really good result of a difficult target.  I found the Ha came out OK but trying to extract blue from the Oiii data was pretty impossible as it was swamped by the Ha.

Thanks Paul & Carole,

I thought it was going to be a mare, because of dragging over a number of months, but it was probably one of the easier objects that I have processed.

Unlike Sh2-185 that I have been working for two nights...grrr
