NGC2035 / N59A in Narrowband

[Bassnut]

After much confusion, it turns out this is incorrectly labelled as the Seagull Nebula in Sky 6 and again in Sky X (sheesh, youd think they would fix that :P).

This is by far the dimmest object I have imaged. I cant find the mag anywhere, but Ha on my 10" (f8) was so buried in noise, even with 20min bin2 exposures, I gave up and used earlier Ha data from my LX200R 12" at f6.7.
The max ADUs on the 12" were some 350, out of 65000 :eyepop:, and for the 10" even less at bin2.

I like the look of this Neb, so I collected some 6nm SII and OIII bin2 data on the 10" to make a starless Ha:SII:Ha:OIII here (http://4256458530705943474-a-1802744773732722657-s-sites.googlegroups.com/site/fredsastro/home/NGC2035%20NB%20starless%20final.jpg ?attachauth=ANoY7crfKTlIniLPrAnbjgK bEeTF5qN0DJ-uAwDo9I-SffRvYBLn9Zb-zLJQbXo8hNzf55HRhCAqFZArMlNcGMhYyi-k6FdHnb7kFdQP1fSWkEQqEoQoqfoSfAzpGL 96R4fSRaauLm934B0pWHhBH7PnOmJ5GCHyJ LN2MLsAqFQL2cJC5BjrPDNwATtZJa1zLiip Jq3J5ryn3-pf_Jxm4zQWBrTfH5X_2UGG1BlWKW5530f9n HIUPZs%3D&attredirects=0). The N59A neb is particularly interesting.

The earlier LX200R 12" HaRGB is here (http://4256458530705943474-a-1802744773732722657-s-sites.googlegroups.com/site/fredsastro/home/NGC2035HaRGBfinalsite.jpg?attachaut h=ANoY7cqM5VH2Tgj6YkMYrc52WWo3DDqBJ Y9P35bucwrOhdwssKZdOVsJa4ybSUsjY7I2 bBAzxGeYnifpwWl7ChQp57Y-G9YHrE4uzweB3laElgqa_Chvj8YU5gNSHOT W5uBxFPyXP8Me5O_jNDVRSJQKgHrdh0Gy58 sL2gnsmZSQF--d3eUyaqSILxgHedDkgMUoDkEvK55_UNpWvv Uz6D1Mn0g1KVIZ-g%3D%3D&attredirects=0).

Its artifact/noise city unforch. Other (few) examples on the net are taken with bigger flash gear, Don Goldmans (http://old.astrodon.com/_img/image/gallery/2/NGC2035Web2.jpg) is a stand out, 16" and dark skies sure makes a diff :P, I cant get close to that. The SII and OII were taken with the full moon up.

Amazing aesthetic to that object Fred. Reminds me of a Gleeson or Ernst oil painting. With the time taken to get it, it might as well be in uil as well.

guy

[Bassnut]

Thnks Guy, yes, I thought id go with asthetics, given there wasnt much of anything else. Art works, ill go with that :thumbsup:

[Paul Haese]

Love the HaRGB version Fred. An object I have not seen before. One to look at some time.

[Alchemy]

Certainly not a regular target, dons image is a standout for sure, I have a preference for the haRGB version..... Of interest, down at 6.30 or so on the ha version the stars are different to the NB one right at the bottom of the image..... Strange as the rest of the image doesn't show misalignment or any of the usual suspects. ( asteroid??)

[Hagar]

Definitely an interesting target Fred. It looks more like the head and shoulders of a Hawk with the smaller beak, large eye socket and spread wings. Lovely detail. I now know why people like NB imaging.
Very nice

[Bassnut]

Thanks Guys. With large apature, this object has the ability to make a standout sureal image, one for another try in the future.

Clive. Some serious photoshoping on stars around that area due to utter frustration, the RGB star data was taken a long time ago and not too good.

Fred, the neb is 10.99 and it's 11.8' x 11.8' (538 x 538 light years) in size.

[Garyh]

ditch the stars Fred! ;) I think it would look even better that way!
