Cygnus HA 50mm widefield

[melsky]

Widefield shot of Cygnus through a hydrogen alpha filter, shot at the Rollright Stones last night at a Chipping Norton Amateur Astronomy Group observing evening.

A fantastic evening, we had eight scopes and two Astrotracs on the go, I also shot a time lapse but that will take a little longer to process.

Modded Canon 550D with a zuiko 50mm lens mounted on the astrotrac, this is a stack of 31 frames of 5 minute exposures at 800 iso all processing done in Photoshop.

Spot on ...really like that framing as all the major red stuff is included...

Like it- I presume this was a clip filter? Been toying withe idea of putting a 2" narrowband in front of a 50mm lens but I have no idea if this will work?

[Psychobilly]

I can't see why not..

Flats should sort out any vignetting but I wouldn't expect too much unless it's a fast 50 with a larger filter thread...

I think this is an absolute cracking picture. I love seeing the crescent nebula so small and incontext and there is just so much to look at. Well done - An inspiring shot.

Outrageously good. Just look at the Crescent hanging suspended in space. I'm always banging on about the advantage of mono for Ha but this is going to make me go quiet for a while!

Truly a masterly widefield.

Between the NAN and the bottom left hand corner of the image is a nebula consisting of two snaky bands either side of a bright star, which I think is 75 Cygni.

It's a little smaller than the NAN but I can't see it on SkyMap. Do you know if it has a name? I reckon it needs attention from telescopes, whatever it is.

Thank Olly, I feel I'm starting to get the hang of using the Ha CLS clip filter I think the key is the Photoshop Raw file conversion before stacking.

As to the nebula in the bottom left hand corner I'm afraid I have no idea.

Cheers Mel

Well spotted Olly, this clearly needs more attention by imagers - I guess it's just too close to other 'juicier' targets.

I checked my widefield colour version of this area and it can also be seen- so it's not that faint.

Well I have one word - stunning

Congrats Mel I wouldn't have thought an image of this quality would be possible with a humble DSLR

[Nightfly]

Extremely good work. So wonderful to see. You are getting all that little 50mm will deliver I think. Top marks Mel!

[Shibby]

Cor blimey. 'Nuff said I think!

[Coco]

Well done Mel, thats one hell of an image, I could look at it for hours!

[MidnightSun]

Just Wow.......cracking, as they say.......Awesome.

[fwm891]

Superb image Mel, One hell of a lot in there - inspired!

[MartinB]

Phenomenal. Well that's inspired me to put my Ha clip filter to use. What F ratio were you using?

[Martin-Devon]

A really outstanding image - maybe you could tag names to all the nebulae etc etc in there - would make quite a list!

[george7378]

That is perfect - is that the Jellyfish nebula to the right of centre, or is it another nebula?

Excellent Mel
