SH2-126 The Great Nebula in Lacerta - Samyang135ASI2600mc Askar200QHY600

[Laurin Dave]

SH2-126 The Great Nebula in Lacerta.  8 hours each of Samyang135ASI2600mc  colour data and Askar200QHY600 Ha data.  Data capture started in  January with another short session in mid July and finally 5 hours last night. Processed using Pixinsight, Photoshop and Russ Cronan's  Star and Noise Exterminators.  Presented at 75pc 

Thanks for looking 

Dave

Top job, one of those large “off the beaten track” galactic nebulae done very well! Are you looking for other neglected sharpless objects?

Beatiful shot

Great image Dave, I must try this one out with the RASA8.

Thanks Peter... as for other Sharpless objects, not especially, I started this back in January whilst waiting for Orion to clear the roof tops as an experiment with the Samyang...

Thanks Peter...  one for Pier 5 perhaps?

Already collecting data on this with the Epsilon130ed 6200mm pro mono rig, it fits the FOV much better with this object, not a wide as yours but wide enough

Nice job!

Last night I needed a target away from the encroaching low cloud so I centred the RASA8 on SH2-126. They don't call it the Great Nebula in Lacerta for nothing, the QHY268c FOV is nowhere near big enough for this one, and being set up for broadband imaging all I got was the knot of (IFN?) nebulosity which I have given the label the Axolotl Nebula. My broadband SY135 rig subs were plagued with cloud, so not much available from them, this exercise has made me realise how much effort goes into imaging this target.

A great image and you captured it all Dave! Not often seen. I would be tempted to reduce the star field even more with the new XT tools - there is a lot of nebulosity and dust there.

Thanks Goran... I left them like that as they go some way to distracting from the messy background!

Having reflected on @gorann 's comment I've done a re-process, less emphasis on the stars and more on the Ha nebulosity... I think its a bit better.

I like the new version, which more clearly shows the nebulosity. The background still looks quite nice. This is a very odd lump of Ha, as @tomato just pointed out in his version.

[tomato]

Yes, the deeper you go the stranger it gets, fascinating.

[ollypenrice]

Great stuff. I'm a fan of this target, for sure.
