SH2-308 The Dolphin Nebula

[Paul Haese]

I think I preferred the original image Greg. The palette looked better to me. It's a target I really need to have a go at. Do you have the RA and Dec for it?

Lovely stuff, Greg. Very blue.

I actually prefer your original processing. It's quite compelling and I particularly like the structure visible in the fainter extents.

I'll be honest though and say that the reprocessed version seems to have obliterated the structure in those fainter extents. Colours notwithstanding, the reprocessed version would benefit greatly if you could restore that structural detail.

Cheers, Marcus

That's fine Marcus I feel the same way myself. I think I will reprocess this from the ground up and see if I can get a better version of the first. It has been a bear to process.

I agree Paul. I will yet again repro this one. I did do a similar version to the first the other night but the star blend was off. I'll get there!

I find myself coming back to this Greg as I feel that the original image has a lot going for it. It has certainly generated a lot of discussion to be sure. Whilst I agree that the stars have been pushed the detail in the nebula and the structures revealed are amazing. You have inspired me to add this one to my hit list.

Thanks Pete. Yes the first was the better image overall for detail and extent of the nebula.

I haven't given up reprocessing this one yet. I may be able to get the best of both worlds on this one still.

Greg.

Very impressive indeed. Images like these rival multi metre diameter professional observatory scope not that long ago.
The tilt you mention must only be those slightly larger stars at extreme bottom right? Barely noticeable. With my Baader MPCC coma corrector ( old mk1) any tilt results in elongated or comatic stars not just larger stars. Larger format cameras sure are unforgiving but nice to have

Thanks for the compliments Scott.
That tilt was corrected at some point.
As I recall its only some of the exposures that have it.
I have tilt pretty much under control in my scopes.

Wow!
A spectacular rendition of a very difficult target!
Well done Greg!

Thanks Tim. A tough one to process for sure. I have spent a large amount of time and many variations on this one. More data when it comes around again in about 4 months?

Yeah, it is a wet season target for me, so I've never had clear enough skies to attempt it
