Pillars of Creation

This is just a tight crop of the original data so far, need to retake some calibration frames to fix up some banding issues that present themselves when stretching a bit harder. So, tight crop on very high signal area

Although it doesn't really present itself this cropped I am still trying to find out where I am getting some tilt in my new imaging train. So far I know that it isn't the focuser, the connection between focuser and CFW which leads me to one of a couple of connections between CFW and QHY163M OR the sensor itself. More testing to hopefully be done Wednesday night
To top it off, my sensor to rear corrector is a bit out of whack. It is a few mm off of what I was expecting from the parts description so I'll have to track that down.

Now that the rant is out of the way I am actually really happy with the results, the heavily cropped part anyway Well, except for the JPEG compression

Looks good to me Colin. Maybe this time next year I'll be doing something similar.

Hi Colin,

Very nice sharp pillars!

.....Very nice.

I'm not a fan of narrowband data pink stars, so my taste would be to remove them and use RGB star data or at least turn em white....??!!, but that's just me.

Well done.
I hope you can chase down the tilt problems you describe....can be a pain!
Cheers,
Tim

Nice one Col, the pillars are a favourite and I really like the colours you show here and you have some of the famous little details there too. While I actually like the look of slightly magenta stars sprinkled across NB mages, I do agree with Tim in this case, as they currently look a bit prominent, possibly some miss rego there too?

I agree! Some of them stars are really distracting! I just spent 15 minutes this afternoon having a play with one of my favourite regions to see how it would turn out. SO much better than my last attempt last year!

Will try to add some synthetic RGB stars when I go for a full process. I have did bias frames at the moment, they're suffering from some unwanted banding which is apparently caused by the settings I had and a conflict with the 128MB buffer on camera. Only effected my bias frames but that then kills my flats which then causes gradients I cannot remove

Thanks Willik, actually easier processing this little crop compared to the entire image; far smaller dynamic range to deal with.

I'm not a huge fan of the magenta stars unless they're understated; like what Mike"(s) can achieve. Going to reprocess once I get my calibration frames sorted, really need to drizzle integrate it.

Some of the tilt is field curvature due to spacing issues. I thought there was going to be a 1mm difference between the QHY163 and ASI1600, something that can be compensated with the FLI PDF. Turns out to be a lot more than that with my current adapters.

Hi Col

Really nice image. You have the colours just about spot when comparing to the Hubble image. Very impressed.

Well done

Looks good Colin, apart from the stars Lots of detail with the reluctant parachutist showing up nicely.

I wouldn't dare compare it to a Sidonio! 12" beats a 5" and his seeing is nicer

Thanks, I used a Hubble image as my colour template. In saying that, some Hubble images are redder than others which makes it difficult.

Stars are horrid I know More detail than I was expecting from a lowly 5".

Great image Colin, I can make out the gas jets on top of the pillars, do you have a larger version?
Not sure about those pink/magenta stars

That's the plan. I want some cooled narrow band / deeper LRGB action and the only way I'm going to get that is with a mono CCD/CMOS of some sort. Eyeing the ZWO ASI 1600mm-c at this stage.

This is currently full resolution, until I recalibrate and do a 2x2 or 3x3 drizzle anyway. Just need to retake my Bias frames. Stars are on my To-Do list! Maybe I'll just remove them entirely! No comments then!!!

Small scopes can do very well, Suavi has done a lot with a modest 4"

Shiraz has the closest setup to what you're proposing and he's got some fantastic images out of it. You'll have a lot less noise than you're getting with your DSLR.

Nice one Colin, great start for the new cam. I do like the images where the pillars are leaping forwards on a prey, but I know this is just a test.

Yes, looks great ,Colin. I like that you captured blue streamers radiating away from the 'top' of the 'main' pillar

Apart from the magenta stars which I find terribly distracting that's a very nice shot of the pillars Colin.

Cheers

Love the colour palette & great detail - but can't get past those flouro disco purple Prince stars!
If you can you dial the saturation in them down say 500%, I think you have a ripper of an image in the making
