Like a frikkin' cosmic fireball streaking thru the heavens! that's AMAZING!

Think Lewis' reaction is also how I'm feeling about this one - crikey!

Bravo!

I formally crown you processing King of Australasia!

That must've been a hell of a lot of work. Do you use Registar to get them all the same alignment or is there some routine in PI that does it?

Greg.

That is an impressive result for a little imaged peculiar nebula with dust reflection etc.

John.

Ta, Kevin. Look forward to yours!

Thanks, Greg. I don't think the crown would rest easy

The combination part wasn't too tough. I used PI StarAlignment for the registration and GradientMergeMosaic to combine the images. The only tough part was the RCOS data which had a much hotter background and wouldn't blend nicely. I had to clip it to an elliptical mask and do some fancy feathering in PixelMath.

Rick,
That's fairdinkum unreal,
Technically speaking it looks like a fox wearing a blue diamond cravat!

Seriously never seen this sort of cosmic spleandour, well done!!

Excellent Rick

Thanks, Louie!

Exquisite work Rick. Your collaborators should definitely feel they got value from that image

Star Catcher (Ted Dobosz) · #30 25-03-2018, 08:26 PM

What a great looking result from this collaboration! Well done all.

I keep coming back to this image.

And I keep whacking my chin. Must remember to put some padding on my computer table.

I wonder if my FSQ85 could reach this level of perfection in 4 years (of continuous imaging)

RickS (Rick) · #33 27-03-2018, 11:52 AM

Thanks, Lewis. A four year capture with the FSQ85 would do an amazing job of the dust around 1333. I'd love to see that

Jeff · #34 27-03-2018, 12:33 PM

Fascinating image Rick. Must be bushfire season up in Perseus. So much to look at in the full resolution version which is stunning.

RickS (Rick) · #35 27-03-2018, 12:59 PM

Thanks, Jeff. Yep, an amazing amount of stuff happening in that field!

strongmanmike (Michael) · #36 07-04-2018, 11:20 PM

Just having another look at this Rick...its a really interesting bit of sky...almost unique..? Anyway, again, very nice

Mike

RickS (Rick) · #37 08-04-2018, 07:47 AM

It is a pretty special FOV, thanks Mike. Shame it doesn't have a couple of big, interacting galaxies too

vlazg (George) · #38 08-04-2018, 08:38 AM

Hi Rick, I keep coming back to this image, stunning.

alistairsam · #39 08-04-2018, 01:24 PM

Thats stunningly beautiful Rick, awesome processing.

between the 20hr, 40hr, and 50hr data sets, did you see much of a difference with additional data, if so in which features?

Cheers,
Alistair

Thanks, Al.

The data sets from the C300 at SRO and TEC 160FL at DSW were at roughly similar image scale and provided the full FOV. They were not too different in overall SNR (17x1200s Lum for the C300 and 31x900s Lum for the TEC.) Combining them made a nice improvement but not dramatic. You can get an idea of what the TEC data by itself looks like from the image that Alberto Pisabarro created from it:

https://www.astrobin.com/339138/0/

He processed it very well but the outer areas of my version do benefit from the extra integration time added by the SRO data.

The RCOS data from DSW was from a smaller, high res FOV. It was combined 1:1 with the other data drizzled x2 and only overlaps an oval area in the centre of the image. You might be able to notice a couple of 8-pointed diffraction patterns

The RCOS data has significantly better detail. It didn't do anything for SNR (since I dropped back the contribution from the other data in this area) but it did tighten up the central features remarkably well.

Hope that helps... I'm doing another of these images right now for M51. Perhaps I'll post some of the partial results and describe the process if people are interested. It's always a bit of an exploration. The data tells you what to do if you listen carefully

Cheers,
Rick.
