I took this a while ago. Lots of cloudy/rainy weather in the Sydney area in Jan so not much chance to do more on this.

This one of the nicer nebs in the Orion area.

Utterly delightful image Mr Bradley.
I tip my hat to you.

Unbelievably smooth and sharp, well done!

some thing that the Hubble would take

Wow, thank you. I am glad you liked it.

Thanks. I think there was some good seeing on some nights as well.

Very nice for what is a relatively short integration on a difficult object, Greg

The fast scope certainly performs as you would hope.

A minor nit is that at full res there's a speckly effect visible in some areas, maybe sharpened noise?

Cheers,
Rick.

marc4darkskies (Marcus) · #8 16-02-2016, 08:17 AM

Agree with Rick. You need to blur the colour layer before sharpening the image Greg. This is a dim and difficult target so you probably need more data too. Also noticing some lobes on your stars at the 12 o'clock position. Did you have a guiding issue?

strongmanmike (Michael) · #9 16-02-2016, 10:26 AM

Not bad, I like the colours and certainly some good potential in that image Greg

. I'm thinking though it may just have needed some more time? Also, while not a biggy, the stars look kinda rough and wobbly, is that from your star shrinking process perhaps?

Have you taken the RHA to Bigga yet?

Very nice.
I also notice the minor grainy effect in the larger image.

Would be an absolute winner with more data I think Greg. While it looks good in the small size it's quite noisy in the larger size.

More data would help. I'll try to get some more.

The subs seemed pretty good but I have noticed that I do get some slightly eggy stars when the scope is on the east side and when on the west side they are perfect. Trying to track that down. Suggestions?

Yep needs more time. No work done to the stars pehaps the issue mentioned above. Yep I have taken the RHA to Bigga. Probably will do again in the near future now the weather is drying up a bit.

Thanks Steve. I'll add some more data to it. I was planning to but ended up processing it as it is for now. I do like the way the image is turning out so its worth some extra effort.

Greg.

gregbradley · #13 16-02-2016, 06:06 PM

I fixed the noise. The stars issue is pretty minor so I'll leave that for now.

Greg.

looks great Greg, nice to see an image from you again - it feels like a while!

DJT (David) · #15 16-02-2016, 08:58 PM

Lovely image Greg.Interesting area to play in.

Thanks Russell. Yes it has been a while. I've been consumed with a contract I had to deliver plus its rained a lot. I have several images unprocessed yet that I have now got the bug to process and publish though.

I did this one years ago but not a lot of time spent on it and I was happy with it. Its an interesting object.

Peter Ward · #17 16-02-2016, 09:29 PM

I'd only echo the quibbles posted earlier, that said, a good rendition of a tough target.

P.S.
Sadly my RHA is now back in its box... I'm enamoured with the new German girl.

So shallow of me

Thanks Peter. You have 2 superb choices there in equipment.

Very nice Greg, lovely blue colour

Paul Haese · #20 17-02-2016, 11:45 AM

Some nice colours and detail there Greg. Maybe a little dark though.
