NGC1935 a superhole nebula in the LMC

[gregbradley]

This was a recent diversion from a run of galaxy imaging which I am still in the middle of.

Superhole in the LMC. An interesting nebula with a wind blown section which creates interesting shapes.

A quick bicolour image. I took a lot more but it didn't get saved due to a full hard disk!

CDK17 and reducer at F4.5. Starlight Express Trius 694 and Astrodon 5nm Ha and O111 filters.

Hi Greg,

That's quite a nice image. When you say Bicolour, did you map the Ha to red, the OIII to green and blue?

It's a shame about your full hard disk, they're really quite cheap these days, sometimes I don't even bother to back them up, I just copy everything over to a new (much larger) disk and then install that. Using a Mac for imaging makes this a snap.

Good start on this one Greg. I did it a few years ago and found it a pain to process.

Cheers

Thats different Greg, trippy looking object, nice smooth result, dig the central cluster, like a mini rossette :P
Appreciate your captures you share here, very inspiring for many, im sure :thumbsup: Top show :thumbsup:

[gregbradley]

Ha to red O111 to blue and (Ha +O111)/2 to green.
Yes they are cheap but quite flimsy and easily fail.

Greg.



Thanks Steve. I'll take some more between galaxies! I think it also needs some decent seeing as its quite small.

Greg.



Thanks for that. It is quite unusual and I appreciate your encouraging words.

Some very cool structures there, Greg. Would be good to see with some more data. Shame you lost some.

[gregbradley]

Hopefully its up for a while and I can get some more data for it.

Greg.

[strongmanmike]

I like the colours Greg and with more data this will be a cracker! :thumbsup:

Actually I made a start on this too some time ago, at the end of a galaxy imaging run none the less ie a fill-in image :P....must go back and complete it.

Mike

[gregbradley]

Thanks Mike. Yes its a worthwhile target. I imaged it in Ha only a few years ago and always meant to come back to it. I think it needs decent seeing as well, so a night with good seeing and the moon up would be a good time.

Excellent work on this one Greg. Rarely imaged. Nice to see your touch on it.

Thanks John. I plan to do a more extensive image of it.

Great photo Greg.

Love the detail.

Ross.

[gregbradley]

Thanks Ross. These LMC nebulas are a rich source of imaging targets for us. I see a massive rise in the number of them being imaged now which is great. Hardly any were being imaged a year or two ago beyond the Tarantula or widefield images of the LMC.

Wow! Very very beautiful! I am trying LMC, now. Maybe I get something, but never will be similar.:eyepop:

[gregbradley]

Thanks Jorge. Its a very rich area for imaging these unusual nebulas.

Really weird shapes in that nebula! I like the colour mapping. I often find Ha to red and OIII to both blue and green works well, but it doesn't work in this case.

Thanks Geoff.

[Shiraz]

Nice work Greg - you are getting excellent results from that combo.

[gregbradley]

Thanks Ray. I'll shot some more with it and post a deeper shot soon.

Greg.

Unusual colors but amazing details Greg, you must have a very stable seeing to get these details at less than 0.5"/px sampling! Impressive..

Clear skies
Marco

[gregbradley]

Thanks Marco.

I've decided in the next moon period to do an LMC nebula's imaging spree! There are so many of these interesting nebs that are just within reach. Yes I was surprised at how sharp it was knowing how small it is.
Colour will be better on the next series - promise!

Greg.

[SkyViking]

Another great image of an unusual target, you're cranking them out Greg :) I'll look forward to your LMC nebula collection and maybe I should also have a go myself.

[gregbradley]

Thanks Rolf. There are quite a lot of these interesting LMC nebulas.

Greg.

[noeyedeer]

still looks amazing ... wonder how many new stars will form from it ..
nice work

matt

[gregbradley]

Thanks Matt. Its a pretty striking looking nebula. To look at it you'd have to think its forming quite a few stars.
