Given that the weather doesn't look like it's going to cooperate in the near future I thought I would post my latest HaOIIIOIII of Eta Carinae. There's only 105 minutes of OIII which isn't really enough I guess but the overall result seemed okay. Once again I used the AO-X for the OIII. Still learning about the settings to use with it.
Hmm?. well, I'll refrain from using any pretentious latin aka BS... and just say, very nice result Steve with some really good resolution there I get the impression you were having some guiding/star shape issues previously, has the AOX improved things for you?

Thanks Mike. I have had troubles with star shapes and guiding as I think everyone does from time to time. This is only the second time I've used the AO-X, both times on Eta Carinae, so given that I think this is the sharpest Eta I've ever done I think you could say the AO-X has improved things. I don't think it's a uniform cure-all though.

Thanks Greg. It turned out well given the small amount of OIII. Maybe I'll get some SII too if I can.

How will I ever be able to post another picture?

Thanks Allan. Honestly I don't think it's as good as you say it is.

Tip o' the hat Steve....the superb resolution in this effort is a new benchmark.
Well done!
Thanks Peter. I must admit I'm a bit surprised at the extravagant praise as I think there are better etas than this out there. Jay Gabany's shot with a 12.5" RC for example.

OK ...Jay's effort is more colourful...but those teeny stars in your image are remarkable!
I never got them quite that tight in my long focal length shot of the same region ...albeit some years ago now.
Suffice to say you've given me real motivation for a high-res Eta revisit when my new RC turns up later this year
As Peter stated those stars are tight.
Wonderful processing.
Cheers,
Justin.
Thanks Justin. I think it's all down to the AO

AO really does work!
Yes I'm certainly sold on it but this is only one object. It's also narrow band which usually means smaller stars. The test will be to try AO on something else. You do need pretty healthy guide stars for best results.
