M27 in HST

[Dave Smith]

Last night was the fourth time that I have attempted to get some OIII and SII data on the Soul Nebula but was finding even after 20 min subs that basically there was none there. I have been blaming the haze for this, so in desperation swung round to M27 to see whether I could get some OIII and SII (and also Ha) from there. I was using the wrong scope for the object (Megrez72) and would rather have used my FL102S refractor or even my 9.25" SCT but I wasn't going to spend time changing scopes for something I expected to fail.

I was quite surprised with the results. There are 10 x 5 mins each of Ha and OIII and 10 x 10 min subs of SII.

The OIII was quite a bit stronger than the Ha and as expected the SII was weak but clearly there.

I am astonished that with the length of subs that I seem to have captured some of the outer shell (only in the Ha and OIII) so may have another crack at this with longer subs for the Ha and OIII.

I still do not understand why I'm getting nothing on the Soul Nebula as I have seen some nice hubble images on the web.

Very nice Dave would love to see some more if you do have another crack at it, can't help you on the Soul Nebula I'm afraid as I'm only just starting to get into imaging planets with a web cam but I love looking at the work you guys do, hope you get it sorted

Great Dave - The outer shell is starting to show very well in that image

[Dave Smith]

Thanks Robbie, I'm hoping to have another go tonight only this time with my FL102S refractor. Should give a better image scale.

Thank Francis - the daft thing I wasn't trying for it, I have tried before and failed. So I'll give it a go tonight - fingers crossed.

Very interesting Dave - few people seem to be able to catch the outer part

[x6gas]

Excellent result Dave and a fantastic achievement to get the outer halo... and with only 5 minute subs! I am jealous!

[Dave Smith]

Thanks Ian.

Here is my attempt using my FL102S. It is about 10 hours total over two nights with 800 sec subs of each nb.

Very nice shots there Dave. Looks like your last version has lost a little bit of central detail/contrast compared to the first though.

[Dave Smith]

Thanks Freddie - that is likely due to my hurried processing - I'll have another try

Dave

[Dave Smith]

I think this is better.

Dave

[Freddie]

Yep, the detail is back and an improvement on the original. Very nice. I really must find the time to process my data.

[Dave Smith]

Thanks Freddie - I needed that push
