Triffid nebula (M20) from Salisbury

[Tim]

This was the target I really wanted whilst at the SP, as it is never visible from home. Sadly I only managed to get 9 x 600 secs in Ha, and just 3 x 180 secs with a broadband blue filter, and even then the light cloud had drifted across. So here is the Ha version, and an rgb that has been cobbled together with fake green, weak blue and ha for red.

I was amazed to see that even 3 sec frame and focus exposures were showing the Ha part of the triffid clearly on screen, even with the 7nm Ha filter in place, and also that the whole region is simply swimming in Ha emissions.

So this little taster has really whet my appetite to do this one properly sometime, but it will take some planning.

Thanks for looking.

Excellent detail in the H2 emission region Tim, but I think, as you have laready hinted at, the reflection nebula (blue region) is going to take a bit more action. Many of the narrowband images of this object concentrate on the emission portion only. I guess this one could potentially be a very long project with it having such a southern position.

Well captured, Tim, you should be pleased with that one.

Looking pretty good in Ha but as you have said a revisit needed for the rest of the data

Nice image Tim, loads of detail in the Ha areas.

Good! The Ha has done really well. The blue is always relatively faint and often needs a push.

Wow - I remember seeing this in the caravan and wondered when it might appear on SGL - it's a really sweet image Tim - nice one
