Here are some more (including a further enhanced version of the Lagoon one):

M20 & M8 (Lagoon and Trifid):

Milky Way (bit of interference from light clouds):

Snake Nebula and region:

Blue Horsehead:

Eagle and Omega (Swan) Nebulas (M16 and M17):

Also reprocessed my old Andromeda data, whole new (and much more realistic) look:

A guy on Cloudy Nights shared his Trifid data, which turned out to be pretty good:

And my latest, Veil Nebula, which is still a WIP...only got half the data I wanted, plus there were light high clouds moving earlier in the night that left brown muck throughout a lot of the field:


WOW, WOW, WOW, WOW, WOW, WOW, WOW, and WOW

These are inspirational!!!!!

Fantastic!!!!!!!

Thanks, Guys! :) Hopefully that won't be the last this year...weather has been pretty wild, never know when the night might clear. I've even missed a couple because I thought it was going to be cloudy, and early when I poked my head out it was...only to have it clear later on after I'd mostly gone to bed (and at that point, I can't go out and set up...not on weekdays.)

While you can barely fit a 600/4L and 5D III on the Star Adventurer, it is not recommended. The rule of thumb for imaging is to use only half the rated capacity. More than that, and your tracking accuracy will suffer, which will affect your stars. You shouldn't put more than 5-6 lb on the Star Adventurer for best results. You might get away with 7-8lb, but with longer lenses your star profiles will suffer (you'll have bloated stars, and you'll lose the benefits of the increased resolution of a large lens like the 600mm f/4).



I'm sorry to be asking this... so is the Star Adventurar an extremely well designed barn door tracker? I mean, you can't track the stars in exposures longer than 2-5 minutes @ 200mm or something like 30 seconds on 600mm, correct?

The Star Adventurer with the Equatorial Wedge tracks right ascension in sidereal time, so it is definitely not just a glorified barn door. It would be a full equatorial, albeit without any powered DEC tracking (so it will only track in RA, and DEC pointing is manual.)

With an appropriate payload, and good polar alignment, you should be able to track for minutes. With wider field lenses, including a 200mm, you could probably track for 10 minutes, but you really wouldn't need to (the wide lenses suck in a lot of light per pixel.)

Here's another one. This time, the Gamma Cygni region:



Very complex region, lots of emission nebula (both hydrogen and oxygen), lots of reflection nebula, lots of dark nebula. Star clusters. This one was a tough process.  Little bit less than three hours integration time.

These could just be the most stunning images I've ever seen on Canon Rumors.....and I've seen some brilliant work on Canon Rumors.

Great stuff, Jon. Please keep the images coming :)

Thank, Click! Thanks, V8, truly.

I'll keep em comin if I can get em. Weather in Colorado has been really bad this year. Hardly had any clear nights. Been trying through the couple of clear nights we have recently had, but they were riddled with smoke that blew in from California, so still nothing. Now the moon is full, so it will be a couple more weeks before I even potentially get another chance, if the skies are clear (which is unlikely.)
