 Thanks Jrista for starting this thread it made finally get started setting my stuff back up. I haven't set my mount up in 4 years, moved and a permanent setup has always been on the to do list (but at the bottom). The long 4th weekend gave me time to unpack and setup temporally to tryout were I might want a permanent mounting. This is a wide field (about 75% crop) of the area around the Trfid and Lagoon nebulae. This is about the southern edge of my usable sky were I have it now. 84 frames at 800 iso, 30sec , 300 2.8l is , 5DIII, on an Atlus EQ-G processed with Images Plus. Alignment needs work but it has mostly been cloudy since.

 Thanks traingineer,
           I have alot of projects planed for this combo ( 5DIII and 300) , My favoite night sky is now though January.

You are welcome! I'm glad your participating. Your image is excellent! I've tried to image that target a couple times myself, but my view of the southern sky from my back yard is nearly completely blocked, and I have never been able to get the necessary subs. Your detail and color are great for 30-second subs, too! The f/2.8 aperture must be a DREAM! :D



Here is one of my latest. This time, it's Crescent nebula...also, as you might have guessed, in Cygnus. Cygnus is moving along pretty early on in the night now, crossing the meridian by about 11pm now, so unless I can figure out how to get some good imaging time on Tulip and/or Propeller nebulas (both also in the Cygnus molecular clouds), I may switch to a different target soon.

This image took a LOT of work. I've had to fight some technical issues with my tracking, which was actually caused by a few different things combined into one hellish problem. I also had persistent weather (it's been a COLD summer...temperatures are often in the 70's or below for days at a time, even as long as a week once...when usually we have temperatures in the mid to high 90's with more than a handful of days over 100), which has cut out a LOT of sky time.

Anyway, persistence finally paid off, allowing me to image Crescent Nebula, which itself is pretty well known...but also pull in a lot of the background nebulosity detail from the extensive molecular cloud in the Cygnus region of one of our galactic arms:



The Crescent itself is quite complex, and actually has a very faint outer shell of mostly oxygen-based gasses that glows a faint blue (usually too dim for a DSLR to see, and generally requires some deep OIII narrow band exposure to bring it out...but I managed to reveal a little bit of it here):

Nice... Proof that you don't need insane amounts of gear to get started....

Definitely deep sky. Nice results for a single shot. Especially only FIVE SECONDS! :D Well done.

Elephant Trunk Nebula

Managed to rip this one out relatively quickly, compared to how long it usually takes me. Thanks to a several-day break in the weather, I imaged all night for three nights in a row, gathered 130 subs, and integrated 116 of them (nearly 10 hours of exposure time).



My deepest exposure yet, by a long shot. Elephant Trunk is a very faint nebula, compared to most of the ones I've been imaging lately. So it needed more exposure time than normal (I usually get 30-50 subs, maybe 4-5 hours, sometimes a little more than that.) I'm pretty happy at how the dust lanes came out...I usually barely get any of that.

Thanks, guys. :) Glad you like. One of my best so far. Data on that one was so good.

I'm trying a new technique. I used an Astronomik CLS filter most of the year, but it is making it really hard to get images quickly. I have so few clear nights, and I need to image for several nights to get enough subs to produce the kind of quality I got in the Elephant Trunk...that I'm trying to image without the CLS filter now. It results in more complex work in post, but...if you can work through it, you get stuff like this:



Compare that to my first two attempts at Pleiades from the original post of this thread. :D One thing I really do love about the 5D III? It's huge full frame...has a really wide field, which is just awesome for images like this.

Beautiful!!!  Been a fan of your shots Jrista.  Can you tell me any starting cheap kit I can use for Astrophotography?  Right now, I have some cheap but decent long lenses like 100mm F2.8 Macro, 70-300mm IS USM.  For starters, do I need to buy more?  Thanks!  BTW, I'm using Canon 6D.
