Equipment
Stuff I own now...

This allows me - and it's trickier than it may seem at first - to collect twice the data in the same amount of time. For my nightscape photography, I use a couple of Canon 5D Mk2's, but not in parallel :-)
More specifically, this is what I use/have at this moment:
- Takahashi EM-400 mount (love it!).
- Takahashi EM-200 mount (love it as well! This one's in Spain, so I can also do some astrophotography when I travel there).
- 2 x Takahashi FSQ-106 EDX refractors (a perfect match for the STL11k CCD).
- 2 Orion ShortTubes 80mm for guiding - one here in the US and one in Spain (why travel with a guidescope when you can just have one "there"?)
- 2 x SBIG STL-11000 Monochrome CCD cameras with 1st gen Astrodon LRGB + Ha filters.
- 2 x Canon EOS 5D Mark II. The Mk2 is an amazing DSLR camera. My workhorses for night-time photography.
- Canon EOS 40D IR/UV filter - also mainly for night-time photography.
- 2 x Orion StarShoot AutoGuider guiding CCDs.
- Assorted Canon and Sigma lenses, from 10mm to 200mm (primes, telephoto, etc)
I also have a load of accessories such as the two Takahashi focal reducers I mentioned earlier, or the extender for the FSQ, a FlipFlat (to generate flat field images), a TAKometer (to control camera angle from the computer), a TeleVue Powermate x4 I barely use, two RoboFocus focusers, a Moonlite electronic focuser also sitting on a shelf, a whole bunch of eyepieces, dozens of adapters of all sizes and colors (well, they're almost all black :-), and a long etc of "stuff"...
If I were to include EVERYTHING I take with me to an imaging session I'd also have to include my HP Beat laptop, five deep-cycle marine batteries (to power up laptop, mount, cameras, robofocus, etc), two battery packs (I use them only in case of emergency or for other stuff non-astro related while I'm out on a hilltop or camping), portable chair/table, a pair of binoculars, a green laser pointer that I practically never use, miscellaneous camping stuff - including a large tent/canopy - and some other "utility" gear as I call it. Oh, and hundreds of cables, adapters and what not.
Also, my good old 2006 Acura MDX played a huge role in my astro outings, of course - having driven well over 60,000 miles just going places to do astrophotography. The MDX however was totaled after I ran into a poor deer in a fast highway late August 2012. The car had almost 130,000 miles when that happened, but I'm sure it could have gone to another 130k if this unfortunate incident never happened. I came out okay from the accident by the way, although the poor deer didn't make it... Neither my car. The replacement was a 2009 Honda Pilot Touring that I've got in January 2013 which so far has been behaving like a champ.

More of the same, here at Henry Coe State Park, also in 2009. This is the equipment that has produced almost all of my most popular images up to 2013 (after that, I doubled it :-)
