Seriously, so I could get an 8" Newt on an AZEQ6 and get results like this with a DSLR?! If so then why does everyone say to get a 10x more expensive ED80/120 APO and guiding camera/scope for another $500 on top instead?!

Hi Cody, mount was an HEQ5 pro. Subs were unguided. On the plus side, at the time of taking this image M42 was near the meridian. My sky in that direction is fairly dark in spite of having many street lights to the west. On the minus side, air temp was very warm, near 30C adding some noise to the subs. I used flat frames but not dark frames for this image. I also used a Baader UV / IR cut filter inline. It can help cut through haze a little better. The Pentax K-5 is an off the shelf unmodified camera with no cooling.
I also have an ED100 Refractor. It will do a similar job but take longer to do it. Fast fat Newts are a good combination with a DSLR.
I haven't set the guidescope up on the Newt yet. Not much point in summer as longer subs just get noisy from the heat. I might get around to it when the weather is cooler and I want to go deeper.
