Canon T5i (modified), Canon 300mm f2.8is II, Astronomik Light Pollution Filter, f2.8, 90 second exposure (36 exposures for 54 min total), Astrotrac Tracking Mount, Light, Dark, Bias and Flat Frames stacked in ImagesPlus with final edits in Photoshop and Lightroom.
Please view in shadowbox. Well, the astro-bug has bitten me, and since photographing the Rosette Nebula I decided to make a couple of upgrades to my kit. The keeper rate of long exposure big lens tracking with the Sky-Watcher was frustratingly low. With so few dark clear nights I decided that I wanted something more reliable. I ended up springing for an Astrotrac, which in every way is superior to the Sky-Watcher. At 3x the price, it should be. Tracking was perfect on 90 second exposures with a 300 f2.8. I also decided that I wanted to modify a camera by having the IR filter removed to make it more sensitive to the hydrogen alpha emission lines of emission nebula. Not wanting to modify my brand new "wildlife" camera I decided to purchase a T5i and sent it off to Hap Griffin for the mod. A few weeks ago I photographed the Horsehead and Flame Nebula, but was not really too pleased with the results. With my new gear I decided to take another crack at it. Being so late in the season for shooting objects in Orion Constellation (and with an obstructed view of the southern sky from my location) I wasn't able to get as much integration time as I would have liked. I really wanted double the exposure time, but I had to settle for this until next winter. Chris White
