For some reason this didn't come through the first time I tried. If it did,
sorry about that. Hi all: I took this image last night from the LAS observatory before the clouds rolled in. Hutech Canon T1i 1x3-minute exposure, dark subtracted, gradient removed with GradientXterminator, levels and contrast adjusted in Photoshop CS3 Konus 200 mm Losmandy G-11 Gemini, autoguided I'm slowly getting better at this.

George Keep up the good work George. I ran a very similar setup. I'm living vicariously through your efforts. High end results from folks like Rick et al, are awesome, but those earliest results from budding astro-imagers have a different feel to them. A raw pioneering dedication that ends in the thrill of first results. Results by the way which are better than the professionals could get just a few decades ago. -- Steve Paul |

No way around it. Digital technology plus today's mounts make it far easier than it was in the 50's when I started down this road. George's images are better than I could get for many years. I started with a camera on a two hinge barn door platform run by a wind up alarm clock. You had to invent your own gear back then. Later I moved to AC motors which were a pain in the field as you had to control the frequency very precisely, temperature falling made that "interesting". Mounts without PEC and with far more PE than today's mounts have before PEC and guided manually kept you glued to the eyepiece for hours at a time while you froze from inactivity. Only a couple negatives could be stacked in the enlarger before no light got through. So you used 2 hour exposures and at the 1:50 mark you were dead tired and suddenly hit east when you meant west to make a correction and all was ruined. Or the neighbor kid leaned against the scope and asked; "whatcha doin'?" I saved his life by not killing him. Those were the "good ol' days" today's imagers, fortunately, don't have to endure. Today the skills learned on simple equipment will pay big dividends as better gear can be afforded. When I started I had no hope of ever taking images like I can as the needed equipment literally cost millions of dollars. Now it costs no more than a basic new car. So it comes down to, do I survive with one car and a good imaging set up or continue with my simple stuff and have the convenience of another car? Once the kids were out of the house I chose the former, sort of, I bought a $1000 245,000 mile pickup, That's the cost after I rebuilt the engine and manual transmission. All those years of film work made the transition rather easy. Well not the change to digital darkroom, I'm still climbing that learning curve. I do miss the fun of concocting new developers and dark room techniques but not getting sick from the fumes even with a good exhaust fan. Or the stained fingers I always had because I just had to touch the prints rather than use tongs like a sane person would. Rick Rick -- Correct domain name is arvig and it is net not com.

I would not call someone with an autoguided G11 a "beginner". I started with a manual guided scope and a self-modified webcam, imaging planets and the moon..... I like your M3 george, good work. -- Martijn www.xs4all.nl/~martlian |

Or the stained fingers I always had because I just had to touch the prints rather than use tongs like a sane person would. Thanks for sharing that. Sounds like you really had to pay your dues. I'm one of the "lucky" ones who walked into imaging with a large enough fistful of dollars to afford modest beginnings, and enough experience with observing gear to have a good idea how to get results. A G-11, DSCs, ST-4, DSLR w/Bulb Timer-Controller, and a short rack of 25AH SLA 12V batteries. I initially tried using a laptop at the scope, but it didn't take long before I was using the standalone ST-4 and the TC for subframe collecting on the interal memory card. I really liked that setup. Probably more work to actually aquire a guide star and the target, but not having a computer at the scope is a huge boon for those of us without a permanent setup in a roll-off or dome. I'd roll the entire setup from the garage, out and around to the south facing backard on a ScopeBuggy, get polar aligned, setup a shot, fire off the timer controller, then go observe stuff with my Dob while listening for the shutter clicks to stop. Then I'd pop out the memory card, go into the house through the ground floor slider which opens into the den, and check the immediate results on the computer. Once I got pretty proficient at it, I stopped checking the results until the night was over, which kept me from losing my dark adaptation for observing with the Dob. Made for an enjoyable evening on the too rare occasions when skies and temperatures (read that, bugs) were cooperating, and gave me some data to play with at the computer on the nights when I didn't want to be outside. I managed to inadvertantly capture a before and after of the SN in M51 from my driveway out front, whenever that was some years ago. Wish I had realized it before I heard about it on the internet. Still, I was pretty thrilled to see that I had captured the B&A of that. The images aren't great, but it does prove that great images aren't needed to capture significant events, and that can be fun in and of itself. Haven't been keeping abreast of recent developments, but I think it would be great to have a true astro CCD imager with internal memory card and an exposure timer-controller like the one I had for my Canon 300D (TC-80?) so you could operate untethered from AC power and computer. -- Steve Paul |
