Everyone guided by eye and hand, and shot emulsion-based photograpy. It only seems monumental when one has the less-strenuous digital option available. BTW, when the very first imaging CCD's were used for astronomy, the hardware consisted of a single-line of sensors, not a grid. The image drifted across the line, which was really a type of scan. And sensitivity was terrible. Only bright objects could be imaged, and the resulting image looked more like a cartoon or painting than a photo. Images contained very little data compared to today's. Amateurs living today are extremely fortunate to have such capabilities available to anyone who is willing to spend the money on the equipment. It was not always so- well within living memory. --- Tyler Allred <tylerallred@earthlink.net> wrote:
A bit taxing!!!! You are a more dedicated soul than me! :) I prefer CCD and autoguiding, thank you.

Tyler, I did not mean to marginalize your astro-imaging efforts. The results are certainly top-notch. I just wanted to point-out that it is now in fact easier to do astrophotography than it once was, to a much higher standard- and consumer choices are much better and more affordable, in todays dollars. By your own posting, it read like you probably would not be doing it (or at least not be as productive) if you had to guide manually for the same exposure times and deal with emulsions instead of digital files. Did I misinterpret your statement? Anyway, I'm very sorry if I offended you. I know how difficult it can be to become profficient using certain software and manipulating data- I recently took a college course for a year to get a Solidworks certification (3D design/drafting/manufacturing). And there are still times when I have to dive back into the manuals or the help files! Sounds like you've been involved nearly as long as I have. I am almost 48, and have been doing this since I was nine or ten years old. I had found all my Messier objects as a ten year old, by myself, with an Edmund 4.25" reflector. What a ride it's been. --- Tyler Allred <tylerallred@earthlink.net> wrote:
