Ivo... thanks for looking at my images. Imaging on Kitt Peak has its limitations. No guiding for one thing. Most of those images where taken for clients that rent a scope for the night at the Visitor Center. I ran the scope and camera fo them. Even though they have the scope all night, they expect to see 30 or more objects and image at least half of those. So there is not time to set up guiding with the equipment we had available. That is why most exposures are around 2 minutes and there are often not more than 10 frames. Some of the client images were from single 2 minute images.....no stacking. See some examples here: http://www.geoandpat...o_canon_6D.html Maybe that is what the future hold! No calibration and no stacking.
You're doing great work - enthusing people for the night sky; that's where it all begins!
We clearly have the same goals here; I'm just really concerned with *keeping* people enthused as they start and progress in the hobby. With the right know-how, your guests can produce similar results from their (moderately) light polluted back yards with a cheap Canon T3 / 1100D. These are exciting times for AP and the barrier to entry has never been lower.
