New Takes in Digital Single- Lens-Reflex (DSLR) Imaging

摘要

There are some who believe that DSLRs are a low-cost introduction to astrophotography that allows them to graduate to dedicated thermally cooled astrophotography cameras. This statement is true but is perhaps not the whole picture. I am a firm believer in the journey being as important as the destination, so even though I have both QSI and SBIG cameras, I still very much cherish and regularly use my Canon DSLR. When I image at a dark site, it is typically a significant investment in time and money to get there, so I want to maximize my chances of success. In this regard, a DSLR is the key, because it reduces the amount of gear required and also simplifies the capture process. I can fit my unguided Kenko Skymemo mount, Canon T2i body, two lenses, extra batteries, and green-laser pointer into one knapsack, and I am not just ready, I am airline ready! I started DSLR imaging more than seven years ago, but the technique continues to evolve and improve. Some topics that I will discuss in the future include the use of crop movie mode to take planetary images, and the introduction of the Leica M Monochrome (not the world's first consumer monochrome DSLR).
