Astrophotography by Peter Bresseler
Most of my astrophotography time is spent on deepsky imaging using lucky imaging techniques, this means short exposures in the range of 500 ms to 5 seconds per sub. With short exposures you do not need an expensive mount, auto-guiding is also not needed and the frames you take are often sharper. I can not take images more than 1.5 - 2 hours per session, because at home I have a limited field of view due to large trees and houses of neighbors...it is my little challenge.
Chi Persei (NGC 884) + H Persei (NGC 869), 1800 x 1 s., ASI183MC pro, RASA C11 f/2.2
The Celestron 11" f/2,2 RASA Rowe-Ackermann Schmidt Astrograph is a dedicated instrument, it can only be used at f/2.2 like a Schmidt-Camera. The RASA C11 is not a lightweight, it has a tube weight of 43 lbs (19.5 kg).
Lucky Imaging is an effective technique for delivering near-diffraction-limited imaging on telescopes.
The most successful type of data collection by the amateur is the transit method. As a planet passes over the portion of the star facing us, the light curve of the star drops for a time. As the planet passes through, the light curve returns to normal.
You can further improve resolution of your images by improving your FWHM.
