Meeting @Sterrenjutters - Lecture by Dierick Dominique

Yesterday, April 8th, I went to Koksijde, "De Sterrenjutters"  for a lecture from Dierick Dominique about the use of DSLR in astophotography.  About 25 people attend this meeting, mainly members from De Sterrenjutters.
From presenters experience the use of reflexcamera's is a very good alternative for CCD camera's except if you are a scientist.

Good examples were shown using DSLR Nikon D810a. Any other DSLR would fit for use when modified by taken the filter out sits in from of the CCD/CMOS chip.

In his opinion best results within a reasonable budget are realised using a modern guiding system (Skywatcher EQ5/6 Celesteron, 10micron, ..) and a refractor telescoop. He was not in favour of reflector telescoops type newton, ritchy c, matsukov, ..

If choosing refractors a good choice would be APO triplet refractors 80/100/120/150 with flateners.
Software for editing picture are also discussed ... Maxim, Nebulosity (not for Nikon), photoshop.

At last calibration of pictures are discussed : bias, darks, flat frames and how to stack pictures in photoshop.
