un alt M13

-----------------------------------

Aseara desi vremea a fost mizerabila (transparenta scazuta si seeing prost - fwhm > 6, poluare luminoasa (de acasa)) si M13 cam jos, am testat putin echipamentul:
heq5, orion optics 200mm f/4.5, baader mpcc, autoghidaj;
canon 550d la iso 400, 20 x 3 min, 13 darks, 32 biases, dithering.
