Merry Christmas and happy new year 2011
Photographed at night of 11. and 12. december.




Jalusta guidaamattomana ilman järkkäriä kyydissä. QHY5 valotusaika 1,5s. Nauhoitusta noin 1000s ja kyllä tuosta on jonkinlaista jaksollisuutta havaittavissa.
2min, ISO1600, 30D, Unguided.
Sama setup, eri tähti, guiderin valotusaika 2s-2,5s. Logista otettu pala 1000s-2000s kohdalta koska jossain 500s paikkeilla oli iso piikki, johtuisiko jalustan tönäisystä?
2min, ISO800, 30D, Guided w/ QHY5+PHDGuiding.
I Opened this (2010-2011) season by photographing the M57 Ring Nebula in 8/9/2010. At night was an excellent opportunity to test CG-4 autoguider port´s operating. Weather was little bit foggy but it didn´t matter for testing. Picture is cropped down about 50%, because dimension of M57 is only about 1,4x1,0 arc min.












Here it is. My low budget amateur roll off roof observation shelter. I build it using recycled materials in last summer. There is a fixed pillar in the middle of floor and top of it Celestron CG-4 mount. Telescope is Celestron Omni XLT 150 newton and I use it both visual and photographic purposes. I think Celestron Omni 150 is good choice for beginners like me. It isn´t too expensive but quite good quality.
