Planetary nebulae

Notizen: NGC 6804 This night transparency was BAD (in bold letters) but the seeing good, so I did a "small but bright planetary nebulae with short exposure times without focal reducer night". At f/6.3 the camera gives a scale of 1.35 arcseconds/pixel which by my standards is high resolution. I should have done longer individual exposures but it took me a while to realise that the scope could track quite well at that scale, so I first went with short exposures to avoid trailing. Taken from the middle of Berlin with an 8" LX200 at f/6.3, MX716 camera, video autoguider, UHC filter for 30x60 seconds.
