Some pictures taken for San Bruno, CA – highly polluted site close from the SFO airport.
Telescope: Orion 102ED, with Canon XTi Digital Rebel, and Orion auto guider.
I used a Bahtinov Mask to focus the DSLR, and an Orion Skyglow anti-pollution filter. Pictures were processed with MaxDSLR and Painshop Pro.
