I bought the Orion 72ED on the 2008 black Friday at Orion, at a bargain price. Overall I would recommend this scope for its portability and overall quality/price ratio.
These pictures were taken without auto guiding, relying on the Mount polar alignment. I used a Celestron focus reducer for the M31 shot. Images have to be cropped – to hide coma on the edge.
DSLR: Non modified Canon XTi Rebel. Images processed with Max DSLR and Paintshop pro.
M33 – 5 exposures of 2 minutes each – 11/29/2008 – San Bruno – Orion 72ED
Pleiades – 11/30/2008 – 7 exposures of 2 min
M42 – 12 exposures of 2 min – 11/30/2008
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.
