Well after some looking at reviews it looks attractive.
I read the user manual :
http://www.astrotrac.com/media/Astro...%20-%20Web.pdf
My SP mount weighs 4kg and this mount only 1kg (plus about 0.5kg of the Manfrotto tripod head I already have, which saves 2.5 kg in my air travel luggage. But how should I mount the Televue Genesis on the Astrotrac ??
And isn't the $220 polar scope a Requirement ?
I see some sketches of the sky in the user manual with the surroundings of both poles (resp Crux+Achernar and Ursa Major+Cassiopeia). Is there a reticle supplied ?
The 20 years old SP mount with polar finder is very accurate: point the +7 star BQ Oct (not Sigma Oct !) in the center of the polar scope and voilą ready to track at least 5 minutes per frame with the Genesis.
So only the 2.5kg luggage gain is a reason to buy it.
