And for a beginner I would recommend a GoTo and some additional software to do plate solving - learning to star hop, with such a restricted field of view and by the look of it, non-optimal skies- is a very quick way to put off a beginner as they 'can never find anything' (Cue debate on GoTo) Neil

I've got the Pegasus Focuscube - which is a newer version just has all the electronics in one place (one on my C11 and another on my 127mm APO), - take a look here: http://astro58.wixsite.com/havenobservatory/focuscube Regards Neil
