RCOS are synonymous with quality and after installing this one I can see why, no corners have been cut at all in the build of this Ritchey Chrétien 12.5” telescope. It’s built like a tank has all the nice touches from front focusing, auto fans to dew control and proper honeycomb flocking, on top of this it has 1/20th PV Zerodour mirrors.
Pier-12 is not fast and typical RC speed at F/9, however when combined with our skies 1200 seconds is generaly as long a sub you will ever have to do even for narrowband. so unless the object is super super dim there is no need for 1800s subs!

Imaging subjects with brighter cores will of course require shorter sub lengths for HDR, your personal experience will be needed to gauge this yourself.
Please remember this is only a guide above, we are just trying to help you have the best experience possible remote imaging with Roboscopes.
Roboscopes supply the site and control the equipment but you choose everything else from filters, object/co-ordinates to sub lengths. So you need to exercise due diligence and experience when booking because if you fill the booking form out with incorrect details then you will get precisely that.
It is not Roboscopes responsibility to check your detailed requirements after you have booked.
