Telescope

At 1678mm this telescope is a brilliant step into medium/long focal length imaging when combined with a smaller 4/3rds sensor. It’s perfect for getting up close and  personal with many of the smaller nebulas and galaxies as well as taking higher resolution shots of interesting sections within much larger ones. It’s a corrected Dall Kirkham with a nice flat field.

If you are a member of one of our Wide-field Syndicates like Pier 13/14 then this scope would complete your needs for multi season imaging as it will take you through galaxy season as well as allow you a whole year of Globs, Planetary Nebs, Boks & Abell's to mention a few things :) :)

Pier-1 is pretty nimble speed wise at F/6.8

CMOS Camera

Just in case you have never used CMOS and have been using CCD like the rest of us for the last million years then let me tell you it requires a different approach, you can forget long subs as the are not needed and at most times detrimental to your image quality. Allowing for CMOS’s sensitivity, higher dynamic range and super low read noise broadband imaging typically 60s is ample and 120s for narrowband, you just needs a lot more of them of course. This camera is set to Unity Gain as our default.

Please note: The maximum sub length we will do on this pier is 600s. Although in our opinion this pier needs no more than 300s for narrowband and simply more subs as CMOS due to its super low noise and sensitivity benefits far more from more shorter subs than the long ones CCD cameras required.

  • 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.
