Telescope

Planewave CDK 17” f/6.8  Dall Kirkham, a good quality instrument with a large flat field and pretty fast optics, a large aperture high resolution light bucket.

Pier-8 is pretty nimble at F/6.8, so when combined with our skies and FLI's latest generation CMOS dual read camera 300 seconds is generaly as long a sub you will ever have to do even for narrowband. Broadband imaging requires much shorter exposure unless it's a very dim object. If in doubt please ask :)

CCD Camera

Finger Lakes Instruments Kepler 4040 Cmos camera with a similar size sensor to the venerable 16803 Sensor but much lower read noise, sensitivety plus dual High & low dynamic read

7 position filter wheel and OAG, combined with Astrodon 50mm Sqre unmounted LRGB & HA 5nm OII 3nm SII 5nm narrowband filters

For your convenience and ease of use we have taken the time to calculate this setup for filter weightings which if followed will help you to maximise your imaging time. For more information on this visit our FAQ's page.

Please note: The maximum sub length we will undertake with this pier is 300 seconds

  • 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.
