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.

Please note: The maximum sub length we will undertake with this pier is 900 seconds

Camera

FLI PL-16803 Mono CCD coupled to a FLI 10 position wheel and Astrodon 50mm unmounted LRGB & narrowband HA O3 S2 N2 3nm filters

All large glass Kodak sensors (apart from class 0) will have hot pixels and column defects which are completly normal, when you combine dithering, the supplied calibration frames and good user software calibration practices they are a none issue in the final image.

  • 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.
