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 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!

CCD Camera

Moravian G4 16200 CCD camera with 16803 CCD chip 7 position filter wheel and OAG, combined with Astrodon 50mm unmounted LRGB & HA OII 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.

  • 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.

Calibration Files

This pier has a FREE calibration library, this includes a dark library that correlates to the most common subs lengths used, see below

  • 30s Darks
  • 45s Darks
  • 60s Darks
  • 120s Darks
  • 180s Darks
  • 240s Darks
  • 300s Darks

  • 600s Darks

  • 900s Darks

  • 1200s Darks

  • 1800s Darks

  • Bias Frames

  • Flat Frames - L, R, G, B, Ha, o3, S2

If you choose more individual sub lengths eg 550s, then darks are not included in the price and are taken for you on an individual basis. Please add darks to your imaging run in checkout.
