Telescope

ASA’s 12n F3.6 Wynne corrected Imaging Newtonian, these have a well deserved reputation As they combine speed with pretty good correction with large imaging sensors so what’s not to like

The great thing about these large aperture corrected newtonians when combined with big sensors, is you get a similar field of view to small 70-100mm APO's but with a massive jump in resolution and detail. You could not hope to achieve this with small aperture telescopes and once tried a big fast newt you will come back for more!

Pier-3 is a very fast F/3.8

So when combined with our skies 900 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 1200s subs!

CCD Camera

A FLI PL16803 CCD camera which in all honesty is still the daddy when it comes to imaging. Superb cooling, fast downloads and very clean images combined with 9um pixels and 52mm diagonal sensor it really is hard to beat.

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
