Telescope

Very few people have a long enough focal length telescope and Skies to image up close and personal but this one at 2720mm when combined with an APSC CMOS sensor manages to juggle FOV while still keeping a decent image scale of smaller objects like planetary nebula, globs and other interesting objects.

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 30/60s  and 120s is more than ample enough for narrowband, you just needs a lot more of them of course.

The ZWO ASI-2600MC Pro Colour CMOS is one of Sony's new generation zero amp glow sensors, so no need to worry on that count :)

This camera is set to fixed Gain 100 as our default, if you have any special gain and offset requirements for CMOS imaging please discuss and we will do our best to accommodate you.

Please note: The maximum sub length we will do on this pier is 300s

  • 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.

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

  • 5s Darks

  • 10s Darks

  • 20s Darks

  • 30s Darks

  • 45s Darks

  • 60s Darks

  • 90s Darks
