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/3.6 when used with a CMOS sensor the longest exposure needed is 300seconds

 

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 120-1300s is more than ample enough for narrowband, you just needs a lot more of them of course.

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

This camera is set to Unity Gain 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.

  • 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
