Telescope

The Epsilon 180 is a blisteringly fast F2.8 corrected newtonian astrograph that was designed for DSLR cameras, whilst it works very well that way we think the new generation CMOS cooled cameras are a far better combination. At 500mm FL this is the perfect telescope for big nebular and larger galaxies. This is a good scope if you want a lot of quality data fast and don’t want the complexity of mono imaging etc.

Pier-5 is a fast Unguided system

The telescope is F/2.8 and is fitted with a low noise CMOS camera set to unity gain, even the dimmest object can be imaged with subs of this length. if you book subs longer than this Roboscopes will contact you to alter them to more suitable lengths that suits the system!

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.

  • Although we have taken Bias frames we do not recommend using them with CMOS sensors.

  • 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

  • 5s Darks

  • 10s Darks

  • 20s Darks

  • 30s Darks

  • 45s Darks

  • 60s Darks

  • 90s Darks

  • 120s Darks

  • 180s Darks

  • 240s Darks
  • 300s Darks

  • Flat Frames

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.

CMOS Cameras do not need Bias frames as part of their calibration routine.
