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.

The only caveat to this setup is its best used when there is little to no moon or at the very least the moon a good way away being a one shot colour camera. So pick your target carefully when the moon is around!

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 60s is ample and 120s for a really dim subject, you just needs a lot more of them of course.

Most CMOS sensors suffer with amp glow on longer subs so this is another good reason to keep the sub lengths short.

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.

  • 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

  • 10s Darks

  • 30s Darks

  • 60s Darks

  • 120s Darks

  • 150s Darks

  • Bias Frames

  • 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.
