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 so 300s is our longest exposure
if you book subs longer than this Roboscopes will contact you to alter them to more suitable lengths that suits the system!
The ZWO ASI-2400MC Pro Colour CMOS is one of Sony's new generation zero ampglow sensors. They are super sensitive with very low noise. Making them a paradym shift from the CCD cameras we are all used to using and require mjuch shorter exposures
This camera is set to Gain 150 as our default.
OSC & Narrowband Imaging with Pier-11
Although fitted with colour camera, we have also fitted it with some modern type fiters designed for OSC cameras
Askar Colourmagic HA/OIII 6nm - The filter enables the capture of the two main emission nebulae bands at the same time, whilst suppressing unwanted light pollution. It enables you to capture cleaner data and reduces the post processing efforts to isolate faint details from the background light pollution.
Askar Colourmagic SII/OIII 6nm - The filter enables the capture of the two main emission nebulae bands at the same time, whilst suppressing unwanted light pollution. It enables you to capture cleaner data and reduces the post processing efforts to isolate faint details from the background light pollution.
In essance this allows you to do Hubble Pallete narrowband plus colour images all from a OSC camera - What's not to like with that :)

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.

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