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
The ZWO ASI-2600MM Pro Mono 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 much shorter exposures
This camera is set to Gain 100 as our default.

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.
