Pier 1

656 Imaging AD250 10" Corrected Dall-Kirkham

Telescope

At 1700mm this telescope is a brilliant step into medium focal length imaging when combined with a smaller sensor. It’s perfect for getting up close and personal with many of the smaller nebulas and galaxies as well as taking higher resolution shots of interesting sections within much larger ones. It’s a corrected Dall Kirkham with a nice flat field.

Pier-1 is pretty nimble at F/6.8

So when combined with our skies 1200 seconds is generaly as long a sub you will ever have to do even for narrowband. so unless the object is super super dim there is no need for 1800s subs!

CCD Camera

The FLI ML-8300 is by far the best varient if the 8300 sensor as it has the best cooling and lowest read noise in its class, not to mention superb download times

For your convenience and ease of use we have taken the time to calculate this setup for filter weightings which if followed will help you to maximise your imaging time. For more information on this visit our FAQ's page

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.
