William Optics FLT132 F/5.6 APO Refractor

Telescope

A William Optics FLT132 I hear you mutter, well before you go any further try it I dare you, it will shock you with how good it is I tell you. I have owned many 5” APO’s and this is as good if not better than all of them.

Its field is flat, it has tiny stars and colour correction is spot on, combine this with a relatively fast F5.6 and you have a short/medium focal length astrograph that ticks all the boxes.

When combined with the QSI660WSG CCD you get in a little closer in on your subject as well as maintain really good resolution due to the smaller pixel size.

Pier-7 is no slouch at F/5.6

So when combined with our skies 900 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 1200s subs!

CCD Camera

QSI660-WSG Mono CCD has Sony ICX694 6.1m sensor with 4.54um pixels, very hi QE and will sit at -20 all year round so noise is simply not an issue. Couple this to an 8 position wheel with Astrodon LRGB, 3nm HA OII SII NII filters and You have a killer combination.

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

N2 3nm	300-600s	900-1200s

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.
