Telescope

This is a "656 telescopes" by peter Shah corrected Dall Kirkham with a nice flat field and a moderate speed for the aperture at F6.8, at 2017mm its a great focal length but in this case we have combined it with a KAF-16803 which allows high resolution imaging combined with a substantial FOV. This brings a whole host of larger subjects into play at a much larger aperture without breaking your imaging budget.

Pier-2 is pretty nimble at F/6.8, so when combined with our skies 1200 seconds is the longest sub we do

Camera

A Moravian G4 16803 Large format sensor with a very useful 9µm pixel size that you can bin 2x2 on longer focal lengths like this while still keeping plenty of pixels in reserve

All large glass Kodak sensors (apart from class 0) will have hot pixels and column defects which are completly normal, when you combine dithering, the supplied calibration frames and good user software calibration practices they are a none issue in the final image.

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.
