Telescope
Planewave CDK 17” f/6.8 Dall Kirkham, a good quality instrument with a large flat field and pretty fast optics, a large aperture high resolution light bucket.
-
Camera
Fitted with FLI's latest and greatest generation Kepler 4040fi 52mm diagonal camera, This camera is exceptionally sensitive and requires very short exposures for all types of imaging
In most cases the maximum sub length we will do on this pier is 180s, if your object is exceptionally dim with no bright stars in the field you may request 300s exposures. However, in 99% of cases they are simply not needed with this particular sensor's characteristics!

Filters
This pier is fitted with every conceivable filter you would dream of owning, as it's fitted with FLI's largest 10 position 50mm x 50mm filter wheel
It even has Helium II, so imaging planetary nebula becomes a whole heap more interesting
- LRGB are Astrodon Gen2
- HA O3 S2 N2 are all Astrodon 3nm
- HB is 8nm
- He2 is 10nm
