Connect a standard RJ-12 cable from
the G4’s autoguider relay port to the
ST-4 compatible autoguider port on
your equatorial mount
(Figures 23.1
and 23.2). Connect the G4 to the USB
on your computer as you normally
would, and operate the camera with an
ASCOM compatible program like PHD
Guiding.
7. Optional
Accessories
For the StarShoot G4 Monochrome
We recommend Orion 1.25" LRGB
and narrowband imaging filters and a
filter wheel to capture high quality color
images.
For the StarShoot G4 Color
An optional IR-blocking filter can be
threaded to the G4 camera body to
block the IR. This can help sharpen
your images, and is especially helpful
when used with some refractors which may allow more unfocused IR light to
create color halos around bright stars.
Both cameras can benefit from a USB extension cable, available from Orion.
We recommend a portable field battery to power the TEC.
