Please note that the secondary telescope that is used for auto-guiding would further increase your choices for locating
a suitable guide star if it is held in collimating rings, like a huge finder scope. This would allow you to easily locate a
suitable guide-star even under very difficult conditions.
Imaging and Auto-Guiding with a Single Telescope
An alternative setup will involve a single telescope for imaging and auto-guiding purposes instead of two different
telescopes. As such you will require the following items to be able to image and auto-guide.
1. An imaging camera, i.e. Opticstar DS-616C XL+.
2. An imaging telescope, i.e. Opticstar/Ascension 102ED Triplet APO.
3. An off-axis guider
4. An auto-guide (ST-4) compatible mount, i.e. EQ5 PRO, EQ6 PRO, etc.
5. PC with USB2.0 or USB 3.0 ports running Windows XP/Vista/7/8/10.
6. The Opticstar PX-126 camera and software to be used as a guide camera.
7.
ASCOM software platform
.
8. Auto-guiding software, i.e. PHD Guiding 2.
The following diagram demonstrates how the components listed above are assembled together into a complete
imaging and auto-guiding setup using a single telescope.
