How does the ESATTO 2" LP solve backfocus issues on a Celestron EdgeHD 8"?
The Celestron EdgeHD 8", especially with its 0.7x reducer, has only 105mm of backfocus. The ESATTO 2" LP's ultra-thin 32mm body consumes minimal space in the optical train, leaving enough room for your camera and other accessories. Its physical design also avoids collision with the telescope's mirror lock and manual focus knobs.
Can the ESATTO 2" LP handle a heavy imaging train with a large camera and filter wheel?
Yes. The focuser is rated for a payload capacity of 5 kg (11 lbs). This is more than sufficient to support a typical deep-sky imaging setup, including a cooled astronomy camera, a multi-position filter wheel, and an off-axis guider, without introducing flexure or focus shift.
What software do I need to control the ESATTO 2" LP from my computer?
You can control the ESATTO 2" LP from any Windows computer using the included ASCOM driver, which makes it compatible with most third-party astrophotography software. Alternatively, you can use PrimaLuceLab's own PLAY software, which provides an integrated control environment for ESATTO focusers and ARCO rotators.
How do I control the ESATTO 2" LP wirelessly for visual use?
The ESATTO 2" LP has built-in WiFi. You can connect to its network with any smartphone or tablet and use the free ESATTO Virtual HandPad app to control focusing wirelessly. This is ideal for making fine adjustments at the eyepiece without touching the telescope.
What is the benefit of the ARCO port on the ESATTO 2" LP?
The dedicated ARCO port allows you to connect a PrimaLuceLab ARCO rotator directly to the focuser. This single connection provides both power and data to the rotator, eliminating the need for a separate 12V power cable and USB cable. This simplifies cable management and reduces the risk of snags during an imaging session.
Is the 10mm travel of the ESATTO 2" LP enough for focusing with different filters?
Yes, for its intended use. The 10mm travel is designed for fine-tuning focus, not for large coarse adjustments. After achieving a rough focus with your telescope's manual focuser, the 10mm range is more than enough to compensate for the small focus shifts caused by changing filters (parfocal adjustments) or temperature changes during the night.
