Replacement Illuminator for Polar Finder EXOS2/EXOS2GT
This replacement LED illuminator is designed specifically for Explore Scientific’s EXOS2 and EXOS2GT mounts, providing variable deep red illumination for 50mm reticle finder scopes. It ensures your polar alignment reticle is clearly visible without compromising your dark adaptation and is powered by two standard AA batteries (not included).
Precision Polar Alignment: Variable Red Illumination for 50mm Finders
Proper polar alignment is critical for long-exposure astrophotography, and seeing the reticle clearly is the first step. This illuminator bathes your polar scope's reticle in deep red light, which preserves your night vision while making the alignment markings stand out. The variable brightness control lets you dial in the perfect intensity, ensuring the reticle is visible without washing out faint guide stars like Polaris.
EXOS2/EXOS2GT Compatibility: Powered by 2 AA Batteries
Engineered as a direct-fit replacement for the illuminator on Explore Scientific EXOS2 and EXOS2GT mounts, this unit integrates seamlessly with your existing 50mm polar finder scope. It runs on two AA batteries, a common and readily available power source, so you won't be caught with a dead illuminator during a critical imaging session. Note that batteries are not included.

Why is the light red on the EXOS2/EXOS2GT replacement illuminator?
The illuminator for the EXOS2/EXOS2GT uses deep red light to preserve your night vision. Red light has the least impact on the eye's dark adaptation, allowing you to see the faint stars needed for alignment while still clearly viewing the reticle markings.
How do I control the brightness on this EXOS2/EXOS2GT replacement illuminator?
This replacement illuminator features a variable brightness control, typically a small dial or knob. This allows you to adjust the intensity of the red LED to match your sky conditions, from dark, transparent nights to moderately light-polluted locations.
Is this replacement illuminator compatible with any other mounts besides the EXOS2/EXOS2GT?
This illuminator is specifically designed as a replacement part for the Explore Scientific EXOS2 and EXOS2GT mounts. Compatibility with other mounts or finder scopes is not guaranteed and it should be purchased for its intended purpose.
What kind of batteries does the EXOS2/EXOS2GT illuminator use?
The replacement illuminator for the EXOS2/EXOS2GT is powered by two standard AA batteries. These are not included with the product and must be purchased separately.
I'm trying to polar align my EXOS2GT mount in a light-polluted area. How does this illuminator help?
In light-polluted skies, Polaris may be visible but fainter guide stars can be washed out. The variable brightness control on the EXOS2/EXOS2GT illuminator is key here. You can turn the brightness down to the lowest visible level, which keeps the reticle sharp without creating glare that would overwhelm the faint stars you need to see for precise alignment.
I have an iEXOS-100 mount from Explore Scientific. Will this EXOS2/EXOS2GT replacement illuminator fit it?
No. This replacement illuminator is designed for the polar finders on the EXOS2 and EXOS2GT mounts only. The iEXOS-100 uses a different polar scope and illuminator system, and this part is not cross-compatible.
