What kind of performance can I expect from the IDEAL 12's standard 1/6 PV optics?
The standard 1/6 PV wavefront optics provide demonstrably sharper and higher-contrast images than typical "diffraction-limited" telescopes. You can expect pinpoint stars across a well-corrected field (with an appropriate coma corrector) and the ability to resolve fine detail on planets. Each IDEAL 12 comes with a Zygo test report, guaranteeing this level of optical quality.
What class of mount is required for the IDEAL 12 OTA at 14kg?
With a tube weight of 14kg, the IDEAL 12 OTA is best paired with an equatorial mount in the EQ6/CGEM class or greater for visual use. For serious astrophotography, a mount with a higher payload capacity (e.g., 50 lbs / 22 kg or more) is recommended to handle the additional weight of a camera, guide scope, and other accessories.
Can the Eris 2" Rack and Pinion focuser on the IDEAL 12 handle a heavy imaging camera and filter wheel?
Yes. The Eris 2" Rack and Pinion (R+P) focuser is specifically designed for stability. Unlike Crayford-style focusers that can slip under heavy loads, the R+P mechanism provides a positive, non-slip action capable of supporting a full imaging train without flexure or tilt.
How will the IDEAL 12 at f/4 perform on Jupiter with a Barlow lens?
The IDEAL 12's 300mm aperture provides immense resolving power for planets. To bring Jupiter to a suitable image scale, you would use a 3x or 5x Barlow lens, effectively changing the focal ratio to f/12 or f/20. The 1/6 PV optics (or higher) will ensure you can resolve fine details like the Great Red Spot, barges, and subtle cloud belts, provided atmospheric seeing is good.
Is the IDEAL 12 a good choice for imaging large targets like the Andromeda Galaxy (M31)?
Absolutely. The f/4 focal ratio and 1200mm focal length are an excellent combination for large deep-sky objects. Paired with a full-frame sensor and a coma corrector, the IDEAL 12 can frame the entirety of the Andromeda Galaxy (M31) or the North American Nebula (NGC 7000), capturing faint outer details thanks to its large 300mm light-gathering aperture.
When should I consider upgrading the IDEAL 12 to 1/8 PV or 1/10 PV optics?
You should consider the optical upgrades if your primary focus is high-resolution lunar and planetary imaging. While the standard 1/6 PV optic is excellent, a 1/8 PV or 1/10 PV mirror will deliver visibly higher contrast on low-contrast details. This makes a real difference when trying to capture subtle features within Jupiter's zones or faint craterlet chains on the Moon.
