What kind of filters can I use with the Player One Phoenix 7x2" Filter Wheel?
The Player One Phoenix Filter Wheel is designed to accept 2-inch mounted filters (frame ≤ 8.5mm, thread ≤ 2.5mm) or 50mm unmounted filters. This includes broadband LRGB (Luminance, Red, Green, Blue) filters, narrowband filters (like H-alpha, OIII, SII), and multi-bandpass filters. The 7-position carousel provides enough space for a complete LRGB and narrowband set to be installed at the same time.
Is the Phoenix 7x2" Filter Wheel a good match for my full-frame monochrome camera like the ZWO ASI6200MM?
Yes, it works: the full-frame Player One Zeus series is among the supported cameras, and the 2-inch filter format avoids the heavy vignetting (darkening of the corners) that 1.25" filters would cause on a large sensor. For the least vignetting on a full-frame sensor, though, the Phoenix 7x50mm wheel, whose 49mm clear path is larger than the 7x2" wheel's, is the better choice. The seven slots allow you to build a comprehensive filter set for capturing both true-color and detailed emission data from objects like the Orion Nebula (M42) without ever needing to open the imaging train.
How do I control the Player One Phoenix Filter Wheel during an imaging session?
The Player One Phoenix Filter Wheel connects to your computer through its USB Type-C data port. Player One provides a filter wheel ASCOM driver and an INDIGO filter wheel driver for the Phoenix series, so ASCOM imaging software such as N.I.N.A. or Sequence Generator Pro can automatically rotate the wheel to the correct filter as defined in your imaging sequence.
What is the advantage of a 7-position wheel over a 5-position wheel?
A 7-position wheel allows you to keep a full set of LRGB filters (4 slots) and a full narrowband SHO palette (3 slots for SII, H-alpha, and OIII) installed simultaneously. With a 5-position wheel, you would have to choose, for example, between LRGB filters or a narrowband set, requiring you to physically swap filters if you wanted to image different types of targets in the same night.
Will the Phoenix 7x2" Filter Wheel work with my f/4 Newtonian telescope?
Yes, the Player One Phoenix is compatible with fast optical systems like an f/4 Newtonian. The key consideration with fast scopes is achieving correct back focus and avoiding vignetting, which the 2-inch filter format is designed to do. Ensure you have the proper adapters and spacing to meet your camera's back focus requirements for sharp stars across the field.
How is the Player One Phoenix Filter Wheel powered?
Like most modern astronomy filter wheels, the Phoenix is typically powered directly through its USB connection to the control computer or hub. This simplifies cable management, as it does not require a separate 12V DC power supply.
