What is the primary purpose of the Daystar Quark to C adapter?
The Daystar Quark to C adapter is designed to create a direct, secure threaded connection between a Daystar Quark solar filter and a camera that uses C-mount threads. This provides a rigid imaging train, which is critical for high-resolution solar photography.
How does the Daystar Quark to C adapter improve image quality?
Beyond providing a rigid, tilt-free connection, the adapter features internal knife-edge baffles. These baffles are designed to trap stray light and prevent internal reflections, which significantly improves image contrast by darkening the background sky.
Will this adapter solve Newton's rings in my solar images?
No, not by itself. This adapter is designed to be compatible with Daystar's C-thread Interference Eliminator (sold separately), which is the component that actually corrects for Newton's rings. The adapter provides the correct threading and spacing to place the Interference Eliminator in your imaging train.
What is the optical path length added by the Daystar Quark to C adapter?
The adapter adds 10mm of optical path length from flange to flange. The total physical length of the adapter is 19mm.
I'm using a ZWO ASI174MM with my Quark for H-alpha imaging. Is this the right adapter?
Yes. The ZWO ASI174MM is a popular solar imaging camera that uses C-mount threads when its 1.25" nosepiece is removed. This adapter will allow you to thread the ASI174MM camera body directly to your Quark for a very secure connection.
If I see banding patterns when imaging the Sun's chromosphere with my Quark, will this adapter help?
The banding patterns, often called Newton's rings, are a common issue in H-alpha imaging. This adapter is the first step to solving them, as it allows you to integrate the C-thread Interference Eliminator into your setup. The combination of this adapter and the Interference Eliminator is the recommended solution.
