Learn what the Quark to C & T adapter bundle includes and follow a step-by-step setup to attach a C- or T-thread camera to your Daystar Quark for solar imaging.
Quick answer
Use the Quark to C & T adapter bundle when you want to attach a C-mount or T-mount camera directly to your Daystar Quark for solar imaging. The bundle gives you both adapters, so you can switch between camera threads without buying them separately.
Why direct camera mounting matters for solar imaging
The Quark is an eyepiece-style hydrogen-alpha filter, so the camera sits behind it. A direct, rigid connection reduces flex and keeps the camera square to the optical axis, which helps maintain even illumination and sharp detail across the solar disk.
The bundle includes knife-edge baffles for contrast, and it is compatible with the Interference Eliminator, which is recommended for removing banding from Newton's rings. If you plan to image the Sun, those details matter more than the adapter's price.
When the bundle is the right choice—and when it isn't
Choose the bundle if you own both C-mount and T-mount cameras, or if you expect to move between them. Buying both adapters together saves you from ordering a second adapter later.
If you only use one camera thread, a single adapter may be enough. Also check that your camera's flange focal distance and back-focus requirements match what the Quark expects; the catalog does not list a back-focus specification, so verify with your camera and Quark documentation before relying on the adapter alone.
Step-by-step: attaching your camera with the Quark adapter bundle
- Identify your camera thread: Check whether your camera uses a C-mount (1-inch thread) or T-mount (M42 thread). Pick the matching adapter from the bundle. Common mistake: assuming all cameras use T-mount; C-mount cameras need the C adapter. If unsure, measure the thread diameter or check the camera manual before attaching anything.
- Attach the adapter to the Quark: Thread the chosen adapter onto the Quark's male thread. Hand-tighten only. Common mistake: over-tightening, which can damage threads or make removal difficult. Stop as soon as the adapter seats firmly; do not force it.
- Mount the camera: Thread your camera onto the adapter. Support the camera while threading to avoid cross-threading. Common mistake: letting the camera hang unsupported, which can stress the threads. Check that the camera sits flush and does not wobble.
- Add the Interference Eliminator if needed: If you see banding from Newton's rings, install the Interference Eliminator (sold separately) as recommended. Common mistake: ignoring banding and assuming it is a camera fault. Test on a uniform light source before solar observing to confirm the fix.
- Balance and focus: Recheck balance on your mount after adding the camera and adapter. Focus carefully; the added weight may require a slight mount adjustment. Common mistake: skipping balance check, leading to tracking errors. Do a dry run in daylight to confirm the setup is secure before solar observing.
