G2CCD Camera Head
 Integrated, compact and robust camera head containing all electronics, mechanical shutter and filter wheel was one of the important design targets of G2 CCD cameras. No other parts (like CPU box, USB converter etc.) are necessary (with the exception of external “brick” 12 V DC power supply).

Camera head measures just 114 × 114 × 74 mm (approx. 4.5 × 4.5 × 3 inches). The backfocus (distance from the camera front to the CCD chip) is 25 mm (1 inch).

Robust camera head

All parts (mechanical blade shutter, filter wheel with 5 positions for standard 1.25" filters, Peltier cooler with fans, camera and supply electronics) are inside the head.

Just two connectors (USB-B and power jack) are on the side of the camera body.

The camera is supplied with standard 1.25" barrel adapter by default, but the user can choose any other adapter he/she prefers. Another adapters can be ordered separately.

It is possible to choose among various telescope/lens adapters:

  • 1.25" barrel adapter

  • 2" barrel adapter

  • T-thread (M42 × 0.75) adapter

  • Zeiss (M44 × 1) adapter

  • Praktica lens (M42 × 1) adapter

Twin quiet, ball-bearings fans exchanges approx. 20 cubic meters of air per hour to provide sufficient cooling for the hot side of two-stage Peltier cooler.
