SBIG® STC-428-P Photometry Package

Problem: We need a compact, high performance imaging system for photometric observations.
Solution: STC-428-P provides extremely high sensitivity, low noise 7 megapixel imaging with support for commonly-available UBVRI filter sets.

The STC-428-P is the ideal package for photometry, featuring:

  • High sensitivity, low noise 7 megapixel IMX428 imaging sensor
  • Low noise and huge dynamic range capability via StackPro™
  • Two-stage thermoelectric cooling for minimal noise on long exposures
  • SmartCooling™ active temperature regulation to 0.1 degrees C for high calibration stability
  • Eight position FW8-STC filter wheel, with one slot configured as a dark frame shutter
  • High-speed USB 3.0 interface (USB 2.0 compatible)
  • MaxIm LT control software

The new STC-428-P scientific CMOS camera represents a major improvement over CCD technology. Compared with previous CCD models such as the STF-8300M, the STC-428-P features higher sensitivity (78% QE versus 56%), significantly lower read noise (2.5 e- versus 9.3 e-), and 20X faster readout.

While a single exposure on the IMX428 sensor can equal CCD dynamic range, the combination of fast readout and very low read noise allows for stacking many shorter to produce greater dynamic range than previously possible. The built-in StackPro™ capability can automatically divide your exposure into up to 16 shorter sub-exposures, and stack them inside the camera prior to download. This dramatically increases dynamic range without imposing greater processing requirements on the host computer – with read noise equal to or lower than comparable CCD cameras.

Our SmartCooling™ active regulation maintains the sensor temperature to within 0.1ºC, and minimizes fan speed based on heat sink temperature for longer life and quieter operation.

Sensor Specifications:

  • SONY IMX428 CMOS imaging sensor
  • 3208 x 2200 pixels / 7.1 megapixel
  • 4.5 micron pixels
  • 17.6 mm diagonal
  • Peak QE 78%
  • 12-bit A/D conversion with low-gain and high-gain modes
  • Very low read noise ~ 2.5e-
  • Very low dark current < 0.1 e-/pixel/sec @ 0C
  • 80 dB dynamic range

The STC-428-P supports several optional gain modes:

  • Low Gain (Gain 5.5 e-/ADU; Full Well ~ 55,000 e-; Read Noise ~5 e-)
  • Medium Gain (Gain 2.45 e-/ADU; Full Well ~ 10,000 e-; Read Noise ~ 2.3 e-)
  • High Gain (Gain 1.2 e-/ADU; Full Well ~ 5,000 e-; Read Noise ~ 1.9 e-)

StackPro™
The STC-428-P scientific CMOS camera features StackPro™, a revolutionary feature that performs image stacking inside the camera. While the IMX428 sensor has dynamic range on a par with its CCD predecessor, it is limited to 12 bit data (0-4095). At the same time it also has far lower read noise, which means you can stack many more shorter exposures without degrading signal-to-noise ratio. As great as this sounds it does result in a lot of extra disk usage and post-processing.
StackPro™ performs the stacking automatically, inside the camera. It automatically subdivides your exposure into up to 16 individual sub-exposures, and stacks them inside the camera prior to download. This eliminates the excessive amounts of data cluttering up your hard drive.

Eight Position Filter Wheel
The STC-428-P page includes an FW8-STC. This wheel supports standard unmounted 36 mm filters. To enable the use of less-expensive and commonly-available 1-1/4″ mounted UBVRI filters, a set of five 10105 36 mm to 1-1/4″ Mounted Filter Adapters is included with the package.
Also included is an opaque “filter”, which acts as a dark frame shutter for efficient image calibration. The camera will automatically select filter slot 8 when a dark frame is requested. This eliminates the extra cost and complexity of a separate mechanical shutter. If an eighth filter is needed then the dark frame feature can be disabled.

Included Software
The STC-428-P comes with MaxIm LT software, which provides complete camera control and image calibration functions. MaxIm LT can also be upgraded to MaxIm DL Pro for full photometric analysis capability.
