First come, first served, until quantities last. We are no longer placing orders with manufacturers. Absolutely no rain checks. We reserve the right to cancel and refund orders at our sole discretion. We do our best to maintain our inventory accurate, but mistakes do happen, if you purchase an item that is no longer in stock, you will be refunded. The sale does not apply to some higher-end items such as 10Micron. Prices subject to change without notice. ALL SALES ARE FINAL.
Occasionally, we find a box under a box under a box in the back of the warehouse with hidden treasures, and when we do, we add these items on the site, so even though you may not find what you're looking for today, it could automagically appear next week.

Light Frames' are images (or a video) of a celestial object captured by the CCD. Each pixel in the images will have a numeric value that includes the influences of:
Light from the celestial objects in the field of view.
The various types of noise generated by the CCD.
Defects in the optical system.
CCD inhomogeneities (pixels more or less sensitive to light)
Optical vignetting (image is darker away from the centre)
Dust on the CCD window (seen as 'donut' shaped spots on the image)
Internal reflections
With calibration we will try to remove as much as possible of the Bias and Dark Current from each Light Frame.
Also, we will try to remove the effects of certain types of optical defect.
It has a rheostat for adjusting the light intensity.
Powered by 12 V; Cigarette lighter cable included.
With its three plastic screws you can fix to telescopes with diameters from 156 to 210 mm -
