Recent image taken with an Apogee Alta E42 2048x2048 CCD camera through the 0.4-m telescope.

The telescope is a 0.4-m f/8 RC, scale = 64.5 arcsec/mm.

The camera is an Apogee Alta E42 2048x2048 CCD.  The CCD chip has 13.5 micron x 13.5 micron pixels and imaging area of 27.6 mm x 27.6 mm.  With this imaging area and the scale of the telescope, the angular field of view is 29.7 arcmin x 297.7 arcmin.  The telescope scale on the chip is 0.870 arcsec/pixel.  There is no telecompressor.

Filter set = Bessell UBVRI and a clear filter.

A 25 second exposures at V on a 9th magnitude star will saturate the image.
