Cluster by Michael Breite

Leo I "Harrington-Wilson 1" Dwarf Elliptical Glx.

Exposure Data: 19.02.2004. L=12x5min. (1x1 - 3"/Pixel), compl. 1 hour.
Processing: Acquired via MaxIm DL, no darks+flats, Sigma combined, RL-deconvolved in AIP4Win, processed in Photoshop and Neat Image.
Optical System: 112/440mm Astrograph, Starlight Xpress SXV-H9, Vixen GP-DX ESCAP-FS-2-GoTo. Astronomik Filter wheel FR-03, Type IIc-Filters. Guiding scope Fluorite 55/440mm guided with Starlight Xpress SXV-Autoguider camera.
Comments: First light for my new portable Instrument. It is a Newtonian telescope with 46%-Obstruction, MPCC-Coma-Corrector, enough backfocus for the Filter wheel and CCD-camera. The raw-stars are around 4 arc-seconds FWHM. The pixel size is 6,45 micrometer - that means, the Astrograph produces stars around 8 micrometer (like a Takahashi Epsilon - for 1/6 the price).
A night with average transparency! Picture downsampled 30% for a better view.
The bright Star is 1 mag. Regulus.
