This image comes from test exposures to dial in stray light removal in the 10inch F4 Newtonian scope. A sparsely populated area in Bootes was chosen but in the end a nice little galaxy cluster in a shape resembling Markarian's Chain in Virgo was on the images and it is worth to process the test exposures into a final image. Exposure and processing: Dither guiding, dark & flat calibration, gradient removal, sharpening, noise removal.
