Recent DSO Images

The marriage of the Meade DSI, the C8 SCT and the Advanced VX mount is finally starting to pay off. All of my DSO imaging is done unguided. I do perform a two star align followed by four star calibration with an all star polar alignment (ASPA) on a star near the meridian. This is usually enough to give me nice round stars for less than 30 sec exposures unguided.

All images were acquired using Meade Envisage software in FITS file format. NASA / Fits Liberator 3 freeware was used to extract and enhance  R, G and B TIFF files. Paintshop Pro was used to colorize the TIFF files, apply touches to remove blemishes and to recombine them by merging layers.
