We are pleased to be able to announce the availability of a new medium resolution optical survey created by Axel Mellinger. This three color all-sky survey provides beautiful large-scale true-color images of the sky. For regions less than 30 degrees, the resolution is about 0.01 degrees. For larger regions the data is sampled from 0.1 degree pixels. For more information on these data check out the survey web site.
This survey provides an excellent complement to medium and low resolution surveys in other wavelengths, e.g., IRAS/IRIS and RASS and the new Fermi gamma-ray surveys that we plan on introducing in the next few weeks.
Many thanks to Dr. Mellinger for allowing us to include these data in SkyView.
The image above was created using the following arguments.

The Mellinger survey is only available through the SkyView web site and cannot be retrieved using a local copy of the Jar file. The survey sets some defaults differently from other surveys. The default scaling is linear and the min and max values are set to 0 and 255 to preserve a consistent scaling regardless of the region you happen to pick out. We also set the ClipIntensive keyword when the Clipping sampler to preserve the scaling.
