William Optics 90mm Megrez APO F7.1 (f:640 mm) test with Tele Vue Paracorr Coma corrector, SBIG ST-4000XCM -25C 0h30min (3x600sec).
This was a test to see how the newtonian coma corrector would be able to flatten the field of the WO90, it's resonable but of course not perfect.
Light travel time: 2.54 mill years.
Processing: CCDSoft, Astroart 5.0.
