Description

This is a mosaic from one camera and two telescopes on three occations.

Background is done with a 700mm F6.5 apo but for the galaxies I used my Meade LX200-ACF plus 0.78x reducer. Each one of those got 26x15 min @iso200 with a modded Nikon D7000 and CLS filter.

Mount is HEQ5 Pro, guided with a standalone NexGuider. Captured with DslrDashboard on Android tablet.

No darks, flats or bias used.

Processing with Registar, PS and Topaz Suite.
