Description

Cluster of galaxies in Virgo taken with my RASA 8( 2 nights)
Combination of 2 Nights : one with ASI294MC camera for color and one night for Luminance with ASI1600MM camera. Quite difficult to get propoer colors due to polluted skies, so it has been necessary to redo the color shots again...that's also one of first attempt to combine RVB and L from 2 different cameras (I have got some issues with camera rotation angle)
- ASI294MC - RVB : 85 X 80 seconds
- ASI1600MM - L : 58 x 120 seconds
Hope it's good enough!
