Ha image of emission nebula IC410 acquired using my system at AstroCamp, Nerpio, Spain. Comparing this with the image of IC410 (below) taken using my ST-10/Megrez 120 system in Bristol shows the benefit of the dark skies at AstroCamp enabling an equivalent image in terms of signal-to-noise ratio to be acquired in less than a third of the total exposure time. The higher resolution of the STL-6303E/CDK 12.5 system at AstroCamp can be seen although it is not as significant as might be expected. This is probably explained by a combination of poor seeing at AstroCamp over the three nights of acquisition and the high precision guiding by the Starlight Xpress Active Optics unit attached to the system in Bristol.
