I have had terrible difficulty getting planetary images so, with Mars high in the sky, now is the time to sort it out!
First step – obtain focus.
. The following photo shows the point at which this combination obtains focus when the telescope is in my lounge and I have aimed it at roof on neighbour’s house at end of garden about 150m away – the furthest terrestrial object I can see from my gouse/garden.
Obtaining focus with similar setup and location and object but using 35mm extension tube instead.
