Hi there,

just testing my new webcam with a Celestron 130SLT with plans to take moon avis.

Given the cloudy Melbourne skies (which WILL clear before the weekend!) I tested using the city skyline.

I can achieve focus on the trees across the road but not the city buildings in the 'far' distance. I'm all the way to the lower limit.

So, my question is - will an extension tube or barlow assist or do I have to move the primary mirror up the tube???

Thanks in advance guys.
