Explore Scientific ED80 focus
Hi all,
The above mentioned scope arrived yesterday and a beautiful thing it is. I have just the bare bones OTA as I’m going to build an imaging rig around it. However, when I try to use it visually I can’t achieve focus. Even with the 2 included extension tubes fitted it doesn’t wind out far enough. If I pull the eyepieces several centimetres out of the draw tube I get a focused image.
I don’t have a star diagonal fitted as yet, but will that really make all the difference? And with my DSLR fitted am I going to need even more extension tubes to achieve focus?
