Well not only the angle grinder but also the new neat little Ozito bench grinder and a cute little vice have become just so handy in doing delicate
adjustments to gear.
They enabled me to shorten an extention tube to enable the RASA to reach focus and you know how it goes you order spacers various tubes etc and wait only to find you need something else...It was a desperate move but the angle grinder saved a lot of work such there was little to do by the time I brought in the smooth file and fine sanding medium...The flash gauge I used told me my job was near perfect.
Next was the bracket to hold the EAF... it provided a range of opportunities but was just too long and so bring in the angle grinder and bench grinder, smooth file and sanding paper and it is now a perfect fit..
So last night I tried the Nikon and the 70/200 lens but extended it to about 180 mm focal length...the problem was it was now very difficult to see any stars other than the bright ones I used to focus and finding them was very difficult and then to find an intended object I had to take long for exposures to work out where I was...and nothing worked I got lost and stayed that way until the clouds rolled in prompting me to close up for the night..the idea was to get the camera rolling and go and get the the other scopes working..but no..all for the want of a finder scope.
Anyways today I decided to add a finder scope to the foot which I attach the camera to the mount and by grinding off the foot of the finder scope mount I made it flat to but up on the camera foot.
Very happy with the result so I painted it but its raining so I am not riding to the observstory in the rain to mount it and test it...but here is a photo.
