As written in the cloudy nights thread. Also I have done these mods before well some of them, here is what I have done so far.
1. Made dew shield, was going to flock the tube but they have the black matt paint much better in this model, so with this no stray light to the secondary.
2. Bob's knobs installed. Also the washer to help keep strain off the secondary. I made them at work and if anyone wants some and is going to snake Valley I will be happy to give them away.
3. Felt tabs for the base to stop the Dob mount from running wild. 3 worked well this time. I have only the picture of what I used and got the strip from bunnings.
4. Small magnet covered not to scratch tube easy to move with different eyepieces. see pic.
5. the old trusty shower cap to keep dust away!!
6. Astrosystems Barlowed laser on the way, had one before and they work great.
That's it for now pretty much covers things, now to save for the Argo Navis and some better eyepieces. Should have them by end of year.
it will be useful to you.
