It looks (and should look) quite blue. How accurate are the colors?
Very interesting! Did you study anything space related in college or is this just a hobby? Just curious.jedishrfu said:Considering the situation are the suit and mask a little bit overkill?
What if you made a fish tank glovebox container to limit the dust while you work on it?

Tom.G said:How about machining the heads to be thinner? Also, I can't tell for sure but, it looks like there is a shoulder under the heads that could also be machined off.
"Machining" can be nothing more than some tedious work with a file.
Worst case, if there is a shoulder to remove, you may need to shorten the threaded portion to avoid interference somewhere.

Stainless is not one thing. It's a whole family of alloys. Some are better in this regard than others.
At this point I can't remember if my C11 came with knobs or if I retrofitted it, but either way I agree they are a huge benefit for collimation. For me it's about fumbling around in the dark to find the knob (instead of fumbling around with a screwdriver). Potential solution: add a stand-off insert to the lens cap by epoxying --anything to it. Pieces of wood, nuts, whatever. You only need a few mm.collinsmark said:Figure 5. Demostration that they stick out past the lip. Sorry about the bad focus here, I was using my cell phone camera.
I can tell when I put the lens cap on the telescope, that it teeter-totters on the Bobs Knobs. That's not a big deal if I'm just leaving the scope outside for the night, covering it up with the TeleGizmos cover. But it is a huge deal if I ever need to tear down the setup.
Conclusion:
I will not be keeping this Bob's Knobs configuration (sorry, Bob). While Bob's Knobs might work fine for some people on some scopes, it's not for me on my telescope.
