Collimation of a telescope is critical and so you need to be able to easily adjust collimation, particularly of Newtonian telescopes.
It disappoints me not more manufacturers provide the option, or default, of knobs installed on collimation screws for secondary mirrors of Newtonian telescopes. This is 2023 and sure the cost of living is increasing, but the cost of a little knob compared to a screw, if installed at the factory, surely would be trivial?
For my new SkyWatcher Quattro 200p I recently purchased a set of Bobs Knobs from https://telescopes-astronomy.com.au to improve the efficiency of my collimation. Bobs Knobs have been around almost as long as I have been in astronomy, maybe longer! I remember purchasing a set for my LX200 in the early 2000’s. They are simply a set of screws with thumb/finger grip knobs to replace what you would usually have to use hex/allen keys for.
Shown below are the small screws removed from the SkyWatcher Quattro secondary mirror housing, and the Bobs Knobs installed in their place, in the secondary mirror housing.
Having installed Bobs Knobs I am then proceeding with collimation using an OCAL camera. Collimation of the SkyWatcher Quatro is still a work in progress for me. My entire life so far I have collimated Schmidt-Cassegrain telescopes so I’m on a bit of a learning curve with Newtonians TBH.
