Some are saying that because of their ‘open’ design, you should dust and clean them regularly, but in my experience, a bit more dust won’t impede the viewing quality at all. Just dust off the primary and secondary mirror, and that’s about it. Reflectors are quite easy for maintenance. If your Dobsonian loses the collimation during one night of usage, you should check the construction of the truss poles, tighten the screws, check the spider of the secondary mirror and the cell where the primary mirror is embedded. With almost all telescopes, you aren’t going to lose the collimation, but please check before every stargazing session. You should have the custom to collimate your Dob before every use, it takes just a couple of minutes to properly collimate both of the mirrors to make sure they are aligned, and your viewing quality is as it should be. I would strongly suggest you buy a laser collimator they are very cheap, they are easy to use and speed up the collimation process. Other non-collapsible tube scopes aren’t prone to mirror skew. Most of the Dobsonian reflectors require collimation before every use. That coupled with a nice set of narrowband filters, your Orion scope will be all you’ll ever need for occasional stargazing. That’s why I would recommend buying at least the cheap aspherical eyepieces for start, and later you should definitely buy one high-end eyepiece between 10 mm and 25 mm with an ultra-wide apparent field of view at around 100°.
The first one is a 10 mm Plossl, which is complete nonsense and the 35 mm, 2” Plossl is somewhat useful for larger DSO, but you won’t get much of a contrast with it. The rocker base (mount) disassembles into smaller parts as well without the requirement for any tools.Įven with this scope, there are two eyepieces in the box. This is a much more compact version of a Dobsonian reflecting telescope than the previously mentioned Sky-Watcher scopes.įirst of all, the tube disassembles into three segments, one where the primary mirror is, one segment with the secondary mirror, and truss poles as the third part.
I love the disassembling rocker base compact Dobsonians are probably the best reflecting telescopes out there.
