If any, what telescope(s) do you own?

[Mr.dobsonian]

Fitting the name, I have a 10" collapsible dob.

How does a collapsible dob work?  I thought the mirror position had to be fairly precise? 

[AlamoVampire]

1. 60mm Celestron refractor -retired

2. 4” Newtonian Reflector from Celestron -shelved but still able to be used

3. Celestron Nexstar 6SE a 6” schmidt-cassegrain -current operational scope

thats my scope collection

The secondary mirror stays aligned with with primary mirror and when the telescope is extended it is also put in line with the eyepiece so you can look through it. Hope that clears things up, reply again if I didn't explain it well.

150 mm Newtonian reflector. It's at this aperture size where additional width results in exponential rise in cost, so that was my sweet spot.  Even though its theoretical maximum useful magnification is 300x which is already the ceiling for observing from the bottom of the atmosphere, I wouldn't mind 250 mm for additional light gathering.
