The Starblast is collimatable. If there is a concern, it is with the weak plastic focuser’s ability to hold the laser steady enough for precise collimation.
Agree. The biggest challenge is the sloppiness of the focuser throwing off the axis of the collimation tool. After much trial and error, I got the secondary positioned and aligned well, which made the primary easy to align with a barlowed laser. Fortunately it holds its collimation pretty well.
The biggest bummer is the focuser slop during use (thus my comment about wishing for a better focuser).
So far it seems to work rather well (the StarBlast and my Vixen HR's). Ironically, the usage issue that is most troublesome is that the 'scope is so small thus breath and body heat end up degrading the image quality unless you're careful. Exhales go directly in front of the nearby tube opening! =)
