RedZoneOS Posted August 22, 2016 Share Posted August 22, 2016 Hello all, Long story Short - I cannot get anything in the sky to focus at all. I tried to look at the moon with a 32mm zhumell eyepiece, and a 25mm meade eyepiece, same result. a really bright white blurry blob. there is no detail at all, its like staring at a fluorescent light bulb from 2 inches away! I can see the focuser "wanting" to focus, but no matter what, I see nothing worth seeing. just joined and am desperately seeking assistance so I can get up and running and start looking up at the heavens and check out other parts of the forum that will help me develop this hobby! I purchased a used 10" skywatcher collapsible dobsonian along with a number of accessories, and I have been struggling to get it to work. condition looks fine. externally its in excellent condition, practically brand new. optically there is some dust, but no visible scratches, cleaning marks, etc. I know nothing of telescopes, but I don't "think" there is anything physically wrong with it. problems (please help with whatever you can!): 1. Collimation - I have never properly collimated a telescope except the very first time I bought a Meade DS-2114ATS way back around 2001. This scope came with a laser collimator so I popped it in. The optics were BADLY out of alignment. the laser beam wasn't even hitting the secondary on the return trip and it was a good 3 inches off center from the primary. I ended up unscrewing the secondary and hand adjusting the mirror. then I unscrewed all of the adjustment screws on the primary until I couldn't anymore before I began even attempting to collimate (maybe this caused my current problems??). I have it now to where I think it is "close enough". The laser beam hits the primary directly on the left edge of the center circle (not dead center). It also hits the center of the collimator on the return trip, however I can see a bit of a red edge on the lower left portion of the black center. This is the best I've managed in 3 weeks so I really do hope its "close enough" haha. 2. spotting scope doesn't align with telescope - there is only one fixed way of attaching the spotting scope, but no matter how much I try to wiggle it around, loosen the adjustment knobs etc, I cannot match it up with the telescope. its not even close. If I point to the moon with my scope (blurry blob), I don't even see the moon in my spotting scope, and vice versa. I tried to follow the manual I found online for this scope, took off the spotting scope completely and set it up from scratch, to no avail, still not even close. I have no idea how to (or if its even possible) to fix this issue. 3. focuser, adapters, and eyepieces - I got a number of eyepieces, filters, and adapters included with the scope. I have no idea what is an additional item, and what came "factory" with the scope. I'll be more specific tomorrow when I get a chance to have my scope right in front of me, but taking a guess for now - the focuser assembly is attached. Then there is some sort of adapter on top of that which I assume is the 2-1.25 eyepiece adapter. and then my eye piece on top of that. I feel like there is 1 additional piece also attached but I can't recall right now... mentioning all this, in case it can be the source of my problems. I know for sure that there are at least 2 separate sets of tightening screws, in addition to one that is below the focuser which allows for finer adjustments (I think) 4. truss tubes - I think I am supposed to pull the tubes out as far as they will go, which is how i have it setup. thought i'd mention it in case I have the tube pulled out "too far" which may be creating my problem? Side note - I have a Meade DS 2114 from 2001. I stopped using that scope after the tracking motor crapped out some time in 2004. This scope has been through hell. trunk of my car with no padding on a road trip from california to illinois. basements, garages, dropped a few times, completely uncovered and unprotected optics for well over 10 years. I pulled it out the other day and literally cleaned off dirt, crust, spider webs, with soap and water, rubbing alcohol, and paper towels. LOL. clearly I don't care at all for this scope.... I am mentioning all this because after ALL THAT, I can still see the moon reasonably well!! This is what has me really really stumped about my new scope!! please help!
