I don't think the filter is still made, but a new filter could be made from some optical grade foam (Non Out-gassing)... Or you could sell me the TSC-225 :)...
Mike and Bryan, Thanks for your detailed responses. Informative and helpful. Bryan, re your comments on the secondary and the collimating scope – agreed...
... From what I remember, there is an aluminum hub on the reflective surface of the primary with a piece of cork (?) between it and the reflective surface....
I had asked last week about the back spacing of the Sky90 reducer to try it out with my 6303. I made up an adapter yesterday and got some clear sky last night...
You're welcome! I don't know if the shaft unscrews from your mount. If it does, you may have to tighten it well or use your mount only with the weitghs to the...
Hi Ed: I'll look and see if I can find you a manual, etc. If you ever need a mint TSC-225 Dew shield, I have one. Send me your mail address off line @...
Brilliant Mike! I now feel confident enough to remove the mirror for a proper clean although it won't be for a few weeks as the friend whom I would attempt it...
Andy, From Mike's detailed description of the primary/baffle tube assembly, it sounds like Tak might align and bond a threaded aluminum hub in the mirror's...
Re: 'This sort of interface would allow the mirror to be removed and replaced without disturbing the optical-to-mechanical alignment of the primary mirror to...
Mine was not glued, Fred at TN offered that he put some shellac on it but I can't see how it is needed. One other thing, when you pull the primary out, make a...
I might not soak it, that might be a judgement call when all is said and done...one thing I thought of though and that is making sure everything is completely...
Understood, I'll probably put marks on everything! It did cross my mind to place the tube assembly on it's front end, undo the bolts you refer to then just...
Oh, even easier...but since mine is on mount in observatory...lift straight out, clear baffle, easy enough... ... Mike J. Shade: mshade@... Director,...
I suppose the only danger would be if Takahashi have used a water soluble glue to bond the hub to the primary but I can't imagine this being the case. I agree...
... Similar here especially when we get moisture and then it freezes...have had the observatory freeze open with ice on the rails for the roof, need to close...
Guys, Can anyone suggest a decent artificial star for collimation? I nearly killed myself the other night trying to collimate my Mewlon 250 with one foot on a...
Trouble is, I get so engrossed that I don't notice how cold I've got. The wife's not too impressed though when I crawl into bed at 4am and try and use her as a...
Hi Roland, To use the Tak collimating scope you need a dot in the centre of the secondary. The 250 doesn't have this, the 300 does. Even then, using the...
Roland, AVA (Adirondack Video Astronomy) sells an artificial star (not sure who actually makes them) that works very well and is under $100 complete (I think)....
