So i have purchased a set of Celestron EP's with some filters and upon inspection some of the filters seem to not look overly "clean"? Several of them have what could be best described as water marks whilst another has a piece of something on the filter... Am i able to clean these at all or would it damage them? I haven't got round to checking the EP's but i would hope they are all okay!
Celestron Eyepiece and Filter Kit 1.25in (Purchased from here too)
If anyone has any advice on cleaning them (if possible without damaging them) or what to do that would be great I am not sure what is considered reasonable and what isn't when it comes to this sort of stuff!

I have no idea how this is possible, as I don't take my eyepieces with me anywhere other than outside, but I managed to "misplace" my 10mm eyepiece, which came with the telescope. This may be a blessing in disguise since I can now upgrade it to a higher quality one. That being said....
I'm taking suggestions for quality, but reasonably priced replacements.
Also, I'm curious about this "Luminos" series I see form Celestron. Any thoughts/ideas about them? Are they overpriced, or worth it? If they're worth it, why?
I'm looking at buying a Skyliner 200p scope second-hand, but it doesn't included a mount or eyepieces.
Is it possible to:
- Pair this scope with reasonably a priced mount (<£100) or even a tripod used for birdwatching (do you need a specific mount for this scope?)
- Get an OK set of eyepieces (<£50) used for seeing planets and some beginner DSO.
- Advise me on a telescope mount and eyepieces compatible with the Skyliner 200p for the prices stated above.
The reason i'm asking is because my funds are limited ATM, so i'd like to buy a decent telescope with the intention of upgrading its accessories as funds permit and my astronomical knowledge advances.
Any advice would be greatly appreciated.
So I have recently just gotten the Saxon 200mm reflecting telescope, and with it I received an erecting eyepeice to view terestial objects. Problem is, people are saying to insert into threads and I've tried to do that but it doesn't fit? How do I correctly place the erecting eyepiece onto the telescope? Please help!
Images of regular eyepeice for space objects (28mm) and other parts included to help.
I am putting together an oil-bath auto-collimator rig to check over my reflectors.
It occurred to me to use an off-axis guider body and its pick-off prism to feed the light source in - no heath robinson pipe assembling. Then I can just use a positive eyepiece where the camera should go to examine the ronchi lines to estimate the optics quality.
This raises the question - I would need to put the ronchi screen on the telescope side of the prism - say in a filter mount . Is this too far from the source ? Is the source to ronchi screen distance important ?
