Hi

I have a Skywatcher Newtonian telescope ( D:200, f:1000) The other day I noticed that the 'O' ring which was attached to the finder scope had broken.  After a bit of digging around, I obtained what I believe is the correct size replacement ( 1.5 mm thickness, 52mm internal diameter).  However, I can't see how it attaches to the finder scope !  Can anyone offer some guidance ?  Many thanks in advance.

Andrew

There is usually a groove which runs around the finderscope that the O ring sits it, then you just push the finder into the bracket.

      Hi, I've got a Skywatcher Heritage 130p reflector, and if i insert anything less than 10mm eyepiece, the image won't get crisp. I guess it's normal, but as I'm very new to astronomy, I'd like to know what the sharpness depends on exactly. 
      Is that the focal length (how fast the telescope is? ) or the size of the mirror and how much light it gathers? Or both affect it the same way?  
      Are things the same with refractors in this regard? Thanks.

      Hi,
       
      So just today i got my new EQ3 mount and tripod delivered.
      Brought it out, balanced it leveled it etc etc.
      So i polar aligned it,  and selected 2 Star Alignment.
      1st star to align to: Betelgeuse.
      As soon as i hit confirm align the motors kick in but as soon as the mount starts to rotate the motors stop and the hand controller resets itself immediatly and starts initializing all over again.
      I discovered that moving Ra on its own works just fine as does moving Dec on its own but whenever i press for example the left and Up arrows at the same time the mount stops and the hand controller resets.
      Could this just be a problem with power draw? The Synpro box takes 12V DC and is supplied by a 12V DC car outlet type power source. However i changed this to a 3 Pin UK 12V 1A DC & AC plug.
       
      Im hoping the power supply is the issue and not something else.

      Hi everyone I am new here, I live in Perth Western Australia (bottle class 5) and have just brought my new set up. There hasn’t been anyone in the area I can talk to about astrophotography so tried to do it all myself online and I fear I may have incorrectly purchased some things. (I tried to get things one at a time for budget purposes)
      I have this set up
      heq5, evostar ed80, .85reducer & corrector, evoguide 50ed, zwo 120mm mini for guiding and just my canon 200d mkii for the imaging. 
      The telescope, I think I may have brought something that’s not great for imaging and that’s all I’ve wanted to do. 
      can you please provide a better telescope alternative that would be suitable for all my other gear without having to buy like a new mount etc. I’m thinking just a slightly better scope not too heavy, opinions would be much appreciated 💖💖💖 xx

      Due to an unfortunate accident my SN10 primary mirror is broken. While it was an unwieldy beast and pretty much required a complete rebuild when I got it from the previous owner I really loved it.  
      My understanding, thanks to discussions between owners of this OTA, is that the SN10 used a spherical mirror. However Meade's representative did not wish to confirm this "proprietary information" after stating that they could not sell me a replacement. 
      So, I'm stuck with a bit of a quandary: do I roll the dice and attempt to get a spherical mirror constructed? (I doubt that non-parabolic mirrors are routinely manufactured and would probably come at a price-premium). I have read anecdotal discussions that the primaries are somehow "matched" to the schmitt correctors which, I must admit, makes no sense to me as I thought that a spherical mirror was manufactured with a uniform curvature. Thus, without more information, I'm thinking that this could be an expensive and ultimately unworkable solution. 
      Alternatively, do I cut my losses and replace it with something like a Skywatcher 250P?
      Any other suggestions? 

      Many thanks for taking the time to read this and for any advice you can render.
