Hi members of Cloudy Nights,
For my first post at this forum, I would like to charter your advice on buying a second-hand Vixen Sensor R-200S 200/1000 reflector. See some pictures from the add attached.
I've been considering expanding my astro arsenal with a large reflector, but I'm not quite ready to spend upwards of €500-600 considering the fact that those scopes are usually not very portable, I live in a heavily light-polluted city (Bortle 8-9) and do not own a car. However, when I saw this add I figured this might be a good way to get into the reflector-game without breaking the bank.
Some things that I would love to ask your advice on:
- Do you have any experience with this scope? From the limited information I can find online, the reviews seem pretty good (although apparently there may be some issues with in-tube reflections).
- I'm wondering how this type of focuser works. It seems to be sliding from left to right instead of up and down. What are these called? And what are your thoughts on these focusers?
- The scope appears to have a 0.965" focuser. I only own 1.25" eyepieces and I'm not sure the telescope comes with the original 0.965" eyepieces. There are various adapters for sale (0.965"-->1.25"). What will be the effect of using such an adapter, compared to a regular 1.25" setup? I'm assuming the FOV will be smaller and/or the image will be less bright. Will the edges of the 1.25" eyepiece be 'blacked out' due to a lack of light at the area between 0.965" and 1.25"?
- Finally: what would you say is a reasonable price for such a scope (including a mount; I have not yet verified if it's an original Vixen Sensor mount though), assuming it is in a 'usable' condition (as you would expect for a 30 [?] year old scope) and the mirrors are in good shape? Right now I'm considering offering +/- €250 for the whole package, depending on the actual state of the scope (esp. the mirror), of course.
Thank you so much for your help!
