Can anyone help?

I am selling the following item which I have just listed in the classified section of this forum:

GS 600 - 200mm (8") Newtonian Reflector Telescope w/EQ Mount

I have no idea about telescopes and I have just listed it on behalf of someone who hardly used it because they also know nothing about telescopes... So between us we had trouble writing the ad as we are both novices....

Have I put in all the relevant info into the ad that someone might need when looking to buy this type of equipment?

Cheers and many thanks!

Lisa, wording is fine. Can I suggest a couple of pieces of further info and two further photos.

There is an eyepiece in the focusser - the small one. Undo the thumbscrew and pull it out and see what focal length it is. It will have 10mm or something similar written on it. Tell the reader what that is.

Then look at the finderscope (the little telescope connected to the big scope). Somewhere it should have its magnification and aperture written on it - it is probably "8x50". If you can find that, tell the reader.

Next people want to know the condition of the two mirrors. If you take off the big dust cap (at the focusser, finderscope end, you can see down the tube to the primary mirror (the 8" dia one) at the other end. Take a photo of that which reflects the light coming in the top (so take it a little to one side) and put that photo up.

Next, take the 2"-->1.25" adapter out of the focusser and take a photo through there while light comes through the aperture end - the view is confusing, but it will give an idea of the condition of the secondary mirror - the little oval one that is at a 45 deg angle.

So those two more bits of information and the two photos should help. One more thing - when you look down the focusser towards the secondary mirror, can you see any lens or glass in the way or is it all air? I don't think it will have this extra lens and that is good news. (That is telling us about the question of parabolic or spherical primary mirror)

However, your challenge is that a brand new better version (that GS-630) is selling for $649. I think you will have to go a good bit under that price to get a sale, sorry.

Good luck
Eric
