8" reflector £46 on eBay

[E621Keith]

Someone paid £125 (inc delivery) for it

I feel sorry for the buyer. May be we will see him on here soon asking why his ebay 'bargain' isn't working.

Just thought I would post hear instead of starting a new thread. As these have flat mirrors would it be possible to just replace the mirror with a concave one. That would fix it up surely?

[Moonshane]

they don't have a flat mirror, it is a spherical mirror which is concave. it has not been finished/polished to a parabolic shape which is where the skill and time is in mirror making.a better mirror and secondary would solve the problem but be cheaper to buy a better one in the first place.

Whatever happened to sanmatt?

Would it be possable to put a parabolic mirror in one? And where is the best place to buy one?

[Moonshane]

you might get one from astroboot at scopes'n'skies but to be honest buying a used 8" Newtonian by orion optics, skywatcher or celestron would be more cost effective overall.orion optics and others sell the optics only too but for a basic 8" f4 and secondary it would be about £300 plus VAT and delivery.

Really? Shame, I quite liked reading her posts. I suppose we'd better say no more then...

Thanks for the update.

Oh well. A friend of mine brought one off ebay as his first scope. I just didnt want him to be to gutted when he finds its a dog.

I have never used one but it might not be as bad as people say. it might give decent views of some things. best thing is to encourage your mate to go to a club and see if someone can try and tune it as best as possible and try some good quality eyepieces. it may be at least serviceable. worth a try. hope so.

[valefor]

Hope so too. Il give it a good collomating and try my hyperion on it.

Thanks for the advice. I mite post the results here. As I also have an 8" newt il try to do a comparison
