Spectro stuff for sale, best place to advertise?

Hi guys,

Where's the best place to advertise spectro gear?  (Gratings, prisms/wedges, mirrors, lenses, fibres, beamslitters, etc).  Some of the parts obviously lend themselves to telescope/guider building but generally they're quite specialist.  About three dozen bits and bobs (some new and still sealed) that I acquired a year ago and are surplus to my current efforts. Most are Thorlabs, Edmunds, or Optimetrics but I've a bundle of new Surplus Shed lenses too.

I detest Ebay but UK BuySell seems to be mainly 'telescope/mount' orientated.

Anyone got any experience?  Any ideas welcome.

Regards

for sale

Hi Tony,

the ARAS forum has a new for sale section now, "Petites Annonces"  though there are not really many constructors there.

The astronomical_spectroscopy yahoo group probably has more self builders and I see there was a recent ad there for an L200 for example, you could check with Ken who owns the group if it would be acceptable

Also Stargazers Lounge perhaps where there is some interest in spectroscopy ?

for sale

There are a wide variety of things for sale on UKastrobuysell and as it is free there is no harm in putting it up there. It is not all telescopes and mounts.

Why not list your stuff here?

Why not list your stuff here?  Some of us may be interested in it.

Hi Paul,

Hi Paul,

I think he sort of did ;-)  You could PM for details

Fair point.

Fair point.

I was more thinking that having a price list here would be helpful to all concerned.

P.M. already sent.

Spectro

Tony.  I may get to the stage of getting a second Watec video camera, this time, for meteor spectroscopy. I would need a grating and fittings to place in front of the lens.  I'm sure my astro colleagues can help on the fitting aspect, but if you have the items I'd need for that type of work, I would be interested.

Hi Derek

Yes, a Star Analyser seems to be the first step everyone takes.  It mounts as an eyepiece filter would. 

I don't have one but....

I have a new 1" Thorlabs 4* wedge prism (and mounting ring) that can be placed in front of the Star Analyser to improve resolution.  The Star Analyser variant usually retails at £46 plus £8+ for the mount.  I'll probably ask half.  I'm not sure that you need this until you have some experience with the 'simple' Star Analyser first. 

I haven't used this configuration but I'm sure other more experienced members can advise.  Email/PM if you need to chat.

Regards   T

grating for meteor spectroscopy

Meteor spectroscopy is possible with the Star Analyser and a wide field camera

http://www.threehillsobservatory.co.uk/astro/spectra_20.htm

but a grating with higher dispersion would be better  eg 300 or even 600 l/mm depending on the lens focal length and sensor size. Bill Ward would be able to advise on the optimum setup
