Turn your camera lens into a grab and go

Recommended Posts

A nice idea but a rather expensive way of making a scope. At £1050 for a Canon 300 F4 lens, much cheaper and better to buy a telescope. It is although a solution to mounting a guide camera on a camera lens (QHY5 or similar) to act as a guidescope. I used a similar arrangement to convert an old Sigma 400mm - Canon fit lens to act as a cheap guidescope and it works a treat.

My 300mm f/4 cost about £70. For a few quid more I will have a grab-and-go refractor. Or turn a 50mm lens into an electronic finder...

so can you find me a high quality f4 refractor that can do imaging as well as visual for <1000???

I dont think themos was suggesting that anyone buy a canon lens for the purpose.. but asked if anyone had a suitable lens already...

and it is as a 'secondary' grab and go solution rather than a primary setup...

My worry would be that the rear lens covers are often not too tight a fit.. so half decent ep's are at risk... but some duct tape could cover that.

Thanks for the link themos, something I have 'toyed' with myself.

oooh. nice idea. I have a Nikon f/4 300mm that doesn't get as much use as it should...

Some fun with lens caps and epoxy coming up I think :headbang:
