82 buck Walmart lens

Adapted my 10 year old niece's 82$ Walmart astro scope to the K20D so she could try her luck on the feeder birds. I figure it's about a 500mm F/8 glass. The only data given is that it's made in Viet Nam. Distance about 20 feet.

Full frame and crop with some PP.

I post without comment.

Geez wildman, You could take a good (great) bird shot with a Coke bottle at the end of a cardboard tube. Nice work.

He wouldn't even need the coke bottle. He would use some glass he had lying around!

Makes me want to try adapting the telescope my brother gave me. Any suggestions as to making a mount?

Very surprised by the image quality. While it may be much less convenient to use than a traditional low cost telephoto (aperture control, focus distance, etc), I'd be very happy with the image quality. Have a link of the scope, or a photo of the setup?

She was only here for one day visit so she took the scope home but here's the adapter setup.

Because it's an astro style scope adapting it to a dslr is easy. All you need is 1.25 inch barrel on one end a T ring on the other and a T thread extension tube in the middle. About 35 bucks max.

I've got a 1000mm mirror lens for that. Works pretty well, but a total pain to focus, as the image wobbles quite a bit in the viewfinder...

Thanks for the picture Wildman, now I all I need to do is get the parts.

Do you really have a source for these items in the 35.00 range? I have a 6" Newtonian reflector and have been meaning to break it out for moon shots. This kind of has me intrigued.

Help me out here... that looks like:

T-mount SLR camera adapter: AC486
1.25" standard T-mount SLR camera adapter: AC457
T-mount Extension Tube: AC330

For these part number see: Adaptors for telescopes

Why is the T-mount Extension Tube necessary? Why not do this:



Looks like alternatively, I could go with this unit and this Pentax adapter:

Tele Vue 1.25" Camera Adapter ACM-1250 - OPT Telescopes
Celestron - T-Ring for Pentax K-Mount - Model Number: CE-93403 - $15.95

Or perhaps these - this is really close to the $35.00.

Nicely done, a very impressive shot using materials that don't cost $$$$$. Any more samples to post?

This photo is great...

I have to know more about this "walmart scope". Is it a refractor or reflector? Do you remember the color of the optical tube, make, aperture, anything about it?

Might you be speaking with the family members of your neice again, and be able to find a make, size, etc?

TIA

I have been looking into using a refractor as a long tele for my K10d for some time now.

A comparison.

My TOU/FIVE STAR 500mm f/8.

Looks like I need to cough up 80 bucks!
