So with a Tou 500mm / f8 + 2x TC, you were shooting at F16 ?

Yes, when you factor in the 2 stops lost from the TC.

I have a Five Star f8 I got from Montgomery Wards 25 years or so ago. I hope you do not mind, here is my Focal 2x tc and Five Star of the moon a few months ago, uncropped.

Hi Rob,

the image looks unsharp and contrast is low. BUT I have taken the liberty to run the image through some sharpening routines and it has much more potential, than thought!

I hope you take no offence. After all it is your image. I guess, if you posted a tighter crop around the moon, you could get much more detail out of it.

For comparisson I have attached a shot taken with a semi-Apo small telecope (600mm focal length f/6) + Pentax 2x-L tc. It has only slightly longer focal length and worked at f/12 with the tc.

No I do not mind!

Please critique the shot and the lens!

I absolutely welcome it!

Thank You!

No offense at all taken!

I welcome any improvements all you guys give!

I have been in the game for a while and have learned a lot but I am still learning and will continue to learn.

That is what this forum is all about!

Thank you!

Try stopping the lens down 1 to 3 stops as it should be sharper there. Use the self timer to minimize movement, and/or use a cable release/remote release. Maybe try putting a beanbag or some other bit of weight on the camera/lens to dampen vibrations more. Turn off Shake Reduction as it's designed to be off with a tripod (though it wouldn't hurt just to also try it in case of vibrations, although using a self timer turns off SR). Focus bracket, it could have been focused slightly past infinity for example, so try multiple shots with the focus slightly altered. If your tripod isn't very stable & heavy, you could hang some weight between the legs to help dampen it. If, for some reason, that Teleconverter is really poor with that lens, you might do as well or better without it and then cropping more.

Even though this is an old thread I'm looking at this particular lens (Craigslist link):

Pentax Lens

Think it's worth $50? I like that it apparently has an integral K-mount and not an adapter, so I'm guessing it's from the late '70s, and per the seller it's branded Toyo Optics and was made in Japan. Thanks!

It's not a bad lens and is kind of fun to use. I think it's better than the 5 score. I've seen them for cheaper on $bay, but they might not have had the Pentax mount nor the case. More info:
Five Star 500
and HERE (Search for "500mm f/8 Telephoto Glass"

I was out looking at moon/Venus/Jupiter conjunction and took this shot w/ the Five Star F8.
Converted to grayscale, cropped, sharpened.
