M51 wide field, Takumar 135mm lens

[Cozzy]

Quick test of the new to me Takumar 135mm lens on a modded Canon 450D, 17 X 2 min subs, lights and darks. Thought I'd try M51. Processed in PS cs2

Looks like a very capable lens.

 

comments welcomed.

thanks for looking

Tim.

Nice! The stars look good and it looks like you've also caught another fuzzy top right. 

I've also got the 135mm but not yet used it for astro.

Nice capture. Well done!

What a wonderful idea. You are totally drawn to what is happening in this shot. Thanks for posting.

Very nice widefield image. You must be pleased with the new lens.

Thanks for looking and the kind words fellow Loungers. I'm very pleased to have purchased this lens and look forward to using it again and maybe keep a lookout for a 200mm and 55mm Takumar to for a nice little set, better start saving.

I have loked at this lens, based on comments here, but i have other requirements so is low on the list 

But

Its getting higher in price and your image may well move it up my list

Very nice image, lens is good

Very nice image, with round stars all the way it seems. Did you stop the lens down or was it at full aperture?

to be honest I can't remember, these were just some quick test images where I had a bit of a gap in the clouds, but I will say the likelihood is yes I would have stopped down, and I did do a slight crop on the image edge due to frame movement in images. hth's a bit.

The stars aren't showing any diffraction spikes so I suspect the lens must have been wide open. Which version of the 135mm lens do you have please? Some produce flatter images than others.

Also, you have another nice galaxy at top right, probably an edge-on spiral.

An impressive image.

Sorry for the late reply I've been working away. The lens is the Super Multi Coated F 3.5 (No 43542 on the manual / auto slider and 4569940 the lens end), from the mid 60's I think.

I'm not 100% sure but I think the other galaxy is M63
