Well, yesterday and today I tried my "new" rig. For a couple years now I have used my trusty Sony A77ii with my Minolta 400/4.5 plus 2X TC - that is what I took the previous shot with and all my shots till yesterday.

Now, I am trying out something different. I bought a Kenko Pro 300 3X TC.

Seeing is TERRIBLE for the moon right now with it so low in the sky, but I am so itchy to shoot I have tried anyway. My results tell me that when I get good high clear moon, I am gonna be happy! I almost certainly will resolve more detail.

This with my A77ii + 300/2.8 + 3X TC + 1.4X TC. 1260mm! :twisted:

It works great.... can hardly wait for a clear moon to shoot!!

From just after dusk 11/11/18

Waxing Cresent 19% at just 17 degrees in the sky

Stack of 320 frames.

I had no idea there was a 3X TC made! I only knew about 1.4 and 2.0
I googled Kenko Pro 300 3X but google only found 1.4 and 2.0 which included B&H Video and Adorama.
Where did you get your 3X from?

Excellent shot!!

I searched for, "Kenko Pro 300 3X"...

It appears that places seem to be 'out of stock' right now, but they do make them.

That seems similar, but I think the "manual" version. Mine is a cream colour and it is AF - though it only really works SORT of on my 300/2.8. AF is not its strong point! lol

Thanks! I am REALLY looking forward to a clear high moon! Should be awesome.

I got mine on fleabay for $130 with free delivery. Been looking for a while - they are rare in A-mount. I am not sure they still make them - I had believed not.

Here is one like mine - I don't know what mount it is.

I have tried it out on regular stuff too with my 300... did a couple of "review" image sharing posts on another forum. I could share them here too if there is a place - or just share the links?

Best regards

Mike

Slagrim, with your iEQ45 tracker, does your lens foot mount directly onto the tracker as is, or does it require an adaptor?

Thank you for the link to the one like yours. I just sent the seller a question asking what the mount is.

Please share the links to your other posts.

Mars tonight - just a straight out of the camera hand held shot, then heavily cropped from 6000 pixals to 1800 pixals.

Sorry for late reply. I have Orion 8" f/8 Ritchey-Chretien Astrograph Telescope. It has two dovetail bars on it. (https://www.telescope.​com …60/p/113910.uts​?keyword=8 (external link)). One Losmandy-style, another Vixen style. I took off narrow bar off the tube and bolted to Sigma lens shoe. Now lens and camera on in could be mounted on equatorial mount. That bar like this: https://www.bhphotovid​eo.com …ersal_dovetail_​plate.html (external link) but longer. Mounting holes on the bar fit all lenses shoe (if it has one).

Very interesting shot. Did you hold your breath to snap Mars? I believe your lens was on manual focus mode. Regardless chromatic aberration it is noticeable partial shadow on the disc. Good shot!

It was just a quick shot just to show the wife - I locked focus on the moon then just played with shutter speed and VR till I was able to get a steady shot - but still allow enough light in.
So it was in focus mode but already locked focus on the moon using my back button focus - then I just pressed the shutter.

Hi all,

Last night was the first clear Moonless night for a while, so I drove an hour Southwest of Brisbane and took some test shots of some of the larger deep sky objects to see how my 100mm macro lens performs for astrophotography. These are is 30 x 40 second exposures in a Star Adventurer Mini tracker, with the lens at f/4 and 3200 iso. Processed using DeepSkyStacker and Lightroom 5. Nothing too flash, but something I've been wanting to try for a while...
