Yes, my tripod is definitely not up to the task of pointing upwards and slowish shutter speeds.
With big lenses very few are and those that are for sale that are are really expensive. My solution was $50 in materials from the hardware store and a Saturday afternoon building it. Granted my 60lb monster tripod isn't the sleekest ever but probably has a safe load limit over 500lbs (2x4s, 3/4 inch plywood, and 1/2 inch bolts will do that), is rock solid, and if it gets blown over i'm probably also being hit with substantial debris from being out in a hurricane.

Actually the A* 400/2.8 and an on loan MTO 1000mm f/10.

I didn't set out to build one with that capacity it was just a function of the available materials. 2x4s are the cheapest boards and I had some scrap 3/4 inch plywood. Some 1/2 inch bolts because that is what was available in the quantity I needed when I went to build it (I would have used 3/8 inch ones as they were slightly cheaper but they only had 2 in stock and I needed 1 to mount the tripod head), then some square U-bolts to use a clamps. It folds up and the legs collapse plus has the nice brace/shelf for extra stability and a place to set stuff.

Since you asked so nicely here is what it looks like. Sorry it wasn't taken with a 300mm+ lens or even a 300mm+ equilvant lens but is a night time cellphone shot so the image quality sucks.

Lovely as always, and you did an especially good job positioning yourself for the light.

Hardly something worthy of a patent. Nothing unique, innovative, or original, just sturdy and cheap. It isn't light weighing in at about 60 lbs but then I only typically carry a few 10s of feet maybe 300 if I want to go out into the middle of the park behind my house. But it works great for the purpose I constructed it for and even in sustained 10mph winds with the 400mm on it there isn't any shake when doing astro shots.

Hi Mossy

We all know necessity is the mother of invention.
Its fit for purpose and for the budget conscious what more is there

Great images! I especially like the 2nd one of the pardalote! What a beautiful bird and your frame, the timing/bird pose and the bokeh make this image superb!

Thank you very much. It was a tough little bigger to get a clean shot
The little pardlote is tiny, I'd been looking for it for a while as I could hear it. I walked back to the car and it came and posed right in front of me, buzzing around in the tree.

Size makes up for a lot of other shortcomings. I shot the moon with a MTO 1000mm f/10 with a a 2x converter a while back and I know I missed the focus because there was just so damn much shake on the tripod I was using which was not sized appropriately but even given that it is surprisingly detailed even if not sharp. Then lets add in the shake from the shot and I'm surprised it actually isn't worse. I should probably post it here too as 2000mm is above 300mm so why not:

2000mm f/20 shot of the moon (MTO 1000mm f/10 plus a 2x converter)


After creating a heavier sturdier tripod I did go and shoot jupiter at 2000mm with that lens and teleconverter. You can tell there is a great red spot and some strips but that is about it. You really need some big lenses to effectively image the planets.
Hi,

You should go for an equatorial mount for your 400 f/2.8. It deserves much better than Astrotrac and a tripod

Thanks for the feedback. I was in the kayak, which gives a lot of flexibility for composition, since I can maneuver myself for the best light and backgrounds. This is my favorite way to shoot, but I don't get to go out as much as I'd like.

That is the plan eventually but I will need to save up so I don't get in trouble with the wife. I need to get a big one since if you are doing astrophotography you want to have the equatorial rated for about twice what the actual load you will be putting on it. That avoids binding and shake that will ruin images. Right now with astrotracer I can reliably get 20 second images with pinpoint stars. My biggest limitation is that my backyard has a massive amount of light pollution so that even with a light pollution filter in the lens a 20 second exposure at ISO 400 still shows a lot of sky glow. With an equatorial I could easily go up to 3 minutes and knock the ISO down to 100 and maybe get some improvement but it wouldn't be huge. The biggest benefit is that I wouldn't have to re position the camera every few shots.
