I have the iOPtron Sky tracker ($300) with a ballhead ($50) and a $300 tripod.  I use it with a Nikon D7200 and the built-in intervalometer.  No counterweights. I have used it routinely for 120x60 ...

Nice shot of the Pleiades. How long were the exposures and how dark was the sky? hha

I have the iOptron SkyTracker. As delivered the polar scope reticle was mis-aligned about 30 arcmin with the pole axis shaft. I aligned it using a green laser. Now I get the pole aligned to better ...

Very impressive for one hour. From a good dark site? 120 x 30  seconds? hha

Roger: Interesting thread. My result used the D7200 saved as high quality JPG with auto WB. Next time I go to a dark site I will try daylight WB. Your NGC7000 example with the 105mm lens at f/1.4 ...

Rodger: Thanks for you assessment. My objective in this picture was to see how the old 85mm f/1.8 Nikkor lens (deemed to be one of the best in its days), mounted on a newer APC DLSR (D7200) would ...

My objective in this picture was to see how an old Nikkor lens (deemed to be one of the best in its days) in my collection, mounted on a newer APC DLSR (D7200) would perform. I compared the result ...

Interesting that your Canon 6d2 is not modded. You somehow got more deep red response than I got with the D7200. My processing was all done in IRIS and very simple: No darks or flats. At f/2.8 the ...

Improving the red response from a stock DSLR by removing a filter is referred to a “modding” a camera. How do the stock and the modded results compare for comparable exposures? To find out I took ...

That is a fantastic lens. I presume the 6D2 is modded. Last Sunday I took 9 pictures of the same area from Mt. Pinos using a much more modest setup (Nikon D3300 not modded 50mm f/1.4 at f/2.8 ...

With that short a lens you can do 20 second exposures without a sky tracker. Show below is a 30 second exposure with a D3300 iso1600 18mm f/3.5 kit lens at f/3.5 taken two weeks ago on a backpack ...

This sounds too good to be true. Does the manufacturer have a website to support this claim? hha

Very nice for first try. I also have gotten good results using Sequator (with high dynamic range enabled) with no bias and dark frames. What 400 mm lens  and what f-stop did you use? hha

very  nice. hha
