Thanks everyone for the kind words

That is a lovely image.
I like the idea of the wide lens for the landscape. I have done a few MW mosaics and the landscape capture and then process / stitch and align is always the part I feel I don’t have a good handle on. I might have to try it, although I have a planned image coming up that will feature Orion between two prominent local peaks - but it will be just a 3x3 stacked and stitched 20mm mosaic. But maybe I’ll try 40mm on Orion and then switch to 20 on landscape. Fingers crossed weather cooperates. ...Show more →
Go for it! You can try both focal lengths as well for the foreground. Once I realized this method with combining focal lengths, I could get a lot more flexible with compositions. In addition, having two cameras really speeds things up as I can capture the stars and foreground at the same time instead of relying on one after the other and wasting precious minutes for the stars. Good luck!

Great idea and execution on the MW Arch and foreground blend. I might have to get a tracker as I have a great MW arch location for spring/early summer that I have shot and stitched at 14 mm but it gets quite distorted. I need the tracker if I am to shoot at 35 mm without significant star movement.
Now to look for a used tracker on the buy and sell forum!

If you are at all serious about Milky Way photography, I think getting a tracker is the way to go. It turns almost any lens into a viable lens for landscape astrophotography and you can be less worried about having a lens with the largest aperture. Plus being able to stop down to correct lens aberrations is a giant plus.
It is also possible to shoot a Milky Way panorama with a 35mm lens without a tracker (I've done it before with a 58mm f/1.4) and I never had any issues stitching, you just need to keep your exposures short; I think I was shooting at f/1.4, ISO 3200, and like 5 seconds or so. Obviously with a tracker you will be able to stop down and get longer exposures for a better signal to noise ratio, but the result without the tracker was still fairly good in my opinion and you still benefit from the detail from using a longer focal length. Here is an example with this technique; coincidentally the subject in the foreground is also the same in the original post, Courthouse Butte in Sedona.
