Yes. About 2hrs after sunset. I don't own an equatorial mount so have to limit exposure times per focal length so star trails don't rear their heads. Hence the stacking.

That's definitely one to be proud of. If you get the chance to do again try shooting it in portrait to get more of the band.

A really nice image. I enjoy getting out to different locations to shoot the milky way, it's just fun. My exposures are single shots only. If I may, I would like to ask a sincere question. What advantages do you see in your stacked images of the milky way over a single exposure of 20 seconds? I'm always looking for helpful hints to improve my astrophotography. Thanks.

Great shot!📷
First off I'm old enough to have been weaned in the film era of the 60's & 70's. I gave up when my film equipment became somewhat obsolete & my career ate up all my time until retirement. So I'm pretty new to this digital business. I began studying astro about a year ago by reading what I could find on the web & a couple books. My understanding of the value of stacking is two fold. First off, stacking increases the values of data by the number of images in the stack. So darks become lighter as more data is put into the final image. Secondly dynamic range is increased by the process. My fascination has been piqued by the fact one can now create images that were impossible in the film days with a camera lens versus a real telescope. It's the sensitivity of the digital equipment that makes the difference. A worthwhile web page is called Lonely Speck. I found it invaluable to read carefully. For a professional explanation of what I've tried to convey you might look up keithwiley.com & go to his section on astrophotography. Hope this helps.
