Overexposing and underexposing (formally known as Bracketing) is typically a great technique in landscape photography too because it captures as much of the dynamic range as possible. Most DSLRs can bracket right out of the box. Set it up to take 3 exposures (1 underexposed, 1 normal and 1 overexposed) with about 2 or 3 stops in between. Then merge all 3 exposures in Photoshop and you'll get an image with a TON of information embedded in it for you to tweak in post-processing. Also, while I have't tried this, I'd think that using an ND filter in light-polluted areas like this could help a little bit with astrophotography.

There are light pollution reduction filters made specifically for astrophotography. I was shocked at how good these photos were w/o using such a filter. I don't think you ever could have recovered so much of milky way using film w/o a filter in such a polluted sky. (I was certainly never able to.) Googling for an example, amusingly enough, the first link is to the same site: https://www.lonelyspeck.com/hoya-intensifier-review-an-affordable-light-pollution-filter-for-astrophotography/ https://www.lonelyspeck.com/hoya-intensifier-review-an-affor... That filter is not specifically for astrophotography, just one that happens to work well. Here's a discussion of other options: https://www.cloudynights.com/topic/494162-light-pollution-filter/ https://www.cloudynights.com/topic/494162-light-pollution-fi...

Adobe Lightroom can also merge bracketed RAW (DNG) images. That is, you take N DNG images and you get 1 DNG image out, which then preserves more image information that allows you to non-destructively edit the final image. It's available under "Photo Merge > HDR". Unfortunately, it doesn't provide a lot of settings to tweak the merging algorithm, unfortunately.
