Night time filters to cut down the effects of light pollution appear to be relatively new ( found one article suggesting the first generally available ones were marketed in 2018).
Has anyone had experience with them? How effective are they?
The ones from "quality" filter manufacturers seem to cost around £130 for 77mm filter threads or 100mm square. So they appear to be a substantial investment, so real life experiences would be great to hear about, before making a purchase.
I tried astrophotography for the first time this weekend, and have a few questions.
I've read many times that an F4 lens isn't fast enough for astrophotography, but it was my only option this weekend. I think the outcome was far better than I expected, although my "standard" for results probably isn't that high.
Anyway - I tried 30 seconds F4 on approximately 16mm, on a tripod of course. I can see glimpses of the milky way, but not as clearly as the "typical" astro-photo you'd see from an experienced photographer.
Question 1: Which camera settings (shutter speed, aperture, iso) is preferable in order to capture the milky way?
Question 2: Is it not enough with only one photo or are you supposed to stack multiple photos?
Question 3: What is the benefit of stacking photos - will the milky away appear more clearly, or is it to reduce noice?
Feel free to advice me (and other beginners) on how to make the milky way appear more clearly. I'm sure the camera settings should have been different .
I'll throw in a couple of sample images from this weekend. Both are edited in LR.
This is my composite of the eclipse reaching totality. Each photo is about 10 minutes apart until it reaches totality. I love the detail of the sun's corona. Seeing the picture after witnessing the eclipse is incredible. I feel so fortunate to have captured this magical moment.
