Astrophotography...first attempt
Lens: KA 50 f1.4 Camera: K3 Photo Location: Hilton Head SC ISO: 3200 Shutter Speed: Above 6s Aperture: F1.6 
Posted By: no694terry, 07-19-2015, 04:26 PM

Took a walk down to beach one night, saw the stars. Came back next night hoping for the same skies. With my dusty old 50mm I was able to get my first decent astro photos. I wish i had a wider lens, maybe next time Ill try getting enough shots to stitch something together.

this one is obviously tinkered with in lightroom.

Thanks.

no but i been thinking about getting that hotshoe mounted do hicky. Even at an 8sec exposure, you can zoom in and see stair trails.

Try a 6 sec exposure @ f1.4, 4000 ISO. You'll get more grain from the higher iso, but you should be able to ditch the star trails. If you're looking for a step up, an M28 2.8 is a cheap and nice alternative.

Thanks, those 28's look like they go pretty cheap. I'll have to try one. It's going to be a while before I'm back on a dark beach, but my cottage up in Seagertown, PA has always had terrific skies, even a little north lights on occasion.

Lol... your cottage is only about 2 hrs away from the state park I fish, kayak, and take pictures at (prince gallitzin state park, fallentimber, pa 16639)

I think I-99 is about as close to there as I've been. I take that route to the Poconos and to Maine

99? really? better served mapping out country roads so you can cut out sections of that trip... 99 is a very.... inefficient road. But at the very least 99 isn't a toll road. Back on topic though, the state park I frequent is the darkest sky area near me. There is one state park here in PA that has darker skies, but I don't remember which one (up north and east somewhere).

well, being 4mm wider would give it better light gathering.... but the advantage over the 28 would be marginal at best. Between that lens and the 28 2.8, I'd say go with the better bargain after looking at the lens review section.

Definitely the better way to go then. You won't really see significant differences in light gathering/speed until you go down to a 20mm or wider. The m28 is a nice landscape lens as well... very vibrant color rendition, with some nice clarity. Easy to get accessories for as well @ 49mm, so there are tons of filters, hoods, and caps available.

Dunno if you'll see this tonight, but it's supposed to be mainly clear tonight. If you have a kit lens (18-55mm f/3.5-5.6), I suggest heading out to a clear area with the kit on and a tripod. Set kit lens to 18mm, aperture in camera to f/3.5, shutter time to 6s @iso 6400 or below. You should get some usable shots. Just don't forget to turn off high iso NR and slow shutter NR, as well as anti-shake. If you have a remote, good, if not, just do the self-timer. The kit lens may not be as sharp as the 50 f/1.4, but it's fast enough to manage astro to some extent.
