We've been enjoying some relatively mild temps and clear skies this week, so I thought I'd try my hand at some wide field astrophotography.

Right now I'm using a tripod and a nikon dslr with a 35mm f/1.8 lens. I'm in a town of about 270k, so light pollution is a bit of an issue. Fortunately I've got access to a farm about an hour away that is in the middle of nowhere, so I'm looking forward to some overnight sessions with really dark skies.

Thanks, and yeah that's the top of a 70 foot maple tree. There are two in the back yard, so they managed to sneak in to most of the shots. They lit up like that from a few lit windows in neighbors back yards.

Here's another one that shows more tree, but I think 20sec was a bit too long of an exposure.

Well yes, I managed to figure that part out myself :downs:

I was actually more interested in what constellation/celestial object was being photographed.

Ahh, I see :doh:

I believe that cluster of stars is Pleiades, though I have to admit I didn't really have a target in mind.

We've been planning for a few weeks now to head out to my wife's parents farm in rural Nebraska to watch the meteor shower tonight and do some photography, and now the forecast is nothing but clouds and thunderstorms. :cry: Last few nights would have been perfect too. Still holding onto a shred of hope, but it doesn't look too promising.

I had a blast shooting the eclipse with my cheap 55-300mm telephoto, and I think I'm ready to maybe spend a little more money on something with further reach. It looks like $1k will get me a pretty nice 150-600mm telephoto. Are there any telescopes in that same $1k ballpark that would be good for primarily astrophotography use?

Also I'm sure everyone is sick of them by now, but I'm still stoked about getting some good shots during totality for my first try.

I have this 80mm refractor and I like it quite a bit. https://www.bhphotovideo.com/c/product/735549-REG/Sky_Watcher_S11100_S11100_Pro_80ED_APO.html What's your mount situation though? Because I think for astrophotography, the mount is maybe more important than the telescope. Without a good solid tracking mount you won't be able to do long exposures reliably. You can do up to 300mm or so on a Skytracker (which is what I have) but past that you'll want a dedicated mount.

While we're sharing eclipse photos, here are mine from totality in eastern TN. https://www.flickr.com/photos/jcurbo/albums/72157685154096231



Yeah, I think after further reading I'd be best served with a good tracking mount. I'll check out the Skytracker, any other suggestions around that $1k ballpark? I don't mind spending a little more for something that I can grow into and won't have to replace as soon as I get a decent scope.

You're starting from scratch right? (i.e. no telescope, no mount) Probably the best thing you can do is go poke around Cloudy Nights, specifically the Beginning & Intermediate Imaging subforum. https://www.cloudynights.com/forum/80-beginning-and-intermediate-imaging/ This looks like a good thread: https://www.cloudynights.com/topic/535647-what-is-the-best-cheap-beginner-astrophotography-setup/ and I'm sure there are others.

As for my own recommendations, it's hard for me to say because I jumped straight into a Celestron 8" SCT and Advanced VX mount. (which was like... $1600) If you wanted to stay with your 300mm telephoto you could get a Skytracker Pro, like mentioned before, which is ~$300. I think my main point is don't go buying a dedicated 600mm telephoto lens for your camera instead of looking at dedicated astronomy telescopes and mounts. The Skytracker will start to have issues with anything heavier than camera + 300mm lens anyway, so you'd need an actual mount, which takes us back to my original point.

Thanks, lot of great info at those Cloudy Nights forums. In doing some research I found that we have a good local observatory that regularly hosts astrophotography workshops, so my plan is to get some hands on experience there before spending any money. That should be a great resource for picking up some used gear when I'm ready too.

drat, some incredible shots posted in this last few weeks! You guys are making it really hard to resist going on a spending spree. I'm going to start saving now for an eventual EQ6-R, and build around that. In the meantime I can always get better at star trails and wide angle stuff with the gear I have now.

Sanity check time, have an anniversary coming up in a few months and thinking about surprising my wife with an 8 or 10" dobsonian and a road trip to Devil's Tower for some star gazing (both things she's talked about doing for years now).

First question, how much would I hate myself when it comes time to drag a 10" to a national park? I'm a big dude and I'm pretty sure there are areas to set up not far from parking, but you never know.

Second question, is it reasonable to expect that I'd be able to practice on it for an afternoon and then be able to image at least somewhat competently that same night? Keeping it a surprise is the plan, and I wouldn't have much of a chance to practice with it at home before the trip. I'm not a total novice, but all of my experience in the recent past is with viewing through camera lenses and I've never touched a dobsonian.

Hasselblad posted:

a) Everything is going to be inverted in a DOB, and collimating can be an exercise in frustration.
b) That area is pretty dark sky, and even without a DOB you'd likely see so many stars that you'd literally have trouble making out constelations.
c) a 10" dob will take up a TON of room in a vehicle, and you are likely to throw off the collimation by the time you get to your destination (see 1)

Do you plan to use the dob much at home afterward? Have you considered a sturdy tripod and some astro binocs?

I've got the room in my vehicle, but your points on collimating I hadn't really thought of. I think a dob would get a fair amount of use at home, but now I'm really liking the idea of astro binocs. Time to do a bit of research in that area!

Luneshot posted:

Just to clarify here: in astronomical contexts, "image" or "imaging" usually implies that you are trying to take pictures. Dobsonians are meant for eyepiece viewing. If your primary interest is astrophotography, a Dobsonian is not the right choice.

Right, bad word choice on my part, the plan was for eye piece viewing only. I would like to get into astrophotography with a scope at some point, but not until I can drop enough on a nice tracking equatorial mount. That makes the binocs a great idea though, I could get two pair one like 7x50 or 10x50 for handheld viewing, and something larger for tripod viewing. Then if we're still into it 6 months or a year from now can look into dropping more coin on a scope.

Maybe get a cheap wide(r) field eyepiece like maybe this at 20mm, which is $35 and gives you almost 70 degrees and about a 1 degree field of view for sky sweeping and star clusters and such.

Thanks, I picked up this as well as a red laser collimator by the same company. I'm primarily planning to use this as a visual scope, but won't be able to resist trying photography on it as well.

The path of totality of the 2024 solar eclipse passes over Cleveland and Erie, Pennsylvania, both of which are two hours from Pittsburgh. I have no doubt that it will be cloudy in April. I'm seriously considering going to Texas to see it.

We were lucky enough to be in the path of totality for the 2017 eclipse, and it was hands down the coolest natural experience of my life. I think it would be worth the trip to Texas, but you're probably too late to find decent accommodations super close to totality. In Nebraska at least, in 2017, every hotel room in all the tiny towns were reserved at least a year ahead of time. Saw so many people sleeping in their vehicles wherever they could.

Shameless share from 2017. I wasn't able to make it to totality this year, so didn't bother busting out the equipment for 85%. 2017 eclipse is still one of the coolest experiences of my life.
