So I realize I still don't have the right lens for this, but I'm giving it a go Question though. What would make a meteor/satellite star trail be a lumpy line? Check out the top of this one at full resolution. (see link)

Might be rotating and hitting the sun differently as it does.
You can see this happen if you watch satellites as they go overhead, sometimes you will get an Iridium flare when the sun hits it just right and it will briefly shine very bright. Doesn't always happen and I'm not even saying that is what happened in your pic, but its a possibility |

everyone in my house is fighting a bug right now, but its clear outside for the first time in weeks, unless something goes very wrong I'm going to try and do some shots. I'm already got most of my stuff setup.

So, do you guys think it would be better to use my 18-55 f/3.5-5.6 kit lens and a much longer exposure? I do that for aurora, but haven't tried it for stars.
I will admit I am tempted to use my 70-300 and a long exposure to try to zoom in a bit since I don't have a telescope I can use. |

NP, that "lumpyness" might be to the meteor flaring as it traveled through the atmosphere. Meteors are lit by their own fire, not the sun.
As far as lenses for big-sky night shots, I use either the 11-16, the 24-120 (at 24), or the 35 prime. I want the sharpness I get with the 35 but the focal length of the 11. Plus, the 35 if f/1.8, the 11-16 is f/2.8, and the 24-120 is f/4. This is the 11-16 at 11mm, f/2.8, 94 seconds, ISO100. I usually do night exposures with the intervalometer and then stack 'em, but wanted to try an ISS transit in one shot. Clouds screwed me over (that's a plane that's making the line). CloudStream by FredMan, on Flickr This one is 11mm, 20 sec, F/2.8, ISO400 DSC_3657-Melk Weg by FredMan, on Flickr How long an exposure are you talking about? This is 240 15-second frames. StarTrails Stack 11mm 2016-03-15a by FredMan, on Flickr And I think this one was 140-ish 10-second frames stacked. Firefly 160527 by FredMan, on Flickr |

CloudStream by FredMan, on Flickr View Quote Neat shot And that makes sense. If I had the budget for another lens, I'd buy the 35mm or something wider in a heartbeat. Just kinda stuck on a $0 budget at the moment. I just caught the 94 second exposure though. Damn. |

Lightroom edits were playing around with exposure, temp, clarity, vibrance, saturation, tone curves, and sharpness. Plus some moderate cropping. Just shows what shooting raw and some judicious editing can do for dramatic presence in a photo. CloudStream by FredMan, on Flickr |

finally got my clear night. I'm surrounded by trees, light pollution is pretty bad too but it was night http://i.imgur.com/GO3NDuo.jpg View Quote Jelly. If I had a drive I'd never come inside after dark. |

I'll post pics up once I work on them, my damn guide scope wouldn't work, so I wasn't getting as long of exposures as I wanted without star trails.
|
|
The biggest problem I have is not having the time to learn how to properly use all this gear I have. I can watch a million videos on cloudy nights but when I only get a night here or there to really play its hard to remember it all.
Anyways I'll post up my pics even if they suck I shot Orion Nebula, the Flame Nebula, M31, M33 and Uranus Part of the reason I shot so much instead of focusing on one target was because of the damn trees, I only had a short window to shoot each one |

Thank you for posting this. I was quite the astronomer when I was a kid with my little reflector. It was cool staying up all night viewing the skies and writing notes on my observations. Thanks for bringing it back.

Ciraxis, those are amazing. Are those single frames or are you stacking multiples?

Ciraxis, those are amazing. Are those single frames or are you stacking multiples? View Quote thanks. I still have a ton to improve upon, mainly in how well I can get the tracking going on my mount. each "shot" is stacked. Andromeda and M33 are both about 50 shots, all with short exposures between 10-30 seconds. when the tracking is refinded on my mount I'll be looking to get at least 1-3 minutes, 10+ if my guide scope is tracking well. So yeah I still have much to improve. I imagine I'll get into stacking hundreds of shots in the near future. Last night was mostly a play night, I wasn't going to fuss too much |

Beautiful pics guys. I have zero skill, and limited equipment, when it comes to this stuff. Someday....

I may have already posted this but this website
http://www.jshine.net/astronomy/dark_sky/ is great for finding a dark site for observing or doing photos. There is a great app too |

Thanks, I,ve used that site. I was just wondering where in Va , since I live in the state also.

I put in the order today for the 24mm rokinon. Got 7 days free from lensrentals, so I'll have it tomorrow through 1/3 for $70. Now clouds should move in permanently.

Did you have a chance to play with that lens yet? Been so cloudy/foggy. Tomorrow is Clear and above average, I am packing up everything and shooting from astronomical twilight until i pass out. This is the best so far, this was Christmas evening. 50-60 degrees and dead calm fog fog fog. _DSC3608-Edit by sseagle, on Flickr ETA: The only issue so far is the 'Depth of Field band' on the one I got sent is rotating freely, I guess its good I don't really look at it, and I let them know so hopefully I am not buying this example lol. |

Just got back from my sixish hours of driving, I did manage a nap while the intervalometer worked, but I am beat and real processing/stacking is going to have to wait, I have a breakfast date with my parents.

One "trick" I use for my startrails shots is to take a bunch of short-exposure (10-15 second) shots and stack them with StarTrails. That preserves the "darkness" of the night sky and still gives you nice bright trails. Yes, most are with the Tokina 11-16. This is a 244-second single exposure of the ISS transit. See how "light" the night sky is? ISS Transit 2016-10-17 by FredMan, on Flickr This is probably 20 10-second exposures, stacked. See how nice and dark the sky is?
