Same here, got up at 9pm :V

Thinking of getting a 80mm or 72mm ED-APO refractor, or possibly a 130mm reflector with a carbon fiber tube.
holy fuck just saw the moon while driving to work. sadly I have early shift otherwise I'd take some pictures as well.
A little late to the party due to having a lot of trouble with all the god damn images and figuring out how to actually assemble time lapses (ended up using virtualdub)

The best I could manage.
Conditions were perfect, however it was my first time doing time lapses of any sort and somewhat of a learning experience.
I'd have done a lot differently.
Having only two 16gb cards limited me a lot; I had to make shorter, lower framerate time lapses than I would have liked.
Fairly pleased with my exposures however, which is always going to be tricky when the light levels change this much while the camera is set to a fixed exposure throughout.
I aimed to overexpose the fully lit moon enough that at peak eclipse it would be correctly exposed, and I think I pretty much nailed that.

thanks youtube for destroying the gradients
CRS-8 got rescheduled to early January...
btw NASA's apollo photo project just dumped a lot of magazines of photos (8800) from the apollo 11-17 missions

Thought i could post this, some nebula art i did a while ago.

Finally purchased Pixinsight so I could process my Iris Nebula.. 270€ well spent.

Beautiful stuff!
I haven't been able to use my telescope or do any astrophotography lately, after I moved to inner Oslo. No space + too much light pollution :(

Traitor of motherscope.
I am sorry please don't hurt me :ohno:

WIP Deer Lick group with ~4 hours of data. Processing went a bit wrong ("burnt out" stars) but it doesn't matter since I'm going to shoot more data tomorrow night. I quickly counted 19 galaxies in the pic.
i own a celestron nexstar 5se and i want to get into astrophotography. what is the cheapest camera i can buy with proper exposure and other stuff that i would need?
The cheapest? Well how cheap are we talking here? Theoretically the cheapest camera is the cheapest one you can find a T-ring for, but would you really want to do AP with that kind of a camera?
You can find used cameras from the canon EOS line for good prices, they are pretty good for AP. DSLRs are generally pretty good, if you have a 5se which is a fairly slow focal ratio schmidt-cassegrain on an alt-azimuth mount, I assume you want to image planets.
You can pick up a Celestron NexImage for about $100, its a pretty well-reviewed camera and it will do fine for planets. Another slightly more expensive one (like $5 more) will give you 1280x1024 res as opposed to 1280x720 of the neximage, is the orion starshoot IV imaging camera.
If you wanted to do deep sky imaging, luckily you got a nexstar with a built in wedge that you can use to turn it into an equatorial mount, although its going to be really hard to polar align properly. For that you pretty much want a DSLR of the canon variety, you can sometimes find things like a used canon EOS XSI for $100. The nexstar probably already has a threaded barrel so you probably just need a T-ring that can mate a DSLR to the barrel of the telescope, if it doesnt have threads you need a T-adapter that can clamp in there. You also want some way to trigger the camera remotely without touching it.
Just a forewarning though, the nexstar 5se isnt that good for deep sky imaging for a few reasons, it wont gather that much light despite its aperture because of the long focal length, and its tracking wont let you do exposures much longer than 60 seconds even in equatorial mode without a guiding camera.

Is this one going to be a barge landing as well?
SpaceX has started accepting internship and job applications for their satellite factory here in Seattle. Apparently they might be visiting our club soon (more of a general ME dept visit, but they gave us free merch last time!). I really want to ask one of their engineers some technical detailed questions but I'm worried I'll be out of bounds or that they'll just sent HR reps or something.

Are you serious? I just moved here for school. This is very exciting.

UW? They prefer 3.5GPA plus, along with experience in the construction and design of electronics, the engineering process, etc. Its very hard to get an internship as a freshman, but its worth a shot.
Did some AP with a different setup, this time I used a 60mm zoom lens on a DSLR mounted directly to the telescope mount, meant for wide field imaging. The results turned out pretty good and I loved the usability of it. The ability to zoom is pretty great in AP, and the camera and lens were just so light.
On the other hand focusing is more difficult, and all the images in this are slightly out of focus.

Orion nebula

lower half of the constellation of Orion, with Orion nebula, and flame nebula and horsehead visible as the barest of smudges.
These are all single 15 second exposures, so with stacking I think it is possible to view some very very dim objects.
Honestly screw the super expensive 70mm APO telescopes, there is this one 60mm, 70-300mm focal length APO camera lens that takes some spectacular photos, I might just get that.
I've started to get a bit into stargazing and a couple of nights ago I saw a slow moving, dull red light that flashed every few seconds, It was moving too slow to be a plane or helicopter (plus I couldn't hear any plane noises on a quiet night) and after checking a few videos I don't think it was an Iridium Flare. any ideas what it might have been?
[editline]22nd December 2015[/editline]
It was a single red dot too, definitely not a plane's light.
