finally some clear skies again
here is m42, this is my first proper image with the camera i made a while ago
focus was a little bit off

Wow nice picture jonner!
this is the best topic I ever saw

another clear night last night (had some condensation/frost build up on the scope at some points though)
here is markarian's chain
taken with the camera i made, again
probably over 100 galaxies visible in this image (i cba to count though)

6/10 no bonus meteor

in progress image here is 2hrs 30mins of m81 and m82

if you look closely, you can see that stars and galaxies are aligned perfectly as a penis

man, space is crazy

Looking really cool. What resolution are your photos? I could try to put them as a skybox into emps.

most are around 3000x2000, I can go for higher resolutions by stitching multiple shots together like a panoramic though

finished shot of m81 and m82, total 4hr 30mins exposure time

I'm really disappointed with the lack of bonus meteors lately. Keep up the good work though!

Are those planets? Stars? I dont understand anything about our universum

got me a new lens (samyang 135mm f2 http://i.imgur.com/HWWsBUa.jpg)
here is m31 andromeda galaxy with new lens (full res here http://i.imgur.com/Qa8vBvd.jpg)
55x 30s exposures, 28m 30s total exposure time

Just to give some sort of scale to the precision required for these images, this is part of the guiding graph from tonights session. The blue line is error on the RA axis, the red is the DEC axis. RA has more error since this is the one that actually rotates to counter the rotation of the earth. You can see from the scale on the left that the maximum error is about 1 arcsecond. this is roughly 0.000278° which is just under 1 millionth of a full rotation. Since no amount of engineering is going to make gears precise enough for this without being huge and very expensive, I use a technique called guiding which uses a second small camera/telescope to watch stars and continously correct for error, which is what the screenshot is of.
