Astrophotography #1
Yep, I have had astronomy as my hobby for a few years now. But only very recently I made a mistake by trying to take some photos of the planets in our solar system. Those attempts and failures ignited a spark that made me do certain purchases, and here we are:
Here is Saturn, pics taken just tonight in not so great conditions. However I think they succeeded just fine. Unfortunately the ring-angle doesn't allow cassini-division to be seen from earth just now, but at least the rings are visible somehow.

I also took some pics from the moon's craters and mountains.

There's a lot to learn and I'm just a beginner in the astrophotography, but hopefully that stuff just gets better. Not during summer though, as the nights in Funland tend to be too bright for a few months. Luckily around august the nights will allow me to continue the hobby, and as I see it, Jupiter's opposition will be in the early fall.

EDIT: Added one more image...

That first image of Saturn is particularly striking.
Hell, it's all very impressive to my puny human mind since I can't really comprehend the distances involved.

The distances in solar system are not that big. At the time the Saturn pics were taken, Saturn was 9,04 AU away. And by no means Saturn is a small planet to be observed, quite the opposite.

Well, I suppose it's after Saturn that things get considerably farther away, but 1,350,000,000km isn't exactly a 5 minute walk down to the shops :E.

Well, what if I told you (in case you don't already know) that there are stars so big, that if you replaced our sun with such a star, its radius would probably extend to the orbit of saturn. There are a few hypergiants known that could be this big; VY Canis Majoris, WOH G64 and VV Cephei A.

There's a nice video of star sizes on youtube.

Space sure is fascinating. Let us know if you see some saturnians, maybe we can meet them in quake.

With antilag enabled we could play them on a server located between us on a satellite...

on topic: pretty brool pictures co

I wonder who will be the first one to play QW in space! IT JUST HAS TO BE DONE AT SOME POINT!
2010-05-25, 06:23
With antilag enabled, we could just play on their server @ Saturn and still own with lg :-D

Imagine the delayed knockback! They will have to start dodging before they even typed /ready !

Those really are some stunning photographs, Renzo. I would be very interested to hear about (and maybe see, in some further images) the setup you employed.

If you have not already seen, and I would be surprised given the topic is one of your passions, the 2010 five-part BBC series entitled "Wonders of the Solar System" then I would wholeheartedly recommend you take a look.


Looking at the second screengrab is enough to put me right off my boring day job.

Thanks for the update, that's quite a lot of detail right there.

I was hoping that you might already have some photos of your setup perhaps even showing where you go to get your images. If anywhere that is, do you shoot the heavens from your own back yard? If you do have some pictures archived it would save me waiting a couple of months for you to get the kit back out

After we discussed the BBC series I wonder if you would also be kind enough to list some of your own recommendations for my further viewing?

Well, I do have a pic of me and my friend being at the observing site with my telescope, but showing it is a different story

When I'm not at the observing site, I'll just drag the telescope to my balcony and watch southern sky. Also most of the pictures are taken from my balcony, since solar system photography doesn't require specific conditions to be successful, like deepsky photography does (nebulae, galaxies).

So what's the total cost for this hobby so far?
