Terragen QTVR

3 Comments

Terragenâ„¢ includes some neat QuickTime VR tools. Here is my first render of a QTVR scene with Terragen. It’s just a “quick and dirty” scene I whipped up to test. Hold down the left mouse button and drag around the scene to navigate.

You’ll need Apple – QuickTime to view the file.

Last night I created an animation script and started a render projected to take about 15 hours (500 rendered frames). I should have it later today if all goes well… :).

Stay tuned!

Terragen

I’d like to thank davep’s astronomy blog for pointing me to Terragenâ„¢. It’s a program to generate photo-realistic landscapes for Windows and Mac!. I used to muck around with VistaPro in Virtual PC for Mac as it is Windows only (and has an ugly DOS-esque interface). The feature set is very similar but I’m stoked to have a Mac native landscape renderer! Having already been familiar with the concepts from Vista Pro made it very easy to jump right in to Terragen, but I think it would be not too hard to get the hang of anyway.

Although for non-comercial use Terragen can be used for free, I wanted the larger render sizes and the QTVR tools so I plunked down the $99…. erm… ya… thanks Dave! 😛

Here are some scenes I’ve done over the last few days. The initial landscapes are from Terragen and the “special touches” (planets, stars, lens flares, etc) were added in Photoshop CS2. They are not REALLY astro-related but they do have a sci-fi/fantasy kind of theme. Enjoy.






Here are some Vista Pro renders I did a few years ago.




For anyone interested these will probably show up in my next installment of Desktop Images.

Finally LPI!

3 Comments

I think I’m finally getting the Meade Lunar Planetary Imager (LPI) down. This morning the temperature was in the mid 40s F. I got the scope outside about midnight and let it equalize for about an hour. I also uncapped the LPI and put it out there as well… hey the cooler the better with CCDs right? There were some wispy high cirrus clouds but it wasn’t enough to obscure the Moon at any time so I decided to go for it anyway.

Each of these Moon stacks is under 20 frames (the one on the right is 3 I believe) down from about 200 frames each. There was a lot of atmospheric turbulence as usual but I think I got some decent results.





Before switching to the Canon EOS 300D I did about a dozen runs with the LPI on Saturn and achieved what I think is my best shot yet of the ringed planet with the LPI.

I tried to get Saturn with the 2x barlow attached as well but it just wasn’t happening so I gave up after about 15 minutes. I was cold, tired and lacking in patience at this point.

I attached the 300D and at prime focus for what has become my requisite Moon portrait.

More Moon Feb 10

I was getting ready for bed yesterday morning about 1 AM when I realized that sleep is overrated anyway. 🙂

I got set up in the yard by about 2 AM to try some runs with the LPI. It had been in the 50s for a few days now and I thought perhaps the atmosphere would have settled down a bit from Monday… I was wrong. It was still “wobbly” as ever. I managed to glean at least a few shots from the evening and then attached the Canon EOS 300D for the evening’s Moon portrait. After that I pointed at Saturn and took a number of different exposures in order to image both the planet and then to overexpose it in order to grab the large moons. I was successful. Enjoy.

Shots from the LPI:





Lesson learned tonight, take ridiculously long movies with the LPI. Each of the above stacks started off over 300 frames. After aligning and throwing out the blurry/distorted shots, I ended up with only a dozen or so frames each to stack! 🙁 I’m actually considering putting the LPI in the refrigerator for 30 minutes before I go out next time and see if I can’t reduce some of the noise.

Lastly, if you haven’t seen this or been following the comments to this post over at Ian Musgrave’s Astroblog, have a look… there’s something kinda neat cooking.

Well folks, almost every night this week I’ve gotten no more than about 4 hours of sleep — and tonight I had the pleasure of sitting at a car dealership for 4 hours buying a new car (which actually IS a pleasure now that it’s over — as it’s my first “new” car in 18 years).

Adieu, adieu… to yieu and yieu and yieu!
