Webcam Astrophotography

Sale Price: $34.95

Description

Over last couple of years webcam astrophotography has literally exploded onto the astronomy scene. It has rapidly evolved from simple black-and-white imaging into long-exposure full-color imaging with quality that rivals more conventional astrophotography. In many cases webcams have become the cameras of choice for lunar and planetary imaging. you can get started in webcam astrophotography very inexpensively. You don't need to invest $10,000 in a high end CCD camera, telescope and software. A basic webcam costs about $100.. Software to control the camera and process the images is free. If you have a telescope (practically any telescope will work) and a computer you are ready.In this Video you will learn:The best webcams to useHow to attach a webcam to your telescope.How to focus your webcamWhat software to useHow to stack and process your imagesand More!This product is manufactured on demand using DVD-R recordable media.

Carnival of New Digital Camera Camcorder

The category of camcorder is one broad category of the old and new, dynamic and basic offing in the world of digital photography. Choosing the best model of a camcorder can be quiet a mission for anyone specially newbies in the photography domain. One of the best camcorders that we are presenting to you in this review is the Panasonic SDR-H80. This one comes with sleek black body. The key merit of the model is that the model has amazing manual controls, 60 GB hard drive and a 70 optical zoom with Stabilization. TO mention some of the quick demerit as though, the Video quality is not the best you can get in the market and the placement of the USB and power input are quiet inconveniently placed behind the battery.

The bottom line is that the Panasonic SDR-H80 has the zoom power of a telescope as well as a lot of storage capacity all in a vey handily compact body. Even if the video results are not that thrilling as you would get with some camcorder models what you will love is that the model has an amazing 70x optical zoom with some stabilization. The Panasonic camcorder model has a CCD optical sensor type. You will get this camcorder model at a price range of $339.00 $501.63.

The Panasonic SDR-H80 camcorder model is a standard-definition camcorder with a 60GB hard drive for storing to a whopping 14 hours of its top and premium quality MPEG-2 video. There's also an SD/SDHC card slot on the side for adding even more storage. Nonetheless the H80's killer thrust is in is its incredibly very long 70x zoom lens, which as it is intended to , as you can imagine, will draw you very close to your subject while you're very far away. The amazing optical image stabilization, although in reality there’s no amount of stabilization that's going to prevent this lens from shaking when the lens is actually extended during performance which is all built into a sleek and compact body. One of the key downsides to it though is that Panasonic has not even in this camcorder model made room for some better video quality for the H80's sub-$400 price.

With the Panasonic camcorder the controls are more typical for this type of camcorder and nothing is so badly positioned to make using the H80 uncomfortable (though the Record button is a touch too close to the battery). There's a Power/Mode dial at the top back for selecting whether you want to record movies or still photos or play them back. Flipping out the LCD exposes a five-way joystick and Menu button on the left side of the screen. If you dread going into menus to make adjustments, Panasonic dots the H80 with several buttons for quickly changing between shooting options. This includes buttons for accessing manual controls, turning on Panasonic's Intelligent Auto (is) mode, and enabling the optical image stabilization (OIS). The last one is particularly handy because you'll want to shut OIS off when the H80's on a tripod.

Exposure time for CCD telescope cameras?

I am considering buying a medium sized telescope for viewing and also astrophotography. I am also probably buying one of the Meade CCD cameras. The question I have is when taking CCD pictures through the telescope does it work like old school astrophotography where you had to have a shutter open for minutes to hours? I ask this beacuse I would love to get one of Meade's Dobsonians (the Intelliscope 8), but that scope does not have motorized tracking. The last time I looked into buying a scope, you had to get a motorized mount to lock onto an object and track it allowing the long exposure to stay on the object. Celestron has a smaller scope (StarSeeker 130mm) that will track, but I wanted something bigger for deeper & fainter objects. Any further tips or info?

Take a look at the Orion XT8, or it's intelliscope version. I prefer Orion to Meade because I have had much better results with the Orion customer service department.!
I also echo the sentiment of not starting into astro-imaging right away. You have a steep enough learning curve ahead of you, just learning to find your way around the sky and how to operate your telescope properly. Get some experience with the new telescope under your belt.!!!
But since you asked the question about imaging, I feel you deserve an answer.
Once you feel totally comfortable with your telescope and the night sky, and you still want to get into imaging, here is the way to proceed:
1. With a little practice you can get some wonderful images of the moon and planets right through your Dobsonian Telescope. All you need is a camera adapter to mount your camera to the scope. Since exposure times would be much less than a second, no guiding is needed.
Once you want to go further than that, things get much different in a hurry.
At that point, the single most important part of your setup will be the mount. Much more important than the Telescope.!!
What most folks don't even think about is that the optical tube of the Dobsonian is nothing more than a plain Newtonian Reflector.
Simply take the optical tube off the Dobsonian mount, take off the azimuth bearings and get a set of scope rings and mount the tube on an Equatorial mount. This makes a very good imaging setup for very little money spend on optics, especially since you have already gotten good use out of it for visual observing.
However, it takes a fairly substantial mount to handle that size of optical tube. The Orion Sirius Mount does a good job here. Take a look at the Orion catalog. If I could afford it, I would even get the Orion Atlas Mount.
(My old 10" Dob optical tube is mounted on the Atlas exactly as described above and takes great images)
These mounts are provided with autoguiding ports to allow long exposure deep space imaging.
Now you've got the scope mounted suitable for imaging. Now what?
Well, you'll need a laptop to run the cameras ( you need another camera for guiding at long exposures), to run the mount, and the software for all this stuff. You also need software to process your images once you take the pictures. Sometimes you need to take dozens of images and combine them to get one final image because otherwise you would have to take exposures which could be hours long!
I think you get an idea why we advise against any imaging until you have quite a bit of time in the saddle with your Telescope.
Anyway, the Orion 8" Dobsonians are excellent value for the money and are very versatile as well as easy to set up and operate, in other words, they are excellent starter Telescopes with the capability of being used for other jobs as you learn the ropes.
