What is a “GRAS-003”?
G3 is a high quality Takahashi 150mm refracting telescope located in USA. It has a special astronomy Digital Camera fitted to it called a CCD. G3 can take full color images in a single exposure.
So what happens after I’ve used up my free time?
Absolutely nothing! Unless of course you want to upgrade your account to a full GRAS driver membership that provides access to the entire GRAS telescope network, including the rights to the digital CCD Fits and Tif data from the cameras as well as being able to point the telescopes to any part of the sky yourself.
How do I upgrade my account?
You can upgrade your account at any stage by subscribing to one of our plans HERE
With normal digital photography exposure times are measured in 100th or even 1000th of a second. Astrophotography exposure times are measured in minutes range from 1 to 60 minutes depending on how dim the celestial object is. Most exposure times on G3 are 5 to 10 minutes in length.
Astronomy CCD Digital Camera When the CCD camera takes a long exposure it needs to be cooled down as the main imaging sensor gets very hot. G3 can be cooled down to negative 25C, this allows you to take long exposures otherwise the image would contain lots of noise and wouldn’t look very pleasing to the eye.
You don’t need to know a lot about astronomy to use G3 as very simple to use, just select your target from our One-Click imaging menu, click “Submit” and you start the telescope. G3 will then set the exposure time, move the telescope and image your requested object. Visit the “System Status” link to follow the imaging in progress.
A 10 minute (600 second) exposure needs about 15 minutes of telescope control time. G3 usage is carefully monitored by GRAS Staff. Abuse will result in IP address blockage.
After the process is complete your image is emailed to you directly, so you can share it with your friends and family.
