A Computer for Astronomy

I finally reached the point of having to buy a better computer. I usually don't spend money on computers much because things change so rapidly and I can get by with older machines for quite a while. But getting into imaging and working with images placed some demands on my needs.

I purchased the Dell Inspiron N5030 from Walmart. This is a very basic laptop with a 320 gig hard drive and 3 gigs of RAM and comes equipped with Windows 7 Home Edition (64 bit).

I have loaded this laptop pretty much for astro usage. I have Deep Sky Stacker which is used for stacking images, as well as Canon Utilities (for the camera driver for my DSLR), BackyardEOS for image acquisition from the DSLR, and PHD Guiding to perform my autoguiding functions.

Additionally I have added some other things. I have installed Stellarium which is a very nice planetarium program, Adobe Photoshop CS5 for processing images, Autostar Envisiage for use with my DSI, and AutoStar Suite for mount control and positioning. Since this laptop came without a serial port, I also added a Keyspan USB to RS-232 to it as well.

I approach computers as nothing but a tool. It should serve some useful function, and in this case it has a purpose. And I really felt the need to move to Windows 7 as most new things will come equipped to use it, and it is a modern operating system with some shelf life to it. After all, we have extracted almost 10 years out of Windows XP at this stage and soon it will be going away. It was simply time to move on and modernize and look at it as an investment into the usefulness of my gear.
