Q. I have vision problems that make it hard for me to look through an eyepiece, but I can see images on a video monitor clearly. Eventually, I'd like to end up with something that uses eyepiece projection and is wireless, but to start I'd just like to identify possible video cameras. It would be best if the camera was at least as sensitive as the human eye. I plan to use it on my Meade ETX-90.
A. Bright light objects like moon, planets--any good video camera. Even a webcam like the 3Com Home Connect USB webcam (older model shaped like bar of soap, originally the Vicam) is best webcam for WinXP ever made.

Now sold as the Digi Watchport v3.

A webcam to 1.25 adapter type 2 from Agenaastro can be screwed on in place of the webcam lens.

Supercircuits have some very sensitive (0.0001 lux!) TV cameras that are ultra-miniature, low power, standard B&W and some color ones too,
There are many bright object cameras, either for astronomy or for webcam use that can be used. Adiriondack Astronomy sells Stellacam and many others. Orion Telescope has some USB type cameras for solar system objects.
For faint stuff is the Rock Mallin custom Mallincam models or the Samsung SDC-435 or the A-2333. These are supersensitive ones for faint objects like star clusters, star clouds, galaxies for use with 80mm to 620mm diameter telescopes with the Agenaastro Blue Fireball C-mount to 1.25 inch adapter. You can make a remote control box from instructions at the Yahoo Group sdc435club.
For the true fanatic, there is the Collins I3 electronic eyepiece that is an image intensifier. It can be matched to a video camera. Expensive!
There have been guys taking a Gen3 image intensifier night scope and putting it behind a telescope for remarkable views and not much expense.
Go to www.nightskiesnetwork.com to see live video astronomy most USA evenings and some daytimes from amateur astronomers around the world (USA, Australia, NZ, South Africa, Europe).
Most of these cameras can be used with an eyepiece projection adapter from Orion Telescope. Either a male C-mount to female T-mount adapter or 1.25 inch tube is used.
Wireless video transmitting can be done with several 900mhz to 2.6ghz transmitter/receiver sets from X10 and several other companies for a moderate cost. You don't need the HD or HDMI fancy ones, as the source is SD.
Can I play my tablet over the TV?
Q. I have a samsung galaxy tab, is there any why I can hook this up to my TV to stream movies?
A. Hi Wade, LG WRman Greg here,
It really depends on the model of the TV and the compatibility between the TV and tablet. If you own an LG 3D TV (LM-series), there's the WiDi function which will let you connect the tablet with the TV wirelessly. The new lineup for 2013 will also have a built-in mirror card that can let you connect your tablets and smartphones directly to the TV. However, if this is not the case, then you would need either a microHDMI to HDMI or a HDMI cable, and perhaps an adapter to connect the tablet to the HDMI cable that leads to your TV in order to mirror the tablet's screen.

Is there a way to add RCA inputs on my PC?
Q. My Specs:
Intel Core 2 Duo E6300 1.86Ghz CPU
Galaxy GeForce GT 440 2 GB DDR3 PCI Express 2.0 DVI/VGA Graphics Card (44GPF4DC3FFZ)
6GB PNY Optima RAM
190GB HDD
Intel Desktop Board DG33FB Classic Series Motherboard
Dynex DX-400WPS 400 Watt ATX PCIe SATA PC Power Supply
Samsung SH-222BB/BEBE 22X SATA DVDRW Internal Drive
I mean to be able to plug things like PS3 or blu-ray player into it and see it on my monitor.
A. You might try something like this:

If you're trying to use your computer as a video receiver, HDMI would work. The above link is only for audio, which is another use for RCA inputs. Sounds like maybe you mean to use RCA inputs to receive Component or Composite video signal(s). In which case, I would try something like:
http://www.1stchoicememory.com/catalog/viewitem.asp?ID=38602&r=g&origin=product-search&kwd={keyword}&source=general
This card appears to have a composite video input, which is the style normally having one video signal cable(yellow), and two audio cables(red/white). I'm sure there are other affordable cards similar to this one which can provide you with component RCA inputs(red/green/blue).
