Doug,

With a good laptop (display wise) I would just get a good quality S-video cable (all gold ends and good shielding) and probably bite the bullet on the Mallincam USB frame grabber. Yes it's more money than most USB frame grabbers but it does (in the E version - MCV-1E) have the addition of a black level adjustment which really does make images stand out on a good LCD display. This additional capability is not available on any USB frame grabber, it usually requires another piece of gear (video processor or the obsolete Mallincam DVE).

There are S-Video to HDMI adapters/converters but they aren't cheap and don't appear to buy you anything video quality wise over the MCV-1E. With a full remote site setup (no lappy) and the desire to run with minimal power and off of a nice LCD display then maybe the HDMI converter route might make sense.

Using the supplied control cable and a suitable USB-serial adapter (and probably tape the connections together) along with a good S-Video cable and USB frame grabber you can bind them together so they can be stored and rolled out very simply. The next step up from this might be a nice combined control/video (and maybe power if that made sense as well) cable from Zeningeering (who makes the control cable).

Remember that you've always got that second video output on the Mallincam (it's always active) for a composite video connection. This makes a lot of sense for folks who want a small monitor at the scope for focusing or framing and don't want to mess with the primary video connection. You can also use thinner and more flexible video cable for this second monitor if it's going to be close to the camera.

Wow, excellent advice! It so happens that when I placed my order yesterday, I did actually purchase the MCV-1E USB Frame Grabber. I was going to go to a cheaper one on Amazon, but figured I would just go with a higher end grabber.

Hmmmmm, now I am back to considering a Watec 3.5", or similar, monitor to keep at the scope for focusing. Since my laptop will be out of the dew in my shed, I was kind of wondering how I would check focus without running back and forth. I didn't even think about the fact that I would have an extra connection available.

OK, having looked at the Watec 3.5" online for around $400, maybe I can find a small LCD monitor that's a bit cheaper! I wonder if something as cheap as this monitor would work well enough to achieve focus, if not for normal observing?

Doug,

If you are just going to be using the small monitor at the scope for alignment, and focusing i thinkmyoumcan go,cheap. I use a 9" Portable DVD player with composite input and its totally fine. I think I paid $89 for it 6 months ago.

You are going to,have alot of fun with the mallincam. Enjoy!

Al

There's also a 7" LCD monitor with two NTSC inputs (RCA only) for under $40 .
A step above is the excellent Lilliput 7" HD , high definition, with analog and HDMI inputs for around $180 . This has way better definition than the low cost screens , higher contrast , better color reproduction and is used frequently by the pros . Also runs a couple hours on its internal rechargeable battery.

Al, yes, the small monitor would be for alignment and focusing only, I will use my laptop for observing.

Matt, thanks! I was looking at the Lilliput. I may give that one a try later on.

Doug,
Here are a couple more options for a monitor:
http://www.bhphotovideo.com/c/product/224151-REG/Marshall_V_LCD5_6_PRO_V_LCD5...
This is my main monitor used on my scope as pictured.

Another great option is this:
http://www.telescope.com/Orion-StarShoot-LCD-DVR/p/101876.uts?keyword=dvr
Great for use at the focuser and does a great job at recording also.

I have also used a 4" Marshall and a Watec, but these two are my favorites.

Thanks Paul! Man, that LCD/DVR at Orion looks slick. I did not know that such a device existed.

BTW, nice setup. Was that photo taken at the CAV? I haven't been there in years.

You may also try the Pixel "Expert Wireless Live-view remote"

http://www.pixelhk.com/Proshow.aspx?id=111

or the Pixel "LV-122 Wired Live View Remote" .

http://www.pixelhk.com/Proshow.aspx?id=77

They are camera remote and (remote) live-view LCD in one.

I read on the site Orion.
The user has the dissatisfaction about the absence adjust the brightness level.
I search the Internet. There is interesting mobile PAL/NTSC DVR

I don't have any issue with the lack of controls on the LCD/DVR. Neither have any of the people I view with, who normally use Speco, Watec, or Marshall monitors valued at up to a $10,000 HD unit. Matter of fact, most of the people are so impressed they have or soon will purchase one of them.

What is the video-in connector? It seems to be some kind of mini-plug. Can you connect this to a composite video source?

The video connectors (both in and out) are 2.5mm jacks . It comes with a composite video+stereo audio cable (2.5mm jack to 3 RCA connectors, the usual yellow white red).
Includes a battery charger , a rechargeable 3.7v phone style LiPo battery and the AV cable .
It works with SD cards up to 32GB not 16 as I had erroneously stated before .
It also includes a wireless remote (RF based not IR) to start and stop recording .

Orion monitor have a small screen (2,5").
Why two monitors on observations? In Mallincam one video output? Second (S-Video) - the old version.

My opinion. It is better to have one (good!) monitor and a separate DVR (very large capacity, such as the ability to connect USB Hard Disk - 500 GB or 1 TB).

Orion monitor has another. Power - 5 volts. Where to get 5 volts (in a dark place)? Lithium batteries? They will not last long. I have all the equipment for 12 volts and a powerful battery (one).

Ps. Term good monitor (for a dark place, my opinion)
size 7 - 8 "
signal system PAL
LED illuminated backlight
adjustable backlight levels for daytime or night-time use
works on a 12VDC
low power consumption 0.8 -1 W
