Serial Cable should there be any problem using a spare serial cable that has female ends as a gender adapter?
I bought a usb to serial cable, that has a male end, I used a spare serial cable with female ends as the gender adapter... it isn't working... is this the problem?
If the cable is STRAIGHT THRU you should have no problem.
Their a cables that are not one of these is called a null modem cable meant for hooking two computers together, I suspect this is what you have
dobson telescopes How long would an object such as a planet stay in view on a telescope such as Zhumell Z10 Deluxe Dobson?
I am debating whether to buy an electronic Celestron NexStar 8 SE telescope because of the constant tracking. However, I do like the Zhumell Z10 Deluxe Dobsonian Ultimate because it will have a 10" mirror and is cheaper. I do not have a problem with spending some time searching the exact location of galaxies,planets ext as I do have Google sky map on my cell phone to at least point me in the right direction. I was just wondering how long such objects would stay in view after finding planets, galaxies, ext. Then I will decide whether constant tracking is for me.
Get the 10". Yes, you will need to nudge the scope to counter act the earth's rotation, but the views are worth it. One thing that will help you located objects is to get a telrad.
how long an image will stay in view is a function of your eyepieces field of view. The earth rotates at 15 degrees an hour. If your eyepiece has a field of view of 1 degree, the object will take about 4 minutes to cross from on side to the eyepiece to the other.
