When setting up your "N" network between scope laptop and house computer did you use PC Anywhere program or how do you access the screen and run the "scope software". I'm wondering how you do the computer to computer networking. Thanks. Rick Kuntz MS, CCT CEO CETECH, INC 850-763-8383 cardiofuse@...

I use the new Apple Airport Extreme N router (replaced my old Apple Airport Extreme-snow). I then used Timbuktu to communicate with the IBM laptop connected to my scope via the LAN IP address. Hope this helps. Works fine to about 100 feet or so. Nice to have wireless but requires a laptop at the scope. The CAT 6 arrangement eliminates the laptop at the scope, extends the range to up to 325 feet but requires the one cable. Hope this helps.

I think you need to go into the Firewall program (Norton?), click on Norton Protection Center's Personal Firewall, select configure. Choose Networking tab, click on ADD, and then the button, "using a range" - set your router address range start & end, to include your laptop and any other devices served by your router. I just set it for all 255 devices, in case I add something in the 100 range, or below it. I just trust all addresses behind my router. I did this with my WRT300N as well. Every time I reinstall Norton, I always forget to do this last step. Otherwise, the computers can't see each other or share folders, on the internal wired or wireless LAN. The reason your workaround works is that Norton's Firewall doesn't have the WRT300N's range configured, so the laptop is locked out when it tries it's initial connection. Don't understand why it then works after that, though - Norton should still lock it out. Maybe it's just an initialization step that needs this. Anyway, set the range, and you won't have to fuss with it until the next time you reinstall Norton. Hope this helps, The other Joe (Z.)

Joe, in case it helps, I'm using a Linksys WRT300N wireless-n router and a Linksys WPC300N wireless-n Notebook adapter (PCMCIA card). My observatory computer has W2000 Pro on it and the house computer has Vista. Setting up the home network is kind of "follow you nose" but what I found I need to do each time I start up the observatory computer is to turn off my Personal Firewall in Norton for a few minutes while the network gets established and then everything behaves.

Re: rs 233 to USB conversion
Stuart Heggie <stuart.j.heggie@...>
Thanks! I have a 4 port USB hub on the mount now and everything goes into that and one single USB to the laptop. The appeal of wireless for me is that the laptop is not that powerful but is good for running the imaging session. The house computer is powerful but inconvenient for running the session. Further, I have to cross my driveway and in winter, heavy snowfalls make it a hassle to run wires to the observatory. Still, I think your suggestion is probably best. I will keep it in mind if trouble starts with my wireless setup. Thanks again!

Lunar or Siderial Tracking for Saturday's Moon-Venus Conjunction
drgert1
Hello All,
On Saturday the cirrus clouds prevented deepsky CCD imaging in the Bay Area. However I wanted to make use of the occasion and so I ended up taking pictures with the Canon DSLR of the nice conjunction of the Moon and Venus in the evening sky. For the photos I used a Tak 4" F8 APO and AP0.67x focal reducer. This put the conjunction nicely into the frame of the Canon RebelXT DSLR. Interesting to note that I tried both siderial and lunar tracking for the longer exposure shots of the sequence. The long one at the end of the sequence is 15sec. After comparison I decided that it's more annoying to have dozens of tiny trailed stars that an ever so slightly smeared moon. So I ended up using the siderial tracking shot for the sequence on the web page. I had a lucky shot witht he airplane crossing the moon, too. http://www.trivalleystargazers.org/gert/moon_venus_20070519/moon_venus_20070519.\; html Enjoy, Gert

Joe, could be a coincidence. I went to the AV store where I bought it, described everything I'd done to get it to work and then the chap stared into space for a second then launched into this line of questions about the windows and how new they were etc. I went back, tried moving it down about 2 feet and voila. So, hardly scientific but certainly pretty darn suspicious.

I too found this problem odd - and was very curious why my cheap (G class) Giagafast wireless router (set up as a repeater), was weaker looking directly out of the walkout glass doors, than when I moved it above a bookshelf in the next room (2 feet away). There, it's signal had to go through 2 inches of Styrofoam insulation and a brick wall (and even an 8 inch cube of solid Plexiglas that it was sitting in front of! However, my 1985 sliding door has the old style thermopane glass, not the inner optical metallic coated "E-Glass" filter, so I still wonder if your theory holds. Maybe it's just that the two panes of glass, at a specific spacing, cause the signal of a certain wavelength to get reflected by a greater amount than going through brick walls.

Re: rs 233 to USB conversion

Hi Stuart,

Thanks for the explanation about the Linksys and windows. I too found this problem odd - and was very curious why my cheap (G class) Giagafast wireless router (set up as a repeater), was weaker looking directly out of the walkout glass doors, than when I moved it above a bookshelf in the next room (2 feet away). There, it's signal had to go through 2 inches of Styrofoam insulation and a brick wall (and even an 8 inch cube of solid Plexiglas that it was sitting in front of! However, my 1985 sliding door has the old style thermopane glass, not the inner optical metallic coated "E-Glass" filter, so I still wonder if your theory holds. Maybe it's just that the two panes of glass, at a specific spacing, cause the signal of a certain wavelength to get reflected by a greater amount than going through brick walls. Joe

Dimensions of 600E dec head
Jeff Young <jey@...>
I'm in the process of buying a Mewlon 250 to go on my 600E, but the
mount is in Colorado (and I'm in Ireland). I'm having the Mewlon mounting plate sent to me here (the scope itself will go straight to Colorado), but I need the outer diameter of the dec head, and a brief description of the mouting holes (I have an extra saddle here so I can accurately measure the holes -- I'm just not sure which holes in the saddle line up with holes in the 600's dec head). Thanks, -- Jeff.

Joe, this is very useful information! I have W2000 on the laptop in the observatory and my system does not perform per the promise on the Wireless-N router box. BUT, it works so I'm okay. I didn't realize that the wireless-N card I bought for the laptop is not working as an "N" card. Rats! I'm using VNC Ultra to operate the laptop from the house computer - totally cool.

The good news (for them what are worried) is that my house computer is running Vista so I'm talking Vista<->W2000 and it is working. I was quite worried this would be a problem. Also, I learned something about my new windows (glass/metal type, not computer OS). I put my Linksys router in the window sill to have a line of sight to the observatory and it didn't work at all until it was suggested that the window had a metalized layer to keep heat in the house and when I moved it down so that it had to "look" through the wooden walls, everything started working fine!

To get the Draft-N router range and power improvement, the old laptop need a matching Draft-N NIC card. In order for an old laptop to use the new Draft-N host adapter, it also must be running WIN-XP, since these new cards aren't supported by Win-98/ME etc. If you don't use XP or the Draft-N matching pair, you get the standard wireless G range performance. Depending on where in the house the wireless router is situated you might need a repeater, to get any decent range. I bought one of the new Linksys Draft-N routers but had just a cheap Wireless G type laptop host adapter. With the router at the front of the house, my laptop lost signal as soon as I went out the back door to the yard. I then set up a cheap "GIGAFAST or BLANC" wireless router which I got during their $3 Boxing Day sale, and downloaded the new firmware which now allows it to be used as a Repeater/Router. I parked it on a bookshelf in the back room, and now I get about 70% signal strength all the way to the back fence about 100 feet beyond the house. The signal repeats just fine from the Linksys wireless Draft-N version at the front, through several walls and doorways, and the e house brick wall, to my observing site. Also, Mizzou, if you decide on staying with serial cable, the official range was about 50 feet. Any farther you need to use "shielded twisted pair" cable to get 100 feet or a bit more. After that, you would need an old style modem repeater for the cable. The other way, if staying with cable, is to do the RS-232 to USB, then with shielded cables again, use a USB signal booster device. I suggest you go with a wireless router, and possibly a repeater, if necessary. The Draft-N "matched pair" version might eliminate the need for the repeater, if you are running WIN-XP or (unfortunately) VISTA.

Mizzou - I'm no computer genius but this might be an alternative to messing with cables etc. I have an inexpensive laptop in the observatory, also about 100' away, and a wireless card in it which talks to the wireless router in my house attached to my desktop. It is "wireless N" and reaches the observatory fine. With Pulseguide you could run the mount from inside your house and not run wires.

Declination Knob on tha AP1200GTO
Mike <wildwood7711@...>
I am having trouble adjusting the altitude knob on my mount, yhe set
screw is weak and while turning it to raise the scope the set screw slips off the flat area of the threaded shaft. I have tightened it as much as possible with a hex wrench,it just keeps on working off and free spins. What can be done to prevent this, I do have a 14"ota and other accessories that does accumulate quite a bit weight. Seems like the set screw should have been able to actually enter into the unthreaded shaft my a mere few milimeters.This would prevent shaft damage!I know yhe manual states it is easier to adjust this knob w/o the ota, weights, guide scope attached however it should be able to do so if required.Like everything else it is always harder to go uphill then down. I have wore out the set screw how can I go about getting spares? I am definitely going to need them!

Re: AP155 4 OT
Roland Christen
I guess you can argue in all directions on this subject. My initial
thought remains the same, regardless of drizzling and deconvolution. If you match the size of the pixel to the size of the Airy disc, you will get 90% of the performance of your system. If you undersample, you are throwing away resolution that you cannot get back, even with the fanciest algorithms. Most of the deconvolution processes give you speudo-resolution with telltale "stringing" of the fainter stars. I find that objectionable, but then beauty is in the eye ..... Rolando --- In ap-gto@..., "Joseph M Zawodny" <jmzawodny@...> wrote: Well it depends what you are trying to optimize as well as how wellthe f/2.8 speed should match well with a ~3.75 micron pixel size if youwas to maintain maximum resolution. But the Tak advertises a uniform 10Perhaps a better question is who would buy that scope? What are they tryingto optimize? My guess is that that they are going for large diffusethe diffuse glow relative to the point stellar sources. Another aspectof all of this that has been eluded to but not really focussed on issome of the newer resolution enhancing techniques (drizzling forexample). With these techniques you oversample the optical resolution at highlost resolution due to the inherent pixelization of digital imagery. Itis a lot of work and requires good knowledge of the optical system toof variables to consider when optimizing the imaging system and they goboils down to how much data you have (can take), how good the data(sampling and SNR) is, and how well you understand it.
