... My advice is to not get too frustrated when you try to image with a Dob. It's ok to experiment with, but a GEM mounted scope is a lot more enjoyable. I...

Hi, just thought I would say hello. Today I have placed an order for my first good sized Dob. I have a skywatcher heritage 130p which has given me a good start...
... welcome aboard. Many of us old-timers here also regarded an XT Dob as our "First real scope" . Hope we meet your expectations. And that as you get more...
... Welcome! I consider my XT10i to be the best astronomy purchase I've ever made, and I've made a lot! I still use it several times a month. John Wunderlin...
A couple more questions for you all. With the holidays approaching, does Orion ever put scopes like the XT8 Classic Dob on sale? Does anyone have any...
One more thing to think about is how you'll be set up at the site. The XT8 is rather low to the ground, so you may want to bring an adjustable chair. I also...
... Sometimes. They also do offers for free shipping and such too. I think the latest catalog that I got yesterday had free shipping on every order over...
I was finally able to check the modifications out last night and what a huge improvement! All I have to do is select a target and the object the scope leads me...
Hi Steve, Glad to hear the great news! Yes, isn't a wonderful? Once you learn how to find objects in the sky by the usual, old, but trusted methods, the...
I noticed that the altitude cable jack on my 10 inch Intelliscope has slight play- but it is not loose. Will this affect the accuracy of the COL? Bruce...
... Hi Dan, There is very little play in the jack. It moves barely at all. I noticed it when I was checking if the cables were inserted in the jack. The other...
I guess it would be something to watch through time and use. Is the circuit board secured enough where there's no play? If so, nothing much to worry about. ...
For the past several years I've noticed that I cannot achieve good alignment using Vega and Fomalhaut, never better than 0.6 even if I carefully center them in...
... John, Never tried those two. Tell me, what time of year and what time of night do you typically try that pair? There MAY be a reason. If I find it, I'll...
John, Since the two stars you mentioned are least 91 degrees in separation according to my program I use, ECUPro5, my thought on this would be, if refraction...
... When I first read your answer, Dan, I thought that it might be more reasonable than anything I had thought of (or was about to think of)So I did some...
Hi Gene, That's perfectly okay. BTW, I checked the Intelliscope's manual, page 25, and #10 near the bottom of the page, it talks about refraction. However...
... No. It doesn't. I'll check my numbers again. (I sometimes do that after a couple of glasses of wine with dinner -- posting I mean without double...
... To clarify, I really don't think Fomalhaut is the cause, but rather, Vega. I'm at 35.07 deg latitude, so Sunday night at 7:30 PM, for example, when I last...
John, I just checked my Intelliscope Object Locator for the software version, and it gives v1.49. I purchased my 12" Truss Dobsonian with the locator earlier...
... Try this: http://www.asahi-net.or.jp/~zs3t-tk/aim/aim.htm These are basic equations for doing the change from the one coordinate system (the one attached...
... Dan mentioned places in the sky tha you should keep away from for alignement puposes. The ONLY place that is a problem for an Alt Az mount is the zenith....
Anyway, it is more of a curiosity than a concern. There are always several other alignment stars available, so not being able to use Vega is no problem. Still,...
... The phone jack connectors are designed to have a little give in them. If you want to be sure it's working properly, use the hidden functions to test the...
Hi Gene, I know about these and other equations, but, I don't know what the Intelliscope uses. So, trying to plug info into these and other equations, doesn't...
