... Also note that not all GEMS are going to be good enough for imaging DSOs if you want to eventually go that route. I suggest doing some research on...
Hi Darrell, Wow ... what a hard time you had, but glad you made significant improvements. I have the Orion SkyQuest XX12i IntelliScope Truss Dobsonian, and do...
... The far east solid tube dobs (Orion, Hardin, etc) have two common pinch points on the mirrors. The main one, you found - over tightened primary mirror...
Hi folks! New to this forum, but am very active on numerous others, Cloudy Nights, Astromart, etc. Been active (on and off) in astronomy for several decades....
Thanks John. I appreciate your comments. I've heard a lot of good things about the GEM mounts also. I have an equatorial mount for my 6" reflector, but I am...
... I love astrophotography. I think it's really cool being able to record celestial objects. Using a Dob for imaging can be fun as a novelty, but if you...
Thanks for the information thats just what I wanted to hear. Ordered the xt10i last week, its still not arrived so I think I will have to chase it up tomorrow....
... The 12mm Type 4 Nagler is easily my favorite eyepiece in my XT10 and it reaches focus easily near mid travel. *Note* that this is a 1-1/4" eyepiece and I...
Outstanding EP for the X10! And the used prices have been dropping on Astromart.com with TV Ethos coming out. I never had a problem with mine and there's...
I'm thinking of getting a nice new eyepiece to go with my new scope (the xt10i, when it arrives) and I'm thinking of getting a Nagler 12T4 but I have read...
Hi Gene, The seeing wasn't that great; altitude, I am guessing around 28 degrees or so. Not very high. In my case, light wasn't a problem at all; metering has...
... Wow! The metering kicks in and you get bands. What altitude was Jupiter when you took the shot? Looks like lots of atmospheric refraction (here we go...
FYI, Last week, I did an experiment with an old webcam, 1 1/4" adapter, and a 2x barlow with my 12" Dob. Not sure if I will spend any more money on this...
Hi Gene, It's interesting to hear the comments concerning this problem, but I feel there is some basic explanation that hasn't been uncovered or overlooked...
... O.K. I'm all out of suggestions. Maybe somebody like Dan or Steve or one of the other good guys will come up with something that makes more sense that I...
... It's Fall already, Gene ;) Summer done slipped away. At 7:30 PM Vega is long past culmination, about 45 degrees above the WNW horizon. Steve and Dan both...
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...
... 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...
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,...
... 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....
... 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...
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...
... 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...
... 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...
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...
... 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...
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...
