In another post in this forum, I described (with pictures) how I set my Dob up with degree circles for a "Go-To" scope. Last night I got to test it, & it works exceptionally well! After sighting in on Polaris, & turning the Azimuth scale pointer to "0", I set in the Altitude & Azimuth numbers (which I had previously got by rolling up the time to my viewing time in my new astronomy program "Pocket Stars". (It was also set up for my viewing coordinates). I was familiar with M13, so I put in 38degrees Altitude, 074degrees Azimuth, had my Burgess 38mm eyepiece, & looked & WOW! M13 was there. I then "dialed" in M92, & again, there it was.
The only drawback to this system is, of course, with time moving on, the coordinates change; this will be remedied when I get a Palm PDA with Pocket Stars on it. Then the coordinates will be up-to-date.
This "Go'To" is very effective, VERY inexpensive, & no complicated manuals to read, just go, view, enjoy. I wish to give my heartfelt thanks to SkyArcher, & Rod Nabholtz, both spent much of their time walking me thru setting this up & answering dumb questions! Without them, I wouldn't have been able to do this.

Muy bueno! I wouldn't call it "go-to", but the bottom line is it works well, and it didn't cost you anything significant.

Empty wallet, loooong time between incoming $, that's why I love my "Push-To" system!

Carol,
Would you post links to all the instructions you used to make this? I've got a Treo 90 that I could use, and have been wanting such a system for my light polluted skies.

Hi Curtis: In this forum, under "Degree Circles", my post with pictures outlines pretty well what I did. Another nice CN'r made the degree circles for me. The only change I made was on the Azimuth scale. Instead of screwing in the clock hand (pointer)) into the side of the lowest base, I attached with screws about a 12" strip of metal (got it free at lumber yard) strapping metal, to the side of the lowest base with the middle of the strip at the "zero" mark on the degree circle. I then glued the clock hand pointer to a magnet. This sits on the metal strip & can be moved to "zero", when you align with Polaris, without manually moving the complete base around. I used a $10 inclinometer (magnetic base) that I put on the tube, to set the pointer correctly on the Altitude scale. Hope this helps, it's a real effective way to find objects! Also, SkyArcher just posted the degree circles pdf file on my "degree circles" post.

Congratulations Carol. This type of system can be very rewarding and represent a great return on the invested dollar.
I can't imagine not having mine when looking for the faint fuzzies, and I put in years of chart referencing and star hopping and had gotten pretty good at it. I vastly prefer the convenience of my manual push to.
Well Done on yours.

Thanks Rod: You were a great help getting me up & running!
After only one night, I can't imagine going back trying to find something without it. The metal strap worked great, & of course, the price was right again, $0!

Carol, thank you for posting your project, and for everyone who's pitched in with helpful links and comments. I've bookmarked both threads. I don't fully understand (yet) how everything works, but what a great primer on what dsc's are. I hope to replicate this someday soon.

MCH: You are most welcome. It is because of other CN'rs posting what they did that got me interested, & with their expertise, I have a real neat setup, that I'm very proud of!
Also, welcome to the forums!

I took some liberties but the approach is the same. The picture doesn't do it justice due to my camera skills. A special thank you to Skyarcher for the .pdf and Rod for the ideas.

Glad you got use out of the article.

I have a question about the "Pocket Star" program. An object say M13 - on a celestial map it says dec "X" and RA "Y". Will the pocket star say the same thing - X and Y or a calculated Alt and Az based on my location and time?
Thank you

In addition to RA and DEC, It will provide current Altitude and Azimuth for your specific observing location and local time.
Early pioneer's of this ALT AZ circle method used programmable calculators to convert RA and DEC, we just get to point and click.

Plus, this is my favorite type of project. What I like to call a "non-destructive modification". I used no screws, nails or glue. Therefore, it's all easily reversable should I want to. No ripples and I used a 1/4 margin on all the lamination so it shouldn't seperate for years. I didn't do quite as good as you on the materials though, $18 at Kinkos and $10 at Sears.
