Hi, I'm trying to figure out what is the difference between RA, DEC vs Azimuth, Altitude difference. I watched dozens of videos and read a lot of material and I think I got it all mixed now.:) From what I understand, if I want to find a star using let's say a telescope than I would need to know RA and DEC which I can get from an app or a chart. (Is there a professional way?) But if I want to point at a star as an observer than I would use an Azimuth and Altitude?
Hello guys as you see i am new in the forums and im starting my stargazing adventure.I want to use my telescope as an astronomical and a terrestrial telescope so preferably a mak or a refractor.My budget is 450 dollars for both telescope and tripod. I already found one good telescope http://skywatcher.com/product/bk-1206az3/ Its the skywatcher 120/600. Let me know if you have any other telescopes.Thank you
This is the first mod to my newly acquired 250px. The teflon pad bearings on the mount are quite simply atrocious for a scope that costs over £400.00 new. Simple solutions are on hand though. Enter the B-Tech BT540 Television Turntable. These were available on Astroboot for a while and Amazon UK but they are currently out of stock. I am sure other brands of a very similar nature are available. This is a 16" bearing with a 75KG load bearing capacity. 1. Remove the dob mount pivot bolt and remove the teflon pads. 2. Remove the sticker centre from the turntable and push out the 2 part fixing so it comes apart. On checking the innards it is quite well made with steel bearings running in 3 channels. The centre hole is the same diameter as the pivot bolt so no machining is necessary. Put the unit back together, you can apply a little contact adhesive to the outer edge, this will aid assembly later. 3. Cut in half the dob mount centre bush. For ease of assembly I glued each half back into the woodwork with some contact adhesive. 4. Obtain a replacement centre pivot bolt that is 30mm longer than the original. Should anyone need one to try this mod let me have your address and I will pop one in the post to you. I only have 3 so it is on a first come basis. 5. Line everything up and reassemble with the new pivot bolt. Total build time about 20 minutes including waiting for the glue to dry and a 10 minute trip to my local nut and bolt shop. Mount is totally transformed, smooth and stable. No machining required whatsoever ..... simples
I have had a Nexstar SLT Goto mount with Maksutov 127mm for nearly two years. It has always had a tendency to lose alignment after a period of use. It's been hard to put a finger on the problem, but AFAIR it never happens during daylight use (solar system align), and mostly happens after an hour or two in the dark, which I take as a signal that it's time to end the session. I just acquired a Starsense which has rather pointed up the problem - great when it works, but last night got this horizontal slippage again. I thought there might be an azimuth clutch I could adjust, but some sources say there isn't one. Any ideas? Or, how much would it cost to get the thing serviced? Or get another used head?
