  1. Hmmm. OK, I think what I have to do no matter what is get my hands on my friend's telescope so that I can get a really good alignment set, and try other solutions in conjunction from there too. Thanks for this! No worries! Strange right?? Well, at least I'm glad to know I was also understanding it correctly—that something is wrong. Thanks for helping me think it through, though. True! This is actually a pretty interesting solution... but it seems like it's not something that's going to work with this hand controller, since I think there's no way to isolate just the RA, and also 'lock' the on any coordinate, RA or DEC (which is the whole problem I'm having). Do you recommend using some different method for going about this? Like a specific controller? (Sorry, still so very new with all this!)
  2. Hmmm.... Well, I am not looking through a telescope and noticing, for example, a star drifting in the eyepiece, so to speak. Since I am running these tests inside, I am not actually looking at anything in the sky yet. Maybe I need to explain the problem like this: 1. I proceed through 1 or 2 star alignment process (but since this is happening indoors, I am not adjusting anything and just proceeding through, so it is pointing to a hypothetical "north") 2. Turn on sidereal speed tracking 3. Manually slew to RA 17h 45m 40s / DEC −29° 00′ 28″ 4. Leave it alone for several hours 5. The hand controller now reads something different, now RA 14h 22m 57s / DEC −28° 33′ 31″ So my question is: why isn't it simply staying on the first coordinate? Why would it read something else? It is also quite possible I am simply not understanding your correct observation
  3. I actually hadn't considered this up to now, because for this specific project, it might not be the best solution because there might be times it is unattended (so I guess I am worried about theft...) and it would be nice to keep the whole thing as streamlined as possible. But it's nice to know this can be tried as a possible solution if I can't get my Synscan controller to work. Thanks for the suggestion. Correct, but for now, this is just testing to make sure I understand everything and it is all working—so when I am doing the alignment, I am not making any corrections during the one-star alignment, essentially meaning to the mount that the alignment is perfect. I am indoors just for now (we are getting a lot of rain this spring!) From what I can tell this shouldn't be causing the problems I am having though, right? And just a question because I am just learning about all this (thanks for the help, by the way), couldn't I use something like a Vixen polar meter?
  4. Hi there! I'm a bit of a beginner, please forgive me if I'm not explaining things correctly, I can explain further if needed. I bought a Sky-watcher HEQ5 mount with Synscan (firmware version 04.37.03), with the plan of using it as part of an art/educational exhibition event, so what I'm doing may sound completely nonsensical, but please bear with me knowing this is not for traditional viewing or photography purposes: it's going to be used to illustrate the motion of the earth in relation to the galaxy, so it will run 24-hours a day with a big wooden arrow on it instead of a telescope (it's very lightweight and balanced, of course, and I checked that it won't hit the tripod), running even when the galactic center is below the horizon and the sun it out. It will always be "pointing" to the center. I hope that makes sense. Strange, I know. I have been doing some tests indoors before I use it in this project but I'm running into some issues. The coordinates I want to follow are RA 17h 45m 40s / DEC −29° 00′ 28″, the center of the Milky Way Galaxy. It doesn't appear to exist in any of the object databases in the Synscan (as far as I can tell, from looking in the Simbad database, unless I am wrong?) I'm at 59.9º N, meaning the location is most often below the horizon, so the mount will not slew to it 90% of the time when using the 'user defined objects.' For the sake of my tests, what I have tried to do is to manually slew to the coordinates while the sidereal tracking in on, in the hopes that it will simply follow the motion. However, I am finding a problem: it will start it at the exact coordinates I slew it to (RA 17h 45m 40s / DEC −29° 00′ 28″), but immediately it starts to slowly drift away in the DEC, one arcsecond at a time. For example, now at 12 hours of running, the DEC is at -28º 38' 16" (the RA remains accurate.) Tonight I am going to get up at 5am to do a 'user defined object' test, when the location is above the horizon, to see what happens. But for the sake of convenience, though, I would sure like to have the manual slew/sidereal tracking option work as well. When setting it up, I do just a one-star alignment, but since I am still indoors, I can't visually confirm it's correctness. (But shouldn't that technically not matter? In that the point of the sidereal tracking is to follow coordinates exactly?) Anyone have an idea as to what's going on here? Thanks for your time, everyone!
