How far off does the pointing end up? I have the XX12g, and hence full SynScan GoTo, but often I find that the GoTo gets close, but may be more than 1° off which means that the object is outside the FOV for most of my eyepieces. I thus have to slew around a bit follow star patterns to find the object. Using the SynScan Pro on my iPad allows me to align with each object I go to while connected via WiFi, and that tends get the pointing more accurate.
The pointing is way off. No measurement but significantly off in azimuth, no so bad in altitude. It seems the azimuth is the one that’s off the most. The altitude seems decent but hard to tell with the azimuth off so much, it’s not even close.
If the base is wobbly and/or loose there's no chance the intelliscope function will be accurate. If you think about it just a little you'll see how the uncontrolled base hamstrings the pointing function. When you stabilize it, take particular care to get everything square to the groundboard, the bottom plate to which everything is built. If you can get the back and sides 90 degree square to the ground board and to each other it's likely the intelliscope function may be greatly improved. Check to see that the round pads on which the tube rides up and down are in good shape and that the bosses on the tube that ride on them are too. At that point you may expect a test of the intelliscope system valid. The manual for the XTi scopes say clearly that the goal of the system is to put an selected object w/in the field of the finder and my experience is that it does that well.
Many of us have these scopes. My 1st scope was/is an XT10i I bought 4th hand off ebay 'cause I didn't know better and it's been great. I've been all through it as many of us have. We can probably help you as you get this one up & running.
It’s not terrible, it wiggles in even the slightest breeze. I did find out last night, I had not checked the base the side board bolts. After tightening them down, it was better. Still to wobbly for my liking though. I did take the base apart and cleaned it up. I cleaned the bearings with alcohol and lubed them with soap. This was after I had already tried the push to. The seller did say it has never worked.
Worst case, Ken Fiscus, who is participating in this thread, might be able make you a plywood base to replace the stock base. He made one for me a few years ago, and he had some good suggestions here for repairing the stock base if that’s the problem. Do you know whether the shakiness you are seeing is the typical shakiness or worse than normal?
Regarding the Intelliscope feature, Orion is getting very hard nosed about not selling replacement parts or providing technical support to anyone other than the original owner, so hope you don’t need parts. If you do, sometimes you can find used parts on the Cloudy Nights classifieds. I sold some there a few years ago. I have had some luck getting Orion to sell me parts even though I wasn’t the original owner, it seems to be hit and miss. The good news is that you don’t need the DSCs to starhop.
I’m trying to save money right now. I do want to get a better base at some point. I want to get the wheel barrow handles for it too. Can’t afford it right now, have to go cheap.
Not sure what you mean by steady, whether it's loose or just shakes a lot. If the latter, I cannot stress enough how important it is to ensure your feet are in line with your altitube bearings (if you have altitude bearings instead of a lazy Susan configuration). Mine had the shakes - not steady - pretty bad. It made high power focusing difficult. After replacing the feet under the bearings, the improvement was very dramatic. Unbelievable how signifigant that small mod is. From shakes to rock steady in 15 minutes. Serious. I no longer feel the need for a 10:1 fine focus knob.
I’m not completely sure what you mean here, the feet are static and in the same position relative to the ground. When I turn the tube, the altitude bearing spin around the base where the feet are. Depending on where the tube is pointing, the altitude bearings may or may not be directly over the feet. This base has three feet so the altitude bearings are never both over a foot at the same time.
Sounds like your base has been dropped or damaged somehow - they shouldn't be that loose.
Not sure what gussets your looking at from hd - but I used 90 degree shelf brackets from hd - I think they come in black - do a good job of stiffening up the base (you can put them inside the base & the tube should just clear) - just remember to use something like a pan head steel self tapping screw - do not use wood screws !!! they break up the particle board & you will end up with a broken mess if you have to remove them - they don't hold near as well either. Also - I think your base might be 3/4" thick - so you will need 5/8" long screws - want to be careful of that too.
Can't help you with the goto - sorry.
I don’t think it’s been dropped, no signs of that I can see. I may try this. I didn’t think of shelf brackets. I was looking at corner gussets made from stamped steel. The shelf brackets seem like a better idea. How high from the bottom did you put the brackets? What size of bracket did you use? I’m thinking 6” would do it.
Last night before observing I did tighten the bolts holding the base to the sides and front board (didn’t tighten these the first time). That helped a bunch but still a little wobbly in a breeze
I have no idea what a normal amount of wobble is for these. I don’t have much experience with dobs. The dobs I’ve used seemed less wobbly that this one is.
As for the push to, I’ll update on that. I planning to do the test outlined in the manual. I’ve found it online and printed it.
Thanks for the replies, This is a work in progress as is most of my telescope gear.
