Hi ! Thanks for the video ! I am looking a part of my ETX90 RTA (right Tube adapter) which is broken and can't move the tube vertically anymore even the screw tight. Where could I find it ? Thank you again !

What RACI viewfinder is that? I haven't found one that can fit into the ETX's original mount.

@randallfosler 16 күн бұрын

That’s the Meade right angle finder that came with the ETX105 and ETX125 models. The ETX90 came with a straight through finder.

I am trying to update my autostar with my ETX90 using a very similar cable but am having trouble getting my computer to connect to the controller. When I plug the USB into the computer, it makes the connecting sound so it recognizes there is something in the USB port but no information is coming from the controller. do you have any advice on this matter?

Hello Nice video, with the wedge now you can track objects better? How much exposure time can you get with the base?

A cruel joke, giving a wedge plate for an etx. They can barely handle alt az mode. The optics are pretty killer though

@dw6528 3 ай бұрын

Thank you for doing this! I was contemplating adding a Celestron wedge to my Nexstar AZ for EAA However it becomes apparent that a camera on the back of the OTA would smash into the base for certain positions North facing objects would especially be affected. For example - it would be impossible to center the scope on Polaris. So it appears the wedge would only be usable for observing objects in the southern sky.

@randallfosler 3 ай бұрын

You would need to shift the OTA forward like I did by adding another dovetail. Or you would use a diagonal. I moved on from the wedge and returned it. I found a lightly used AVX mount that works much better for astrophotography.

@dw6528 3 ай бұрын

You don't need the guide camera while shooting the sun.. simply using cpwi or in your hand controller, set tracking mode to solar. Also, you'd be better off using that guide camera in your main scope instead of your phone and lucky image the sun..

I’m showing how to use a wedge and align the 6SE/8SE in EQ mode in this video. I’m not demonstrating how to use it on the sun. I’m demonstrating it during the day so you can see what I’m doing. I have an entirely different setup for solar observing the eclipse. See my other video for that. I use an AVX mount, guide scope, guide camera, and the PHD2 Solar version that tracks the sun perfectly for hours. Just using CPWI or the controller in solar tracking cannot keep the sun perfectly centered for hours for a long event like an eclipse.

Regardless, I tried the motor controls to point the scope at Jupiter but the controls did nothing. The controls work fine after powering off then back on tho. Any suggestions?

Try changing the motor speed to a lower speed (like 3) and move the arrows. Then switch it back to a higher speed like 7-9 and see if that helps. I’ve had mine not respond before and changing the speed back and forth seemed to wake it back up.

Very nice basic description of the autoalign procedure with a 6SE on a wedge. However, when i do this, the scope is way off when i choose the first star Sirius. if i then do move the scope to atually point at Sirius, the second star is also way off, and if I align the second star, it says the alignment failed. If I ignore the alignment and just pretend the 2 stars were actually aligned, it says the alignment succeeds - but of course its not actually aligned, and gotos fail. note that the mount is actually well polar-aligned, the arm of the scope is pointing to Polaris, and once I've got the index marks aligned, the scope is at 90 degrees to the arm, as you show in your video. I also accurately entered the date, time and lat/longitude. Last year I was successful in doing the autoalign procedure, although I found it finicky, but this year, with exactly the same equipment, it doesn't work. Any suggestions?

@randallfosler 9 ай бұрын

The things that can mess up your alignment are: - tripod not level - tripod / wedge not pointing north - wedge not set for your latitude - finderscope not aligned with main scope - telescope OTA not balanced - clutches slipping - backlash excessive and setting needs adjusting - weak power source (old batteries). I use a rechargeable Talentcell 12v battery. When centering an object, always finish using the up and right arrow keys. Put the object in the lower left of the eyepiece and then finish moving it up and to the right. This engages the motors for the direction they will use to track.

@viergarcia 8 ай бұрын

For a brief stint not too long ago, my 8SE (no wedge) was constantly failing to align. I use it with the wifi dongle and sky safari. I could not for the life of me figure out what was going on. Going through the hand control settings, I found the time zone and daylight savings settings were all of a sudden wrong. Who knows why. Corrected those two entries and everything’s been working well since. Sounds dumb but double check those on your hand controller.
