I have the aforementioned telescope but not used it in several years. It's just been sat, quietly out of the way in a small cupboard (dry, dark, nothing amazing) but not stored in it's box as perhaps it could have been. Nonetheless, I went to take it out as a friend had asked me to take it to his for an evening's viewing pleasure. I tried the batteries I'd just bought (16xrechargables) but was unable to get any signs of life. Between myself and a friend who's somewhat more conversant with electricity than myself, we discovered so far that there's no signs anywhere of life from it - but we're not (as yet) sure whether it's a poor connection from the battery compartment or the switch. We do know the batteries are good.
Any advice on narrowing down causes, please?

I’ve been using my 8’ Edge HD on an Evolution mount for a couple of years now and I added a wedge to it a few months back. Using SkyPortal with StarSense I’ve never really had any major issues getting it aligned.
Last night I was setting up to photograph Mars and went through my normal procedure. StarSense took its images but, after confirming success with the third plate, instead of just winding up a bit and parking it proceeded to pitch the ota towards the north well below the horizon.
Fortunately nothing snagged. I skipped the ASPA and instructed it to goto Mars and was surprised to find it was spot on (better than usual actually).
Anyone any ideas why it took that nose dive? Thanks.
I'm aiming for the best possible field illumination for my Explore Scientific PN208 f/3.9 imaging newtonian. The scope is 5 years old now and while doing maintenance I wanted to do something about the design flaws as well.
With the current secondary holder design it's impossible to center the mirror beneath the focuser. My question is: is this really an issue when the entire primary is visible? I read about optimal field illumination when the secondary is centered, but this isn't achievable with this telescope.
I attached an image showing the (very bad aligned and already degrading) secondary at the moment. This is as far down as I can go, I would need to replace the holder screws with longer threads to go further but I don't know if it would make any difference for field illumination?
Thanks in advance,
Q. When using Star Sense, why does my telescope go all around the houses on some of its GOTOs? I'm sure I set 'Cordwrap' to 'OFF'??!! A. Because Star Sense reset it to 'On' after you did your alignment.By StarGazingSiouxsie
Now, I know that Cubble likes to keep fit. I try to keep all of my telescopes healthy and feed them only the best planets and DSOs.
But - why is that Cubble just LOVES to go all around the houses on some of his GOTOs?! Talk about taking the long way home!!! I could have sworn that I had 'Cordwrap' set to 'Off'.............
I have set Cubs up with a totally cordfree / wire free system and therefore find this going 340 degrees around to an object that is 10 degrees away incredibly annoying and time wasting.
Well, I think I may have found the answer today. Some of you may already know this but for those that don't, I hope it helps relieve some of your frustration.
What I disovered is that the Star Sense hand controller resets the Cordwrap setting (MENU>>>TELESCOPE>>>CORDWRAP) back to 'ON' each time a new alignment is completed. So, one can spend time seemingly making sure that it is set to 'OFF' (if that's the setting you want, of course) only to find that once you have completed an alignment, the hand controller defaults the Cordwrap setting back to 'ON'.
So, if you don't want or need Cordwrap set to 'ON', make sure you change the setting after completing each new alignment.
Hello, I am having a problem with a relatively expensive flat field eyepiece in a combination with a newtonian reflector. I am unable to achieve proper focus with that eyepiece because when I focus it on axis, the edges are blurry. When I focus it at the edge, the center field is out of focus. I don't want to mention the concrete type of this eyepiece because I received it with a spot on the bottom barrel, therefore I cannot be sure whether it has been dropped. This eyepiece has very good reviews on this forum. Optically it looks good and there is no rattle. My question is whether these flat field eyepieces are usable with newtonians as these telescopes doesn't generally suffer from the field curvature. Many thanks for help.
