When you do spot Polaris and know how to find it , I shine a laser torch through the polar scope or you could with a finder scope I guess to enable you to see where your set up is pointing , I then use sharpcap and my guide scope ..

Ok brill , I will definitely put one of these in the mount power train , fear of loosing a clear night and a motherboard for a little money well spent has got to be worth it .. thanks for the info 👍🏻🙏

Ah yes ok brill and thanks for your help 👍🏻 Much appreciated..

I’m guessing this would work ?

Can you send a pic of this 12v /5a buck converter please ..

Yes there was nothing loose at all when I opened her up , all looked hunky dory apart from the cooked bit ..

Well i use 3 a celestron lithium powetank pro , a celestron powertank 700ah and a car battery charging pack I think it’s 1700 ah .. I’d connected it to the lithium power tank fully charged I just use that on its own for the mount The others for dew heaters and cameras etc , I’m guessing it was a power surge after reading these messages , much appreciated btw .. or a faulty resistor or whatever , I will make sure I slightly drain the power supply before connecting it next time .. and look into something inline to restrict it to 12v , seems a bit ludicrous is a pretty new mount ..

Thanks I will have a look at doing that too ..

Ok will do , I’ll look into it further anyway make sure I’m getting the lacquer process right I don’t want to mess up the new board ..

Right that’s the info I was after the pop rating so to speak , I will look into a faster blowing fuse and I will take your advice and spray it with lacquer.. many thanks 🙏

Yes that’s what I meant , it was in he house stored in the dry .. I’d polar aligned without it turned on with sharpcap then connected the mount to the battery pack switched the on switch and pop .. same routine as always but without the cooking ..

Yup cost me a bit for a new board It will still be under warranty from rother valley optics but I don’t want to wait forever for a fix , l know nothing of the internals and boards etc aulthough I’ve got enough common sense to be able to replace it it’s pretty simple .. just hope it doesn’t happen again ..

It was totally dry at the start of the session no condensation at all but that residue you can see is quite possibly condensation from another night . I will certainly have to make sure it’s dry inside after a nights session in the future ..

Thanks folks , it’s not the Polarity as suggested above it’s always been connected the same , you can’t change the polarity, it’s quite possibly a power surge as suggested above but can’t understand why it wouldn’t blow the 5a fuse in the lighter socket ..

Hi all , some advice here please , last night I set up my mount EQ6 r pro , plugged it into my celestron lithium power tank as I always do and on switching the on button on the mount something went pop inside the mount and a burning smell followed , then all I got was a red flashing power light and nothing else , obviously well not obviously but I think there was a power surge and it fried the motherboard , I’ve already ordered a new motherboard but what steps could I take to make sure this doesn’t happen again , surely the fuse in the power supply (12v car lighter socket type) should have blown before frying the motherboard , or should I use a lower rated fuse .. or something else .. ? I’ll be worried I’m going to fry it every time I turn it on now .. any help appreciated , thanks 🙏
