Polaralign / EQ5 goto w/3.32 Firmware

Recommended Posts

I've just recently flashed to the new EQ 3.32 handset firmware.

However, there are still a few things i'm still unsure of - big shock there ;)

When I set-up each time - i cant have a permanent fixture unfortunately - I often get confused as to how exactly I should go about aligning the mount. :huh::confused::eek:

I have heard people say to set the lat for my area (ie 52) , and occasionally its been referred to as a seperate step to getting polaris in the polarscope. This is likely my mistake, but, to my way of thinking, wouldn't getting polaris in the crosshairs of the pol-scope do the same thing as setting my lattitude correctly?

The goal being in both cases to get accurately polar-aligned.?

Which brings me to the other query. After levelling mount and aiming 'N' leg North, then roughly sighting polaris in the P/scope - how would I adjust things to get polaris at the right 'hour' in the reticule? So far I use a combination of adjusting the lat/az bolts and nudging the actual tripod a bit by grabbing the rear two legs while looking through p/scope.

This seems a tad sloppy to me, as the two different ways of adjusting the pole star's position in the reticule might leave room for error, or rather more error than necessary.

Ive not yet tried the new firmware - could anyone be nice and explain the steps so an idiot - thats me btw - can follow them? ;)

Skywatcher actually have quite a good instruction manual for this update on their site, highly recommended, but after a few reads I still need a little clarification.

Possibly not question of the month - badly worded and rambling - but anyone have any advice as to the correct way to fine tune the polaralignment ie nudging tripod legs versus adjusting the mounts alt/az bolts?

Just a wee bit hazy on the exact method.

Pweese?

There should be 2 thumb wheels above the north leg to adjust in az similar to how you adjust in alt.

Ah, oops, my bad. I knew the way i'd phrased the question was strange, sorry!

I'm actually polaraligning ok, and am mainly trying to fine tune the process. As i'm getting 30 to 40 seconds exposure before trails start, its time to make the effort to align properly.

But i'm not sure if the way i'm going about it is wrong or less accurate. - after getting polaris in the cross hairs of Plr-scpe, and say polaris should be at 12,0clock (is that the top? but anyway..) should I resist the temptation to nudge the tripod legs as i'm looking through the polr/scope? and only try using the alt/az bolts? , as the polrscope is v crude and the procedure should be exact - my biggest problem being the set-up is not permanent - so i'm hoping to learn a lot more about the aspects i'm a bit vague on.

Hopefully anyone that has to do it from scratch each time will maybe have noticed certain do's and dont's or that one way works better than another. (?)

(Also, with the new firmware 3.32 - the polar alignment feature is presumably best done a particular way.)

Really sorry for the confusion, often I have trouble being conscise and tend to babble...... :p

Thank u 4 replying anyway :)

That's not bad for non permanent unguided.

I'm not understanding a) whether you are polar aligning on on the crosshairs or the tiny circle and B) why you would move the tripod rather than use the screws that are more accurate and designed for teh procedure.

(Also, with the new firmware 3.32 - the polar alignment feature is presumably best done a particular way.)

Opinions vary on how well the new function works. I myself found it less accurate than the polar scope method.

The best method I've found so far is the Ascom utility, but i'm trying to get AstroTortilla to work so i can try the plate-solve method.

Many thanks dude,

Appreciate the specific suggestions, its what i need - advice from experience, thank u. :)

Yeah, i'm starting to try getting polaris in the right area of the reticule by using the HA:polaris clock on the handset, but if I get it wrong its going to be -further- out than just centering it, you know, if its the opposite side through the cross to the other side then my PA is worse than roughly central...- if that makes sense/?

So, to get polaris centered whilst looking through polarscope sometimes i grab the back legs to locate polaris initially, and once centered I often give the back legs a nudge to save wear and tear on those soft alt-az bolts - i'm getting the better ones v soon - but due to the various angles involved in aligning the polr-scpe using the bolts might not be a wise move, hence asking the strange questions.

Thank you for ur input - very grateful. :)

you can't go wrong with where the little position circle should be if you use something like the free polar finder software.. (http://www.polarfinder.com)

OK. Thats reassuringly simple, though its sometimes confusing when the RA is rotated to where the reticle overlay of cassiopiea and ursamajor line up - is it an accurate estimation or should I go by the hour-angle and place polaris on the circle regardless of whether that little bubble matches up? ie using polarfinder to put polaris on the larger circle without having to get the bubble to that exact position as well?

Again, both thank u 4 the advice and apologies for the rambling ;~)

Edit: your astrobin jupiter is very nice, btw

I find that I can get about 2 minutes unguided by just putting the little bubble as near to where the software shows me as I can. I don't use the setting circles at all as i find they slip too easily.

Thanks for you comment.

2mins is great.

I think, but not sure, that my mount is not allowing me to improve the exp. times regardless of what I do, but alot of folks have managed at least a couple of mins. I cant complain really untill i've tried to set-up properly rather than roughing it, so basically until my budget allows the mount upgrade there is a challenge for me to tackle :p

I ordered the revelation 5x barlow, off subject here, how do you think it'll perform on my 200p?

Again, many thanks.

You'll need either extremely good conditions or a camera with high frame rates to get good results, but you may be lucky. I use a 2.5x and a 2x or 1.5x barlows stacked and sometimes with upto 120mm of extension tubes so not too far off 5x. I think the jupiter you referred to was with 2.5+1.5 on my 200p.

Thats the one, yes - absolutely brilliant. You use extensions to increase power? Didn't think of that, good plan. :)

Thanks for the help.

      Hi all, looking for some help please! 🙏 I have a wedge for my 8SE and when using EQ North to align it, it says it is slewing to Vega but ends up all the way over at Polaris!?  Any ideas? 🤞🏻 Thanks in advance! 😊
       
      I have updated the firmware, Mount is pointing at north, have inputted my latitude and longitude, I have tried picking the nearest city too and nothing seems to work! 😟

      Hello guys,
      I recently got into astronomy so I bought my first telescope. I've read through several articles and the recommendation for a beginner's telescope (value/price) was Celestron Astromaster 130EQ-MD. I bought this from someone who was not really using it and it is in a very good condition. Prior to actually purchasing this, I've watched countless videos on how the telescope works, what needs to be done - latitude, RA/DEC alignment, polar alignment, etc..
      After reading through all available manuals and videos, I finally brought it home from the seller (they've had it for around 5 years but it wasn't used much). After setting up the tripod, mounting the telescope and familiarising myself with all the different knobs, I pointed the mount/telescope towards north. The first thing I had to do was setting up the latitude. Since I am based in London, the latitude is around 52 degrees. Afterwards, I had to align the declination axis so the telescope can be balanced. As I understand it, you should be able to move it to any position on the axis and it should stay in that position. If the front or rear was heavier, I would either pushing or pulling the telescope after unlocking the brackets holding it together. This is where the issues began, I could balance the telescope so it doesn't move while in the horizontal position, however, when pointing it towards north, it would exclusively lean towards one direction - to the left. If the telescope was pointing to north, north-east or east, it would pull towards the west all the time. It is probably easier to show it in the video. I've spent three days trying to balance the telescope by using different methods and it just would not work. 
      I've also tried balancing the RA axis first. This could be somehow done, but the declination axis would still pull the telescope to the left.
      It is extremely frustrating as I don't know what could be causing this. Balancing the telescope should be relatively easy from what I have heard - either push it or pull it depending on where the weight is. However, I have been really struggling to get it set-up.
      I would be thankful for any suggestions and please feel free to ask any questions so I can help with finding out what is wrong.
       
      Thank you.

      Can anyone help? I'm pretty much a novice at this astronomy stuff but loving the steep learning curve. I started by using camera lenses modified to use an eyepiece but after much debate, deliberation and saving up, I have finally bought my first proper telescope. Unfortunately I now have a problem.
      Last year I bought a second hand Synscan EQ5 mount which has worked perfectly each time I have used it. I  used it about a month ago for the first time with the new scope (last time we had a clear sky). Everything worked as it should. At 2 am I parked the scope, dismantled everything and put it away. Nothing was dropped, snagged or got wet.
      The forecast said we might get a clear sky last night. Anticipating this I got the mount on the bench, stripped, cleaned, polished and greased the DEC axis plain bearings (hoping this might help with guiding). When finished I connected the motor controller and handset and switched on. I was greeted with the following messages: INITIALISING then CAUTION BOTH AXES NO RESPONSE. If I press enter and carry on through the menus, then everything appears to be as it should except no motors run. I have tried everything I can think of and would be very grateful of advise or suggestions. These are things I have tried, so far:
      Factory reset
      Different power supply. I have been using a motorbike battery which is giving 13.5V constantly when I switch on. I have tried two other batteries with a 2A charger connected.
      Continuity tested the cables from the plugs that go onto the motherboard of the controller all the way to the motors.
      I made up the  RJ45 and RJ12 diagnostic cables suggested in the manual and the handset appears to be ok.
      Removed the motors from the mount to make sure that they turn freely.
      Replaced the RJ45 cable from the handset to the controller.
      Examined the motherboard for dry joints and damaged components.
      Assembled everything in the tripod to make sure that the earthing tab on the controller made no difference.
      I now feel that the problem is the controller motherboard but logic tells me that it was the mount I disassembled, so the fault should lie there. Is there anyone who has had the same problem or who has the same system that could help me diagnose the problem. I'm in North Shropshire but happy to travel to anyone who could help. Unfortunately I don't know anyone with the same mount.

      I own a polarscope from FLO for a couple of months now, however I have never been able to get a correct polar alignment.
      When I screw in the polarscope in the mount completely then the 3 angle is at the top (see picture). 
      However with this polaris keeps moving out of the circle when I polar align it. (Polar alignment seems not to work)
      When I loosen it I can get the reticule to 0, however the polarscope is very loosely in the mount.
      How to best get the polarscope correctly into the mount and get an accurate polar alignment.
