Mcphisto

Used my EQ3 for the first time.

Recommended Posts

I bought my Mak127 and eq3 in April. Due to the light summer nights, working shifts etc, it was only the other night I used it properly since I got it. This is how it went.

I set it up, levelling it first, pointing it north, its on the correct latitude, and I have a gps on my mount. Looked through the mounts ocular to check I was on the Polaris...off by a small bit so just tweaked the tripod to the left a little till it was in the crosshairs. Then setup on the handset. I did the two star alignment and all seemed good.

After looking around and getting used to the handset, I noticed that objects were not in the centre anymore, yet they were bang on in the finder scope. Any ideas?

Also I thought images in a MAK were the correct way up? But there weren't. Maybe I'm wrong but I'm sure that's what I was told.

But regardless, got to see a double star, the Ring Nebula and a few other bits n bobs. Not bad considering it was quite light polluted and to find stuff of interest in the part of the sky that was darkest, I used my iPhone app which totally ruined my vision.

Can't wait till next time :)

Did you make sure that the finder scope was aligned to your telescope? Even if you did when you started you may have knocked it a little bit.

I did yes. And it was ok for X amount of time. But like you say I must have knocked it, why else would it go out like that? Do you know if the image through the Mak is supposed to be inverted? I lined the scope up to a pylon on the mountain and it was upside down. I was under the impression it would be as normal.

If, as you say your targets were aligned on centre of your finder scope, but not in your main scope, then as has been suggested, there may be a miss alignment problem. Double check this during daylight by focusing on a distant tip of a TV aerial or church spire or whatever you have that is distinct, and bring this to the centre of both fields of view. If you ever come across a s/h cross hair ep like the Tal, this process is a lot easier and will give a high degree of accuracy. Well done on your first real session achievements :)

Sorry Mcphisto, I missed your response, got disturbed in the middle of typing, I think with reflectors your image is upside down and left to right :)

I missed this bit earlier :)

Were you using a star diagonal when you were doing this or a prism or was the eyepiece straight back in the back of the scope?

If you were using a star diagonal it should be correct side up, laterally (left-right) inverted. Without a star diagonal upside down but normal left-right.

I actually tried it both ways. But its not a problem, I was just curious. Thanks for the replies :)

      Hello everyone, I've got a question.
      I want to upgrade the visual back on the Mak 127. The standard back on the Mak is not pleasant to work with as seen in the image. I need to get rid of this plastic thing. I purchased a mak to sct adapter when I bought the scope, I never got around to doing anything until now as I've just acquired a Baader 2.25x barlow as shown in the image.
      Now, I've had a go of attaching the the Baader Barlow into the original plastic thing on the mak, it works .... but I'm not happy with the connection being made with the two locking screws, as there is still movement when the barlow, t-ring and Canon DSLR are all in the train.
      I've been having a look on FLO for some work around, does anyone have some input as to whether this will work.
      Mak to sct adapter-> Baader 2 inch to 1.25 reducer adapter->Baader 2.25x barlow + T ring & DSLR

      https://www.firstlightoptics.com/adapters/BaaderT2ext-1508153.html
      Any input or a better way of securing everything is greatly appreciated!😊




      Another option I've come across is this , Baader ClickLock 2"-1.25" Adapter  and Baader T2 Extension Tube to bring it to 40mm when attached to the mak to sct adapter. Anyone have any experience with this?

      Complete beginner question regarding using this mount.
      When I have tried to set up and align the mount , the goto targeting is off by many degrees.  Here's what I do - can someone tell me what I'm doing wrong!?
       
      With the power off:
      Align the tripod and mount to North and, with the clutches released, set the declination to my latitude (52deg 28' N). and the mount in the weights-down home position.
      Lock the clutches and fine tune the alignment on Polaris using the mechanical adjustments on the mount.
       
      Turn the power on:
      Set up the date, time and location, elevation etc. in the handset (noting the American Date format and Longitude first (set to W 1deg 48')
      DST = Yes
      Select 1 Star align
      Pick a star, I usually try Procyon or Betelguese depending on the time.
      The scope slews to vaguely the right direction but actually nowhere near.  It can take 2 or 3 minutes of manual slewing to centre the star in the eyepiece.  Finishing, of course, with an up and right movement.
      Finally, press Enter to complete the alignment ==> Alignment Successful says the handset optimistically.  
      Now from the object menu pick another target.  Try, say, Polaris which was where I started and ... nowhere near it.   It's the same regardless of the selected target.
       
      I have tried 2 star alignment and 3 star alignment, a factory reset before starting,  but nothing seems to work.   Once i'm lined up on a target the mount tracks nicely - it just won't go where I want it to!
      Not yet at my wits end but - Help!

      Hi everyone.
      A friend has an EQ3 Goto mount, I think it's the Sky-watcher one.    Currently, I know nothing about them, except that he's having issues getting it to work.  To the point that he's getting so frustrated with it he's seriously starting to thinking about throwing the mount away.
      He's described what's happening to me.    What he's saying is that the mount never points to the place where he's asked it to point.    He's saying that say the scope is supposed to point towards something in Orion, it'll end up pointing somewhere on the other side of the sky.     He's also said that it doesn't seem to want to track past a certain point in RA.
      I'd thought rather than simply jump in and try to help him out and get just as confused,  I was wondering if there's some check list of common EQ3 faults that I could work through to see if we can solve the issue.
       
      Once thing I do know is that he's running the mount from a dedicated tracer battery, so it maybe safe to assume that the power supply is good.   (althought it's something I'm going to double check as I don't want to miss anything)

      34 2-minute subs, no darks. Exif says 6c so the sensor was probably somewhere between -15 and -20C!
      Begging for a few more hours!
