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.
I need my garage back so am selling my excess mounts.
1. EQ5 motorised on both axis.
No tripod this was mounted ony pier. Tracks well.
£100 Collect only because of weight .
2. An older type Skywatcher AZ goto mount that came with my SkyMax 127. Good condition .
£100 Collect please but might be able to send if you arrange courier.
SOLDto Pitbull ...thanks
3. AZ GTi goto in excellent condition . Still have the box so can send at cost.
The pic shows it with a telescope on it which is not included.
Location just north of Newark on A1
Thanks for looking
mods VB please move
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!
I have been using my Skywatcher 8” Dobsonian for some time now, and decided I wanted a good refractor with an EQ mount as my next scope. I chose the Skywatcher Evostar Pro 80mm with an LX70 EQ5 mount. This seems to be a great scope to compliment my Dob, but I'm still getting used to the EQ mount! Found some good Youtube videos and am hoping for a clear night soon to really give it a workout! Any advice is appreciated!
I have an EQ5 telescope mount which i use for astrophotography. I have modified it with a motorised RA axis using a bipolar stepper motor - my thread for the build is here .
I want to expand the mount's tracking ability by motorising the DEC axis and using a guide scope/camera. I generally use the mount in fairly remote locations so would like to use a raspberry Pi for portability.
I understand that I'll need to use a Raspberry Pi Camera Module for the guide camera.
The capability I want is:
1. guide the mount along RA and DEC axes using a guide star as feedback
2. track the mount using the RA axis only, and if possible continuously take 20-30 second exposures on the guide camera (this functionality is optional, but would assist in polar alignment of the mount)
I don't want any GOTO capability. I am very new to RPi and need some help:
- do I need to write code for this, or is there existing programming available for what I want to do?
- is it possible to avoid the use of screens (in the field)? My preferred option would be to flick a switch to start and stop the guiding, with another switch for alignment mode (or something simple like this).
- do I need to use any particular stepper motors/drivers for raspberry Pi? I'm using a bipolar stepper motor running quarter steps, with an A4988 stepper driver
- is the RPi 3 Model B+ the unit I should buy?
