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!
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)
Sometimes the weather gods look on you kindly. A nice new Samyang 135mm turned up from that well known jungle supplier, I managed to assemble it to my Atik 428ex mono along with an Ha filter and got the spacing correct, and low and behold the skies stayed clear - all on the same day!
I am sure there is room for improvement with the processing but this is IC1396 processed in PI; STF applied with HT, and a little HDRM + LHE to try to tease out some detail.
Any help on improving the processing would be gratefully received - I really don't feel I get the best out of processing mono images.
By the way this is 12x300s + 10x600s combined with HDR process in PI; flats, no darks and a master bias.
Thank you for looking.
I have been thinking about having a go at widefield stuff for a while and wondered if anyone could recommend a used decent camera lens to look out for on ebay etc.
I would be using my QHY163C with it
I currently have an Altair 102 triplet and a megrez 72 (sold my 8"RC last year ...still keeping an eye ot for a C9.25 to replace it for planetary/luna etc) on a Mesu 200 mount
It would be used for wider stuff than I can get with the Megrez 72 ...say...the Heart and Sould Nebs in the same FOV.
Just thought it would be something to try if I can pick up an old camera lens for a resonable price ....is a zoom worth considering? ...camera resolution is quite high at 3.4 size pixels so is a fixed fl better then crop after etc.
Never done any AP with a camera lens so am total virgin with them....any thoughts/recommedations to put on the shortlist gratefully accepted.

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!
