Pleased With Last Night's Crop of DSOs (big files)

Recommended Posts

Last night was one of those unexpected clear nights; I had assumed the scattered cloud would spoil everything - in fact I lost ten or a dozen subs once or twice, but the mist was concentrated into the cloud and in between it was nice and clear and steady and despite the LP at home things went quite well.

Let's see what did we get?

First, 20 minutes on M15, just to wait while my real targets rose a bit higher. I like this because you can make out isolated blue and yellow stars in the gobular.

Next, the nebulosity around Gamma Cassiopeia, just 34 minutes as about ten subs were lost to cloud. Really a test as my last attempt on this one didn't show any nebulosity:

Sixty-nine minutes on the Wizard Nebula. It must be bright as it was clearly visible on each sub using the preview screen. I was going to do two hours but didn't allow for a branch 40-feet overhead:

One target I keep struggling with is M33, the Triangulum Galaxy. I got two hours of data and also used half an hour from three weeks ago. It didn't show up in the previews so the framing is a bit off:

Finally, the Plieades, 46 minutes before the sky started to lighten, plus about twenty from earlier in the month.

No doubt I will revisit these several times, but it was a much more productive session than my last dark sky attempt.

      Hi guys, it's my first post here, so Hello!
      My synscan goto upgrade started to act like in this video of mine SynScan GOTO Skipping after being disassembled for few weeks in the closet. There were no such problems before.
      When it slews at rates above x3 everything is fine and smooth but as soon as it starts tracking at x3, it skips steps or something like that.
      My setup is eq3-2 on alu and SW 150/750 with Canon 700D attached.
      Thanks in advance for any clues or ideas!

      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!
