Same prom an hour apart with two different scopes


Recommended Posts

I shot the same prom twice with an hour between shots.  I used a 100mm f/9 for the left one and an 80mm f/7.5 for the second.

Thanks for the peek.

"Plus ça change plus c'est la même chose" or "More things change more they remain the same"--Fortunately for us!

Gorgeous images and it shows a lot of movement of these prominences.

Nice shots, noticeable changes between the two even in such a short time. How much difference in mag? Assuming first one x1.5 the second?

Exactly!  Nice observation.  Thanks!

Well, I feel suitably encouraged to work on an *80mm* Frankenscope now.
May not be the best of TIMES (solar minimum) but I have to give it a go! :p
Kudos for your sharing of interesting and *useful* comparative studies...

well that gives you plenty of time till next maximum to perfect the system 

see, there's always a silver lining :)

That 80mm shot on the right (above) was shot with the same scope you're using for your "Frankenscope".  You're gonna love it.  It's my favorite with the Quark.

      I'm still battling fairly heavy smoke from the wildfires west of my Las Vegas location.  Otherwise, seeing was 4/5.
      Thanks for the peek.

      Thanks for the peek.😀

      I am looking for a Daystar Quark Chromosphere. I am looking for a perfectly working unit without any degradation in optics. A few recently took images from the eyepiece are welcomed. The price is as low as possible (of course). Cosmetic is not a concern. Give me a message here or email me at <private contact details removed> (remove the {xxx}) to see the email address. I'll pay via paypal and accept shipping worldwide. Thanks for your attention.

      Sorry for the delay in posting, was just too knackered yesterday to do processing justice...
      Was out making the most of another clear night and grabbing colour data for M106. By 2am the sky was really clearing up, but Julie had decided that our "one walk a day" should be to hear the dawn chorus - so after less than three hours sleep, we were heading back outside just after 5am to be treated to a beautiful sight of moon and oncoming sunrise...

      Bird recording >Bird song.mp3

      We continued our walk along the footpath, beside the 'hedgerows' to get a better vantage point for sunrise...

       
      Whilst awaiting sunrise I had time to check GONG to see what was happening... more specifically the 'hedgerow prom' from the previous day...


      A Blue Tit announcing 'sunrise!'.... Blue Tit.mp3

      My intention had been to head home for porridge and bed, but decided that I really did need to have another go at some solar imaging beforehand... J was not overly amused 'burning the candle at both ends', etc!

      On the walk back home, the frost descended...


      All photos just with an old iPhone6

      back home, set the gear up and whilst the Quark was warming, so was the porridge!

      Although I'm fairly new to solar imaging, I can see why solar imagers get up nice and early to grab the best seeing. I could see the difference coming into OACapture from my old DMK41 camera just how 'relatively still' the recording was (a QuickTime screen recording below).

      Untitled.MOV   Refreshed today, here is my first go at processing.
      Captured at 7.59am 45 seconds @ 15FPS (max) best 100 frames taken from 676. TSA102s / Quark Chromo / 0.5x Reducer
      Processed with a 'bag' flat and dark frame in AS!2 and ImPPG via Wine on a MacBook Pro. Finished in PsCC2017

       

      Updated Gong image from time of recording. Definitely want to get better and perhaps source a better camera - I have a thread in Equipment if any Solar folks would care to offer advice...

      Just a very quick process from today’s play. Will update this thread at some stage - been burning the candle at both ends... Was out imaging last night ‘til 2, then the wife decided that it would be a good idea to go out at 5.15 this morning to take in the dawn chorus! After an extra 2hrs back in bed, decided to get out in the sun and enjoy some solar imaging today. Now, as I type this, I’m outside imaging again!
      So sorting the best files and processing will have to wait until tomorrow! I also took the opportunity to take test shots through the dial settings of my Quark to see if I can work out where best to position it to.
      Here’s a quick one, not as good as I’d hoped, but there’s always a chance another will be better!
      The best 60 of 679
