Sun in HA 18-11-12 (The Tree and the Church)


Recommended Posts

Had a lovely imaging session on Suday morning in "runoffshed's" back garden with the PST and DMK41, this is my fourth outing with this equipment and the first time with a barlow added. The atmosphere was very steady with the only interuptions coming from Sybil the very curious cat and by John generously providing tea and bacon butty's, this sure beats messing around in the cold and dark :smiley:

The second image is an inverted close-up which to my eye looks like a distant church with a spire next to a tree on top of a hill, needless to say I'm very pleased with the results I'm getting from the little PST.

Yep, that is why quite a few of us do it I'm sure, though I for one don't get the tea and bacon butty's :rolleyes:

i have just purchased a PST and will definitely be using it for imaging, out of interest what were the capture details?

Hi Pete, it was taken with a standard PST mounted on my Astrotrac to follow the sun, the camera is a DMK41 and I used the 1.6x Barlow from my binoviewers screwed into the end of the nosepiece. I think the gain was about a third of the way up and the shutter speed was about 1/250th (I would normally use a much higher shutter speed but the seeing that day was remarkably steady) and the video file was about 1200 frames worth. Stacked in Autostakkert2, sharpened in Registax 6 and fiddled with in Photoshop, hope that helps and looking forward to seeing your images when we get to see the sun again.

Thanks for bumping the thread Bunnygod, I had missed these images.

Really good captures Melsky, I observed this 'tree' prominence visually and thought it was amazing, your caught it really well, so much detail!

Cheers

Lovely image indeed! Not seen the sun round here for a long time.

Pete- I don't know about the low profile nose and a guarantee of focus as I don't have either but I have been reading a lot about solar scopes recently and have read that individual PSTs vary and some do and some don't get focus with a shoulderless nose piece.

As Anthony says it won't guarantee it and I agree there is quite a lot of variance in the PST. I know mine won't reach focus even with the short nosepiece and I have to use a low power Barlow.

Hi,

It is not so much the length of the barrel, rather the shoulder that stops the body of the camera from touching the top of the eyepiece holder on the PST.

To get focus the body of the DMK must touch the top of the PST. Of course, a shorter barrel does help if you screw a Barlow lens in to it it gives a lower magnification.

      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!

      Hello
      I have been away from this forum from possibly July - I never find a lot of time to do anything these days, same to be able to relax reading and interacting Astronomy forums.
      I asked here a few ideas about making a solar scope or modifying whatever I had and I was recommended to also see Solar Chat Forums and I did.
      Thanks to solarchatforums I have been able to do something decent and here is what I have done so far - very slowly!
      1. I purchased a second hand PST and replaced its ITF with Maier one from the US and it finally had a clear image coming through + moved Etalon screw to third position - all the usual thing everybody does [after I researched it]!
      2. used a new SCT screw-on short focuser [used once or twice on a LX200 R Classic] and using Teflon tape I screwed the PST Etalon to the focuser and purchased a 2" adaptor to fit on Etalon.
      3. then used a Chinese 2" to 1.25 and modified the 2" side socket taking internal ring off and making 3x 120° threaded holes and 3x nylon thumb screws and used that as an adaptor to fit the original PST eyepiece holder - strangely enough at present this adaptor is also used as a tilter ... until I buy a proper camera tilter
      4. then fit the above eyepiece holder into the SCT focuser with 2" to 1.252 adaptor in it and screwed the whole Gold PST tube with Etalon in it and made a BETTER PST - see image

      5. I also initially tried a 2.2x DSLR camera Lens magnifier in front of PST and it decently works too - so PST will be fine for full solar disk mainly and without the 0.5 angstrom - not forcibly needed, I am probably around 0.7 as it is!
      6. more importantly, I decided to make my own 90mm solar scope using the above bits and pieces.
      7. with the help of Solar Chat Forums [great guys with a lot of knowledge, some are professional - i.e. they know the optics mathematical details - which helps] I purchased a cheap Bresser AR90/900
      8. the ONLY usable thing there ... is the main tube, a nice and thick tube - the rest is ALL plastic!!!
      I dismounted all parts and saw tube shorter ... a bit too much ! - I could have saved ~6cm really as I went with original ideas, but forgot I was using a different telescope from my initial thoughts - silly me!
      So, I added a 6cm extension - no problems there to reach the 20cm inward needed for the PST Etalon which has ~20cm FL
      9. initially I used a Tuna Fish 100g tin to adapt the SCT focuser onto my AR152 and fit Etalon inside the focuser to get near the 20cm needed- lets call it Quark unit - which it is really!
      It worked well, so I decided to add a second focuser to tune the Etalon ... getting back to AR90/900 ...
      10. I was trying to avoid overspending, I could not afford to spend too much - then I remembered I had a unused AR102SX which in my mind I guessed ... the focuser should over AR90/900 and it did!
      It just fits perfectly - then drilled three holes for the holding screws et-voila'
      11. I purchased a second hand 75mn Baader D-ERF and fit it INSIDE the AR90 tube at about 20cm inside from the front air-spaced doublet lenses, as there are the usual internal rings soldered in and just sit on it and I have about 70mm aperture  - i.e 70mm width from the D-ERF for photons to get through.
      At that ~20cm distance from front lenses the beam is still very large - probably about 60-65mm - there is no heat in between - no need for air-escaping holes
      12. when I have the time I will make a solar finder scope and fit it on the tube - not that is really needed - I usually use CDC to get there almost over The Sun [having an almost exact spot on the yard!] - then use my eye without eyepiece and look thourgh the PST eyepiece holder for solar shinging and centre the telescope over The Sun.
      Well, it works well after tuning Etalon focuser correctly and then focusing/tuning Etalon etc. - the usual.
      See some images - still learning imaging/processing and a lot more to learn about Solar ... a lot!
      I will probably need to get a Power-mate 2.5x when I can afford it!
       
       

      1st mod - without the original black box - it works so much better - better focusing and sharper viewing too.


      This is the AR90/900 shorten tube with AR102SX focuser and adaptors to test it normally
       

       
      This is complete with the Quark Unit on the right side
      Since this image there have been some changing - do not use the revelation adaptor any more and added a 6cm 2" extension.
       
      Here are some images:

      I acquired a second hand Coronado PST. The focus knob doesn't seem to have any effect on the image and, although it turns, it feels as if something inside the scope is "slipping".
      Is it worth opening up and taking a look to see the focus knob in action?
      Is there anywhere that services the PST without sending it outside the UK?
      Are there any nasty surprises if I open it up (springs, pressure points etc)?
