  1. Past hour
  2. nice shot rusty, watch out you will become quarkers mate . im having a day off today, im a bit under the weather. well done. charl.
  3. Hi all. If like me you've been clouded out of it for weeks on end, a bit of relief might come in the form of data to play with. This is my Dusty Taurus from November 2018. 6.5 hrs in 150 second subs with my now sold (what was i thinking) Tak Epsilon 130 and an Asi 071. A feint molecular cloud 450 light years from earth which includes Cederblad 30 and LBN 782 This was my effort https://www.dropbox.com/s/q2z3r90478lvyhl/St-avg-23700.0s-WC_1_3.0_none-x_1.0_MNC-NS-full-qua-add-sc_BWMV_nor-AA-RL-noMBB-lpc-cbg.fits?dl=0 Look forward to see what you can do with the data. Richard.
  4. It should be possible to settle part of this argument by using optical formulae to calculate the shift of focus caused by the moon being 240,000 miles away rather than at infinity. The focus may also shift with time as the scope cools down.
  5. OK so I've hit the dreaded capitalisation issue again! It's CASE SENSITIVE! haha, so it's /dev/ttyUSB1 I'm now getting a different error, it's just saying failed to capture rather than failed to open serial port...
  6. Have you had a look at things like Stellarmate and Astroberry? They are both dedicated OS builds of Ubuntu for Astrophotography. They come with all the drivers and bits of software already installed. Then it's just a case of adding your equipment and banging your head against the wall for a few hours while you try to learn new software and then you're golden haha I'm currently trying to move over to Astroberry running on a raspberry pi for everything but my Nikon D5000 doesn't seem to be liking it properly yet. I think the software needs to take the camera out for a few more meals before they will connect properly
  7. Demonperformer - I like it! Definitely one up on me shining a torch in a neighbours face! Pehaps invite the coucillors, and environmental health, and lighting dept (first time at least) at a more reasonable hour. If they don't attend, or have the courtesy to respond, then step up the time/fequency of calls. When my messages are ignored without good reason, I double up on the reminders - every time. 1, 2, 4, 8, 16 - the messages do get a response eventually!
  8. Hi Carole! Not sure if this is my poor explanation or poor understanding! What I mean is if I rotate the camera in the scope, the position of the notch rotates on the finished image. So instead of being at 10 oclock its at 2 oclock. If the camera were the problem, the notch would be always in the same place on the image, no?
  9. Are you running this through a usb/usb3 hub. I found mine did this but was definitely better when running it off its own dedicated usb lead to usb2 port.
  10. So that's what was missing? I thought I was one Quark short of a set. Thanks.
  11. Great work! It's always fun when you first get something working no matter how small it is! You current process is pretty similar to mine by the sounds of it although I don't use stellarium on my imaging machine as it would use up too much processing power & RAM (I have a weak imaging PC). I don't generally do much of a polar alignment, just a rough one since using plate solving. Turn everything on, focus the imaging camera (guide cam stays in the scope at all times so its always focused), connect everything in APT, auto plate solve, slew to target, start guiding, start imaging, drink beer haha
  12. Instead of having everything bolted together as a monolithic block, have you considered using heat pipes (https://en.wikipedia.org/wiki/Heat_pipe) to conduct the heat to different areas to meet you needs ?
  13. Hi Steve Your right! Although to some people I didn't get far last night for me It was leaps and bounds When I saw that picture of Vega, although I just found out how to alter the histogram to get the proper darkness I was shocked an amazed on the quality of my first 10 second image. The important part is I got everything working as it should but still need to learn the softwares back to front and continue learning in a never ending process I enjoy learning new things and love the challenge on working most things out myself. I have shed loads of questions but try and focus only on my next step to try and not complex things too much. By being able to goto which part of the sky and focus a target I want, will let me start capturing and introduce the next step. I am not looking forward to post processing so much but thats another learning curve. I will have to deal with it when I have some decent data to work with
  14. I got this little piece of the Moon in the mail today, and a few other meteorite bits too Here is the official classification on this one (North West Africa 8277) for those interested: https://www.lpi.usra.edu/meteor/metbull.php?code=59500
  15. Some round black and orange things. Not bad for £15.99 delivered for a brand new set.
  16. Hi All, My ED80 had the old single speed focuser and I would like to be able to fit the dual speed version to it. Would anyone know if this would be a direct swap over or is the DS SW focuser different and the whole part needs changing. I have been looking for ages for either a unwanted one or one that has been damaged but usable but so far fallen short. I do not want to use an alternative as they all seem to be missing the thread on the rear of the focus tube so I am not able to directly screw on my FF. cheers,
  17. It says to me it's the camera not the scope if the notch rotates as the camera rotates. When I first saw it I thought you were using a reflector and it was the focusser sticking into the star (as happened to mine until I chopped a bit off the end of the focusser. Not sure what to suggest with a refractor except my first line. Carole
  18. By the way isn't it a great feeling when things do go right on a session. Even if you do not get the data you really wanted just the fact you learnt how to do something and it worked is a great boost Steve
  19. Nice. Have you tried Imppg for sharpening yet?
  20. I caught up with Pallas last night. Here is a single frame from a short avi captured with a Watec 910HX/RC mono camera attached to a Celestron 9.25. Pallas is the brightest object near the centre of the image.
  21. As I said I am pretty new to imaging and learning but to be honest I had a few issues with Stellarium at times and struggled to get good allignment till I started using APT (a brilliant piece of software - I paid the small fee as well worth it). Now I have stellarium open but I do not use to move the scope as such, I really just use it to see what is in view and to pick a target that I then know will get at least a couple of hours imaging before it is out of sight. I do double click on it in Stellarium but then back to APT click on the object button, whilst holding down the shift key, and the position of the object will be transfered to APT so you can slew directly to that object in APT using the GoTo key. Take a test shot, can be short just enough to get the stars not necessarily the DSO, in platesolve click on "<<Scope Pos" to transfer mount position so it can solve quicker, then click "Solve", when succesful click "Sync" and you will see the position in stellarium move a little. Then if you want the exact position just double click on object in stellarium again, in APT click on the object button again, whilst holding down the shift key, then click GoTo. Like I say that is my current method, Others may correct me with a better or quicker method. So no need to have scope connected in Stellarium at all in fact I do not open Stellarium Scope just Stellarium (ANGLE mode). Whether this is correct or not I am not sure so do not take this as a done thing Steve
  22. Serves me right for starting AP whilst living near the city centre.! I get better results the clearer the sky. Platesolving makes life easier and gives me more time for actual imaging. Louise
  23. Hey Carl, I set the dish up and tried an observation. This is my block diagram (electronics chain): Single linear polarization feed -> LNA -> LNA2 (in-line amp) -> 3m LMR-400 low-loss cable -> Bias Tee -> 1420 MHz Bandpass Filter -> RTL-SDR V3 -> 60cm USB extension cable -> Computer I observed for about 6 or 7 hours, with a not-so-proper-but-still-OK averaging (it takes about 5 minutes to go from the "noisy" spectrum curve to the averaged smooth spectrum curve, so you can kind of say that it averages over ~5 minutes). I uploaded the Observation on YouTube (I wrote a quick script that takes screenshots every minute for 6 hours and sticked the images together). I also recorded (unaveraged) Waterfall plots, in case I got a very high SNR and things were also visible in the Waterfall plot without averaging. Any idea why there is no (apparent) detection? I'll admit I was quite a bit optimistic this time with a 1.5m dish pointing to zenith, but I don't think I got anything... I have three suspicions: 1) The feed's monopole is misaligned - I set it perpendicular (90deg) to the grid bars, expecting ~100% efficiency (since the bars will act as a polarization filter, I turned it so I got the most out of what's reflected). If I've done this wrong I'm probably receiving nearly 0% of the incident waves. 2) The software can't extract the emission from noise without averaging for longer (not sure how long you've averaged for to get your results but I didn't expect I'd need over 5 minutes of integration time for a reasonably high-SNR detection). Perhaps I'll need to work with different software or write another GNU Radio flowgraph. 3) The primary LNA is not getting any power (I don't think that's the case cause my in-line is having a LED lit up, so it's definitely getting power - the question is if it forwards the DC voltage to the primary LNA, but I don't think that's the problem - wish all LNAs had an LED on them though, it'd be super helpful for knowing if they get power or not). Here is the YouTube video of the Observation: [to be edited once upload is complete] A few pictures of the setup:
  24. There were no details about when the first one is going to be, but they did say the timing was suspiciously good for the opening of the 2020 Olympics. They see supposed to be a display that can be enjoyed (relative term) over a distance of 200 miles. They did not say if that was radius or diameter!
  25. Thank you Steve! I only see one problem when SGP and PHD2 are running you can not lock on to the com port with Stellarium as its being used and by pressing connected in Stellarium it does nothing. If i shut down SGP then it will connect. So I guess i align it in Stellarium first with APT?
