  1. Hi Richard, I used to use my EdgeHD 8” on an HEQ5 Pro Mount and I can confirm, with real world evidence, that it works. Are you going to use it for purely visual or do you intend to take photos with it too?
  2. Andrew has been a super kind soul with a very generous gesture that is going to be hugely appreciated by many many pupils. I will keep a thread updated with how the project develops, which hopefully will be useful for others thinking about starting radio meteor detection. Now cross everything for the build phase!!
  3. I would like to set up a radio system to detect meteors using GRAVES. There appear to be quite a few success stories of members doing this here, so I am looking to you all for your assistance in specifying the kit required. As I understand it, I need an antenna, connected to an RTL-SDR dongle, plugged in to a PC that is running SpectrumLab. I then tweak everything and the software will recognise the radio frequency 'hits' as meteors burn up in the atmosphere. Is this correct?! Next question is the killer one: which antenna and SDR dongle are recommended for this kind of system? I hope that you will be able to help. Many thanks, Gav.
  4. The Framing & Mosaic Wizard in SGPro is extremely useful. It helps you to frame up a target. You enter in the name of the object or its coordinates and it fetches a DSS image of that patch of sky. You then overlay a square (or squares, if planning a mosaic, with appropriate orientation and overlap attributes) for your set-up's field of view. Click 'yes please' and it creates a new target event in your sequence with the RA & Dec populated. Very quick and easy to use and a great way to start preparing acquisition of a new target; it makes the tricky job of planning out a mosaic ridiculously easy.
  5. I suppose the plan is that by having more income from this 'project' of theirs (they being Ken & Jared - who are two very nice guys, by the way!) will be able to spend more time on SGP and taking it forwards, rather than having to earn money from a day job and then try and support this every growing beast in the evening. The upgrade seems to work pretty easily, so if you have fears about the whole thing falling apart when you upgrade, it doesn't appear to be the case. Tonight looks clear, so I will be conducting a real world test... fingers crossed! I used to use APT many years ago and agree, Ivo, the developer is very responsive and has built a great piece of software. I had copious issues with APT crashing back then, I'm sure those issues are fixed now, but how does it compare to SGP, functionality wise? Is it as fully featured as SGP? Enjoy tonight's forecast clear skies, if you are lucky enough to be forecast clear skies, and I hope this new version of SGP doesn't generate a swell of bug reports tomorrow morning!
  6. Interesting responses, thank you all. Yes, it has come out of nowhere, hasn't it? Communication with their current customer base is evidently not a priority for the SGP developers! I have gone and paid the subscription for this year, in the hope that my 'premium support' access will get my various gripes dealt with sooner rather than later and that this is all being done as version 4 is about to be released, with amazing new functionality... go on, let me dream..! My problem is that I can't fault the software. It has been a relatively painful process getting it to work, but Ken and Jared have been very responsive to my problems and requests. For the money back then, it was great and I have enjoyed being part of the beta development process for them. I currently have a system that works and allows me to 'fire and forget'. I will have to look at NINA and EKOS, but I have to say that the idea of knocking down my current observatory 'house of cards' and the inevitable pain of trying to build a new one might just be too much for me and makes $59 seem worth paying!
  7. Ken and Jared at Sequence Generator Pro have just changed their payment model. The software has become a one off membership fee ($149) plus an annual subscription fee ($59 / year). Does this represent good value still? It has been my observatory and imaging control package of choice for about five years and was amazingly good value when it was a one off fee, plus very rare upgrade fees. I am wondering what the alternative software packages are that provide equally good (or better) control of everything? Please let me know what you use, how much it costs and how good it is! Thanks, Gav.
  8. Damn! Though I have had a quick search online and CS6 should work on Mojave... look at this: https://helpx.adobe.com/creative-cloud/kb/install-creative-suite-mac-os-sierra.html
  9. Progress is wonderful, but happens so quickly with all these digital devices that it doesn't take long to be left out of date! I have only just taken the plunge and upgraded my MacBook to Catalina and find that one of my scanners is no longer supported... doh! You should try updating your Mac to MacOS Mojave, which is OS 10.14. All your 32 bit apps will still work with that. Catalina is 10.15 and does require 64 bit apps, so avoid that until you are ready! Here's a link to find Mojave: https://support.apple.com/en-gb/HT210190 - scroll down to the download section and the app store link is there. Good luck.
  10. Thank you all for your kind comments. It is definitely an interesting target. I like @ollypenrice’s idea of ‘favourite galaxy’ - this one would certainly be on the list, but which would be top of my list? I’ll have to consider that one!
  11. You can load an integrated stack into APP through the ‘Other/Processed’ button at the very top of the 1) LOAD tab. Turn off Multi-Channel/Filter and Multi-Session Processing first. You can then apply the stretching etc in the right hand panel or got to 9) TOOLS and use them. Hope that gets you moving forwards.
  12. This is a very interesting topic! I love the focal length of an SCT, but they have a certain softness and are generally a bit of a pig to use for imaging. I have a Celestron EdgeHD 8" and almost love it...! If I had the cash, I think I would invest in an Esprit 150 and take the hit in focal length, but enjoy the vast increase in quality. If you do go for the SCT, be warned that really the only way to successfully guide it is with an OAG. I look forward to hearing what people reckon about the long focal length options available these days.
  13. Lockdown has been very productive for my observatory. I am slowly making my way through the multiple target data sets that I have acquired through the spring and summer. Here is my latest process: NGC 4725, the One-Armed Spiral Galaxy and it is pretty clear to see why it has that name! Most spiral galaxies have two or more arms, but unusually, NGC 4725 appears to have just one. It forms a ring around the core of the galaxy, giving rise to its alternative name, the Ringed Galaxy. Why just one arm or how it formed is a bit of a mystery! NGC 4725 lives about 41 million light years away in the constellation of Coma Berenices, the patch of sky found between Ursa Major, Leo, Boötes and Virgo. It stretches across about 140,000 light years, making it bigger than our own Milky Way, which is about 100,000 light years across. Data captured with Celestron EdgeHD 8" and QSI 683-WSG8 with 31mm Astrodon filters all on a Mesu 200. RGB = 10 x 600s each L = 27 x 1200s TOTAL = 14 hours Thanks for looking and I hope you like it! All thoughts and comments gratefully received. Clear skies and stay safe!
  14. Thank you @PaulM, @tomato and @Ronclarke. Yes, I did use ‘Calibrate Star Colour’ in APP, though with great caution. I selected my sample star areas as far as possible from the globular itself as the algorithm requires main sequence stars and the globular is full of anything but main sequence stars! Huge fan of APP, it has greatly sped up my processing workflow.
