  1. I am sure there are loads of these polls but there seems so many available now I was wondering what, and why, people are using them. Poll is set to close end of August so it doesn't go on running forever. Thanks for participating Steve
  2. Hi guys, So on Tuesday night I spent the evening imaging the moon with my Celestron 9.25 SCT and DSLR as shown below and am happy with the images I collated (I only took images as I did intend to take capture video but I got carried away and time was getting on). I have approx 350 jpeg (and the equivalent in raw) images and have used the Microsoft image composite editor to stitch the frames together without editing them first etc but I wonder if I'm going the images an injustice? I'm not ready to pay for editing software as I know there is a lot of very good free downloads out there and I'm asking for recommendations. Should I be processing the frames before/after stitching and what software would you recommend? Please offer any advice you have. I will post the resulting image once I'm happy with the outcome Thanks in advance,
  3. Hi everyone I am a proud member of a team working on a multi-platform live stacking solution : ALS (Astro Live Stacker => https://als-app.org) It runs fine on PC (GNU/Linux and Windows 7 to 10), OSX and RaspBerry. Current stable version is very basic : Polling a folder to detect new images (any FITS or DSLR RAW) then align + stack (Mean or Sum) + autostrech + levels + RGB balance. ALS also has a built-in webserver so your pals at the astroclub can see the results, provided everyone is on the same network. We are working hard on new features like Dark subtraction + Hot pixel removal and are providing nightly builds for you guys to try it out. Check out https://als-app.org/nightlies/ Handling image capture directly inside ALS using INDI protocol is on our roadmap too. check out our Github repo to know more about it If you could give it a try and help us make ALS a fun & easy way to see and share all those wonders above our heads, that would be much appreciated ! Clear skies to all ! -- Fred
  4. Anybody know of a piece of software that could detect the change the occurred in an image? I'm doing a project to see if I can find an asteroid or comet without any prior knowledge of where said asteroid/comet is. I'm not really sure where to look for something like this, so any help would be appreciated. Also, I would like something that could run on Mac. But I'll run it on bootcamp if there is no other options. Thanks.
  5. Hi am posting this in case it helps anyone who has suffered the same problem as myself. In a nutshell: Own a Skywatcher Gti mount for some time now and used with some success, also purchased some time ago Skysafari and wanted to use both, with a problem much reported on the web and so much information out there that it can get a bit confusing and certainly in my case frustrating, after all just want stuff to work! After much experimenting and help from other postings this is what happens when you fire up the Gti. The mount generates its own wireless network and becomes the gateway, its IP address is always 192.168.4.1 you see this when making a connection with the Synscan app/program, its very similar to a normal router that serves you the Internet. Any device that then connects to this network then gets an assigned address one up from this, i.e. 192.168.4.2, .3, etc. However if you run the Safari app and go in to settings you will find it has also been allocated an address which is one up from the device you are using. In my case my Ipad was connected to the wireless network and had been given the address of 192.168.4.3. but when I checked the IP address in the settings page of SkySafari it was 192.168.4.4 ! If you accept this you get the error that the app cannot join the wireless network check your settings etc. If you now manually change that address to the same as the device running the Synscan app in my case .2 it should connect and work. However there is a caveat to this, I tried using an Iphone 4 and an old Ipad and they would not work together no matter what. I got the other error message that I had joined the network but the mount did not recognise the device type I had selected (Skywatcher Synscan Alt Az GoTo) and no amount of changing things would solve it. To get around this I used my trusty Win 7 laptop to run the Synscan program and things worked perfectly so it can be done don't give up! Sorry this is so long but I hope it helps someone out there. So to round off when you fire up the mount it becomes address no 1, any physical device gets the next address 2, any software running on the that device gets the next address 3. When you fire up SkySafari it must have the same address as the one that the SynScan app has got and this can e changed in SkySafari settings. None of this makes any sense to me as I thought software couldn't act in that way but there you are. I hope I have got this right feel free to contact me if things don't work Regards Bill

  7. I wasn't sure where to post this tip....it is probably of most use here.... Many of us with observatories or indoor Mission Control use Windows 10 Pro Remote Desktop to control a scope side computer running camera and scope control software from a second computer indoors. This works superbly at 1080p resolution. However, I have struggled for a year trying to perfect a wireless solution that works with 4K UHD cameras terminating in a 4K UHD display. Until now, whilst cat 6 cable does work fine, wireless even at 5Ghz 802.11ac has struggled with some lag and poor performance. I have spent a fortune upgrading wireless adapters and range extenders, but this isn't the issue! Here is a solution; 1. Seperate your dual band network into distinct 5Ghz and 2.4 Ghz channels. This is easy with (say) a BT Home Hub. If you don't do this, it can be a bit hit or miss whether your 5 Ghz wireless adapters connect to the right channel. You will now see TWO channels, one at 2.4 Ghz with a suffix like <hub name> and another at 5 Ghz named <hub name -5>. Connect your 5Ghz adapters to the latter. If your internal adapters are merely 2.4Ghz, you can disable them via Device Manager and plug in a USB version costing around £5. Note that at 5 Ghz wireless range might drop. If so, a Netgear EX8000 wireless extender is recommended as it employs 'mesh' technology. 2. ONLY if you have a fast network, and powerful CPUs and quality graphics card, try DISABLE 'RemoteFX compression' in RDP. This allows uncompressed screen data to flow across RDP. I have found this improves performance whether using 802.11ac wireless or cat 6 cable. What RemoteFX compression appears to do is limit effective RDP speeds to under 10Mbps (due to translation times). That is crazy if you have 433 Mbps adapters, and an 802.11ac network (or catv6 cable). Unleash the beast! Send across uncompressed data! The issue is not with speed or bandwidth, it is an artificially imposed limit in RDP. To do this type 'Edit Group Policy' in the Windows 10 Pro search box (doesn't work in Win 10 Home). You need to drill down through about five levels of Windows Configeration Folders, and Administration Templates and Remote Desktop Services/Host folders to find a utility named <Edit RemoteFX Compression>. In that, your options are <disable> compression or <enable> a compromise mode. If you don't know how to do this try Googling 'Disabling RemoteFX Compression' to find a lengthy Microsoft tutorial. Or visit https://docs.microsoft.com/en-us/windows-server/administration/performance-tuning/role/remote-desktop/session-hosts . I deliberately don't here state the quick route sequence to access this deeply embedded network utility command because you are delving deep into developer/administrator territory and do need to understand what you are doing and how to revert to your original RDP settings if your network can't handle these levels of uncompressed screen data. We don't want any novice attempting this on a cheap Compute Stick on an inadequate network! 3. When employing RDP from your computer indoors, select <WAN 10 Mbps> or <LAN 10 Mbps> as appropriate via <Options><Experience>. The default <auto-select my connectivity> often selects too low an option. The irony here is you can select this and still not enjoy faster speeds unless you have edited/disabled RemoteFX compression. I now have Atik Infinity plus CPWI software running in an end to end 4K UHD system terminating in a 4K UHD monitor. Over 802.11ac wireless it is now rock steady. Over cat 6 cable my system is now turbo powered. If you don't need RemoteFX Compression, don't let it restrict your network performance. It is evidently set to ensure it works on lowest common denominator networks. If you have a fast network/CPU, disable RemoteFX compression and finally release the beast of 4k UHD over RDP.
  8. I gave a demonstration/workshop at my local Astro Group* about a simple way of removing light pollution from an Astro Photo. The description I gave was deliberately for beginners, using a wide angle tripod shot photo and using one of the easiest packages to get to grips with (Paint.net). The attached pdf covers the basic technique. I'd appreciate any feedback on it. * The Mid Cheshire Astronomical Group - all welcome, we meet on the last Friday of the Month. LP MCAG.pdf
  9. Hi, What software or apps do you use to help you get around the night sky easier? Currently I might use starmap on my phone to help me when I'm out observing and I recently downloaded sterllarium, but I'm still getting to grips with it. Thanks, Shaan
  10. Hello! I was wondering if there was a preferred version of windows for imaging with dedicated cams? Have I read somewhere in SGL that many favor windows 7 over 10?.
  11. Hi, Thinking of trying to get my hands on something a little better than GIMP for my Astro Image Processing (something that supports 16 bit images). (and basically Adobe Photoshop is too expensive for me) I expect this has been discussed many times, but does anyone use Cyberlink PhotoDirector 9 (£47.99), or Serif Affinity Photo for Windows (£48.99) for their post DSS Image Processing? The reviews on the above programs are very good indeed on the internet (ie) Tech Radar I look forward to any recommendations or advice from those that might know please. Regards Steve
  12. Hi all While I've been largely locked under clouds for a couple of months, I thought I'd write some software that I've been meaning to get around to for a while. I use a standard LCD computer monitor for taking flats. I plug it in to my imaging laptop. I started off using a blank HTML page in a full-screen browser window to provide the uniform grey colour on the display but I needed to vary the brightness of the display for different filters. So, I wrote some software that does it. The software is called Second Monitor Lightbox and is available free of charge from my site (paw-print.com). If you use a CCD with filter wheel, it'll link to the filter wheel via the ASCOM driver so that, once you've set the perfect brightness for each filter, it will change brightness automatically as the filter changes. It also has a 'preset' mode for non-ASCOM set ups so that you can just re-call a pre-determined brightness to match a certain configuration (filter, binning, etc). There's a tutorial based around using SGP Pro on the site, so if you want to try it have a look through that. When you install it, Windows will warn you that it's from an Unknown Publisher. This is just because I don't pay Microsoft an annual fee for a developer's certificate. Just tell Windows to install it anyway - you may need to click 'More information' to get the option to go ahead. Let me know what you think. I hope some of you will find it useful. I know it saves me a load of hassle at the end of a long session trying to get the right brightness level to give decent flats for each filter. You can get it from here: http://paw-print.com Steve
  13. Hi Reinvigorated into imaging after attending a weekend SPA course at Preston Montford FSC centre, I've bought myself a Windows 10 laptop, but come up against a problem: I'm trying to install the drivers for the OpticStar DS335C ICE camera. I've got the latest drivers from OpticStar, but each time I try to install them, using the step-by-step instructions, I come up with a blue screen and the message: "stop code SYSTEM THREAD EXCEPTION NOT HANDLED What failed DS 335C64.sys" I've checked that I have administrator rights and that my laptop is indeed 64 bit. I've had no problems installing programs such as FireCapture (although version 6 didn't include the webcam option, so installed v.5 instead). Nebulosity which is on the same disk as the OpticStar camera loaded fine. Can anyone help, before I chuck the blasted laptop through the window and really make it crash!!!! (I should probably say that I'm normally a Mac user, so not used to such problems!)
  14. Hey Everyone, I bought a new laptop two days ago. Even though I do have the standard software like APT, PHD1,2, CdC, Stellarium, DSS, ASCOM, EQMOD etc. etc, Anyone have any other software in mind I could install? I'll admit that I kind of hoard them on the PC and not really use them.
  15. On the morning of October 14 the sky in Germany was clear and the seeing was between average and good. I wanted to test the new release of my MoonPanoramaMaker software, so I set up my telescope in the garden. In fully automatic mode the 30 videos for a high-res panorama were captured. Here is a "thumbnail picture" of the panorama: You find the panorama in full resolution here. Make sure to view the picture at 100% zoom. The inidividual video files were taken with an ASI120MM-S camera through a 685nm red filter and my C11 telescope. If you are interested in the technical details, you can see here two pictures of my setup. First the whole thing: And then a closeup of my laptop with all the necessary software running: Best regards, Rolf
  16. I have given a lot of thought to some of the software programs out there, like The Sky, Skytools etc. I suppose it is worth it if one is a serious observer.... but what about the casual observer. I find everything I need to know on free software like stellarium. What are your thoughts guys??
  17. Hi Using deepskystacker, I get double images after images are processed, any ideas to what is happening? Frank
  18. So I keep reading that sky safari is the best software out there, I use stellarium on my tablet and dso planner pro which is Ok, stellarium isn't a patch on the PC version but I rarely get the laptop out these days. Having missed the great Android sale last week is sky safari worth the expense £13.99 for plus and £37.49 for Pro, are sales a common thing? Is Pro worth over double the price of Plus? Help appreciated
  19. Hi everyone, I'm pleased to share a good news with you. Indeed, thanks to Partha Bagchi (https://www.partha.com/) we are now able to provide you an .app file for OS X users. This is a good improvement because no Homebrew or Xcode are needed anymore. Also !! the app is 10% faster for stacking. You can download the app here. Enjoy !!
  20. Hi all, Has anyone had any luck using APT along with PlateSolve. I had a quick go earlier in the year and at first thought it worked well as i happened to be on target. However, the next evening I was off target by quite some considerable distance and it still tried to tell me that the object was at the centre of the image - it wasn't! I'll try it again come the darker nights but just wondered if anyone had regularly had it working - just to make sure i'm not flogging a lemon!
  21. Hello, first time poster here :-) There is plenty of software out there for imaging on Windows but what about us fellos who are running Linux? I am looking at getting my first astrophotography rig and I'd like to keep it as cheap as possible. A new laptop could be within budget but I'd like to avoid if possible, the money could be spent on better things. I'd be using my DSLR, at least to start with. What are the options, capture & processing wise, if any?
  22. All, Just wanted to see what you guys thought about the Starry Night 7 software. It came with my scope and I thought it would be great. I considered getting the Pro Plus before I found out Celestron gives a copy of 7se with their scopes, but I'm not very impressed with the version that I have, so it makes me wonder if the pricey pro plus would be about the same. I have a Surface pro 4 tablet that I love but after hours of trying to getting the software to install, I gave up and blew the dust off of my old laptop because I knew it would have the proper drivers. SN7 installed and I've been playing around with the program (don't yet have the scope to pc cable for control) but honestly I'm not impressed. My surface has StarWalk 2 that I use as a guide when I'm out observing which I feel is decent (constant compass cal issues). Also, if you can't get microsoft .NET Framework 3.5 on your pc/tablet, know that starry night and the ASCOM control won't install. I would have had to reinstall windows 10 on the surface (among other things) to get the .NET 3.5 drivers to install, which I felt was just too much. I'm very computer literate and it doesn't scare me, but I knew that my 6 year old, falling apart laptop could run it because it has windows 7. It agitates me that the almost $1,000 Surface can't install the older 3.5 driver, but thats the first problem that I've had out of it. What's your thoughts on the software? Any others that you prefer? Also, what other chart & control software is out there? I know of a few, just want to see what the opinions are.
  23. I have a QHY9 mono CCD and a CFW2 wheel. I tried using nebulosity V3 to control the rig, but soon realized I needed a script to run the wheel. Would someone please know how to obtain one?
  24. I was out using Sharpcap with my asi174MM cooled cam , I ran my lights, rgb and darks . When I hit capture the cooler temp disappeared . I've never tried DS with Sharpcap before tonight "Planetary only" . I use maximDLv5 for capture and some processing , maxim tells me what the temp. is at all times . I've used 2 meade cameras and a Spc900nc with maxim but, only my Pictor 216xt had { tec} cooling . I finally got my Zwo to connect slow as all get out but, the cooler option won't activate { it's not highlighted}. Help !
