  1. Hi What camera and mount do you have and do you already have a PC in your observatory and what software are you using? There will be a solution but it just depends on your setup. Paul
  2. Great capture and detail, especially with NGC4232 and neighbours - what exposure is this? Paul
  3. Hi Huw It's a start - welcome to EAA/Video Astronomy, there's no going back I use an F3.3 SCT reducer on my Skymax 102 with a MAK-> SCT adapter or a 1.25" x0.5 reducer - makes a huge difference to the exposures. Let us know how you get on. Paul
  4. Hi Chris I still have my SDC435 but have not used it in ages - I think I might get it out and try it alongside the lodestar. CS Paul
  5. Hi Paul The display does not come back when you modify the display settings - only when you return it to the original window where it was launched. Paul
  6. Hi Well it’s been almost 6 years since I joined as a member of this community and this is my 1000th post - not a lot in 6 years really but I hope that my contribution has helped, especially here in the Video Astronomy section. I still think of this section as my baby, although there are those who are now much more active than me. Back in 2011 there was no Video Astronomy section and at the time the Mods did not think that there was enough demand for one so Video Astronomy or Electronically Assisted Astronomy got lumped in with the Astro Photographers. So I set up a social group on the forum to enable us to discuss our small but growing branch of astronomy. Sometime later the forum underwent a software upgrade and social groups were no longer supported and rather than drop the small but active video astronomy social group we were given our on section on the forum albeit under the Science section. later we were moved to our own top level section and we have a much wider audience. The changes in Video Astronomy over the past 6 years have been incredible - I still have my SDC435 video camera which started it all for me, however I have upgraded to a Lodestar-C and am indebted to paul81 for his continued efforts on Starlight Live which has finally enabled my to achieve my goal of remote observation in the warmth of my study. Here’s to the next 1000 posts. Clear skies Paul
  7. Hi Paul Once again thank you for al the effort you put into SSL - each version gets better and better. I've noticed a minor issue when running on OSx - I use two monitor setup (Macbook Air & external monitor) - when I move SSL main window from one monitor to the other the image area goes black and does not refresh until I move it back to the original screen. Moving the Image Display window between monitors works OK. This is not a new bug - I have seen it in previous versions but forgot to mention it. Clear skies Paul
  8. Hi Starlight Live is great for the Starlight Xpress cameras, Lodestars in particular. Both this and Sharpcap run on a PC/Laptop so you'll need a HDMI output to a large screen. HTH Paul
  9. Hi Yes, that should work - I have used a similar one to capture the above images. Some people have experienced problems with the cheaper capture devices but mine worked OK. Paul
  10. Hi These cameras (SCB2000) work best at F4 and below, at maximum integration you are looking at about 10s exposure so some form of tracking will be necessary (AZ is fine). You can use cheap 1.25" focal reducers but need to make sure your scope has sufficient focus travel. The field of view is similar to a 6mm eyepiece so you may need some focal reduction depending upon which scope you use. HTH Paul
  11. Hi A few years back the SCB 2000 was the camera that many people used: http://www.ebay.co.uk/itm/SAMSUNG-SCB-2000PH-1-3-HIGH-RESOLUTION-DAY-NIGHT-CAMERA-600TVL-230V-AC-/152299740629?hash=item2375c59dd5:g:wwIAAOSwx2dYFnKb You'll also need a CS-1.25" adapter such as this: https://www.firstlightoptics.com/adapters/low-profile-125-nosepiece-c-threads.html You can improve the SCB 2000 sensitivity by removing the built in IR filter - however, you can use it with it in place. You'll also need a 12V power supply and some means of viewing the video - these cameras are Composite Video out only and can be viewed on a TV. You'll also need a video capture dongle if you want to view them on your lap-top. I use a small LCD monitor for laptop free viewing:- http://www.ebay.co.uk/itm/3-5-inch-HD-Color-TFT-LCD-Car-Rearview-Monitor-For-Camera-DVD-VCD-PAL-NTSC-G5C9-/172127998881?hash=item2813a0d3a1:g:N4AAAOSw54xUYc09 In either case you'll need a composite video cable - BNC to Phono cable: http://www.ebay.co.uk/itm/1M-Metre-Short-BNC-To-RCA-Phono-Video-CCTV-Coax-Cable-Lead-Plug-Adapter-Camera-/400778366660?hash=item5d50408ec4:g:l6UAAOSwPe1UIryC These can be obtained in various lengths and the benefit of composite video is that it is designed to be used with long cables. Here's a couple of images taken with my SDC435 which is the same as the SCB2000: Both taken with my C8 SCT using F3.3 reducer. The brightness down the left hand side is AMP glow and is common in these cameras when used at long exposure settings. HTH Paul
  12. Hi memoryman I've no experience of night vision cameras, although I've seen a few people experiment with it, there are security cameras such as the SBC2000/SDC435, which I have used, that have a night vision mode which can be used for EAA and can be used without a computer. However for the remote viewing experience you can share I'd still recommend the Lodestar X2 camera and Starlight Live software - in case you missed it, here's a video showing a typical nights viewing speeded up by x16 - C8 SCT with F3.3 reducer on HEQ5 mount Lodestar-C (not X2) and Starlight live running on a 2009 Macbook Pro from the warmth and comfort of my study with the scope on the drive outside: HTH Paul
  13. Hi Memoryman I'm biased - I spent my money on the lodestar and am very happy with it, however I've not experienced any of the other CCDs (only the SDC435 video camera). If I was spending my money again I'd get the latest Lodestar X2 mono (I have the colour lodestar) and go galaxy hunting and a little narrow band. Starlight live also allows you to do multi spectral captures live - adding each colour as you go. Just make sure you image at F4 or below and you won't be dissapointed! HTH Paul
  14. Hi Memoryman You will need to consider what software you will use for EAA/VA - a big part of the EAA experience is the ability to see the images on screen with minimal user manipulation and in particular, the ability to repeat the process automatically with each new capture. Starlight Live, Sharpcap and Atik Infinity software provide these features but I'm not sure what is available for the Moravian cameras. Nytecam produces great results using the standard Starlight Live capture software which shows you do not need dedicated EAA software but I think it can make a real difference to the viewing experience. I'm a big fan of the Starlight Express cameras and in particular the Lodestar range and Pauls Starlight Live software is constantly being developed adding new features all the time. HTH Paul
  15. Hi Jim Nice to see your set up - a permanent pier must be a real advantage. I have my scope and mount set up in the garage and move it out to marks on my drive so can be set up in about 15 mins also, however, I find that the polar alignment is never quite right and I cannot be bothered with drift alignment as I don't think it's necessary for EAA. (Quite a handful with the C8 on board!). I usually set up with the Macbook alongside the scope then move indoors with a 10m USB extension. I've recently been testing a 150' CAT-5 to USB extender off *-Bay with a 15m CAT-6 flexible cable, which seems to work quite well, although I have noticed that the download speed seems to have suffered (can still manage 1s exposures). I've yet to test this at low temperatures which is where my 10m USB cable used to fail. CS Paul
