I have an Ultrastar Color camera. I'm having difficulty with Starlight Live on my iMac. I have the latest version installed. When I load the software the camera is connected, but when I try to acquire an image, I never see anything. The bar at the left bottom of the screen indicates the image is being acquired, but the software image screen remains black no matter how I change the exposure settings. It works perfectly on my Windows 10 pc, but I need to use it on my iMac. Any suggestions?
Thanks so much,
After a bit of a hiatus, I was able to get out again and enjoy new moon/clear skies from a slightly less light-polluted viewing location. 🙂
For those who have seen my past posts, I'm still using StarLight Live 3.3 with a SX Trius 694 camera, now with SX filter wheel. I alternate between using an 8" SCT and various Borg refractors - these shots are with a 5" Borg, with exposures < 30 s. The combination works well, overall, and SLL controls the filter wheel which makes jumping between L,R,G,B and Halpha filters really easy and fun! The only major issues I have are that (on my Mac) SLL seems unable to run the Trius in anything other than 2x2 binning. I haven't been able to get a PC to test whether this is only a Mac related issue, though others have apparently been able to use this camera in all the various binning modes via SLL windows. I also have focus/framing problems if exposure time is set to 1s (camera drops out and SLL freezes up). To facilitate not having to refocus, everything was shot through either an L filter, R+G+B filters, or Halpha filter (all Astronomik 1.25", in a single filter wheel). It generally worked really well, but occasionally I would switch colour filters to do a composite and SLL would stop stacking and I've had to start my colour composite from the start again. But a fantastic feature of SLL!
Enjoy the shots - these (and others not posted) were all taken over a few hours time in the early morning. I love how much - and how quickly! - you can view with EAA!
I’ve recently got some shiny new kit, and last night was the first clear skies here when I had the opportunity to try it all out. This is not my first time observing, so I’m well prepared for unexpected issues, but it is my first time ccd imaging. There was lots of learning, including; cable management needs to be better, I (still) never have the right USB cable, and the focus tube needs some mechanical refining to address slippage. But the problem I’m not sure how to solve is one of focus.
I bought the SW Trius 814 kit (Trius 814, mini usb filter wheel with OAG, and Lodestar X2) and naively thought that perhaps if it was sold together it would all work together. And maybe it does, I’m not immune to stupidity
I could achieve focus with the 814 relatively easily, and even captured a test image and solved it in Ekos, all very heart warming. But I couldn’t then get focus with the Lodestar X2 (attached to the integrated OAG in the mini wheel) without pulling the focus tube out considerably further (approx. 50-80mm I didn’t measure). This obviously isn’t ideal. Am I missing something?
The setup is:
ED80 -> Field flattener -> filterwheel with OAG -> Trius 814 with the Lodestar attaches directly to the OAG.
All advice appreciated, and please don’t imagine that I won’t have missed something ‘obvious’
Starlight Light V3.1 is now available to download:
From the change log:
- Added 3x3 binning for progressive cameras only. 3x3 binning is not available for interlaced cameras.
- Added display for camera firmware version to the camera properties display.
- Modified Lanczos resampling algorithm to dampen sampling artefacts around bright objects (black halo around stars).
- Fixed Bug: Camera stability issues under OSX - updates to the libUSB library have improved stability for OSX 10.11 'El Capitan'. The application will now not crash if the camera unexpectedly disconnects.
- Fixed Bug: Date and time was not being stored in the FITS file when exporting to FITS.
- Fixed Bug: Detection of non-writable directories on Windows platforms.
- Fixed Bug: Signalling of critical or fatal application errors from non-UI threads causes a crash.
As always have fun and clear skies!
