  1. Hi Here's M42 from earlier this month - Lodestar-C Share and enjoy Paul Image_M42_2016.2.10_21.30.55_00005.fit
  2. Hi Don Thanks for spotting that - now corrected! I've no experience of the Ultrastar RGGB devices, perhaps Paul81 will pipe in. CS Paul
  3. Hi Alan To open a saved FITs file the commands are: OSx (from the terminal): Colour: open -a /Applications/StarlightLive.app --args -load-image-cygm <File Name> Mono: open -a /Applications/StarlightLive.app --args -load-image <File Name> Windows (from directory with StarlightLive, open a command window): Colour: StarlightLive load-image-cygm <FILENAME> Mono: StarightLive load-image <FILENAME> Note: <FILENAME> must be the file name and full path to the file you want to load. Once loaded you can adjust the settings on the display processing tab to see what effects they have - note you cannot stack images this way. HTH Paul
  4. Hi If you're using windows you could have a look at Deep Sky Stacker - this will accept the FITS files and align and stack them for you: http://deepskystacker.free.fr/english/index.html There's plenty of tutorial on how to use Deep Sky Stacker and plenty on SGL that will offer help too. Once you have a stacked image them you can tweak the output using your favourite photo editor - however this is in the realms of astro photography so you may be better posting in the appropriate forum. HTH Paul
  5. Hi Dom Fantastic work - M1 looks amazing in the hubble pallete. Looking forward to seeing more! CS Paul
  6. Thanks for sharing - nice to see some moon video for a change. CS Paul
  7. Hi Martin To be honest, it's a bit of a pain, I followed the instructions here: http://astrometry.net/doc/readme.html#mac-os-x-using-homebrew Needs X-Code then just keep running Brewdoctor until all dependancies are fixed then download the index files. I've got a Python script that looks for the newest file in a directory then plate solves it, I tried using FITS format output from Starlight Live, however the CMYG matrix causes issues, so I have to save the current screen as a PNG then solve - if it finds a match will offer to sync your mount (assuming EQMAC with LX200 interface). Not pretty (I'm not a SW engineer and this was my first Python script!) but works for me. I've also looked at he version created by CloudMakers: http://www.cloudmakers.eu/xindi/ This works well with their Software suite but I have not been able to use it with Starlight Live as it only works with FITS images HTH Paul
  8. Hi Another great set of images - every time you post I look at what else I can try and capture!! The detail in M61 is astounding - what's the spacing from your F3.3 reducer to the Lodestar - it looks like you have it spot on. I might need to check the collimation on my C8 - I don't seem to be able to get anywhere near the resolution you get. Perhaps the low humidity which we hardly ever see here in the UK that helps - also difficult to believe your in a White/Red zone for LP too. Keep up the good work. Paul
  9. Hi A great start - I'd recommend no more than 30s exposure but to be honest it's amazing what you can pull out of 10 to 15s exposures too. Theres a lot of controls to play with - I find it useful to save my captures (FITS format) then when it's cloudy (or during the day!) you can load a file into StarlightLive and have a play with the different options including the ARCSIN and X^0.25 modes which can help bring out more detail in the images. HTH Paul
  10. Hi Paul Colour decoding looks much better and the defective pixel removal works well - I recognise that Test Card If you'd like more test data I'd be happy to provide FIT files from my Lodestar-C. CS Paul
  11. Hi Not posted for a while, but have managed to get out a few times this year with the C8 on the HEQ5 - I've been fiddling with the reducer spacing and think I've found a better distance - still not optimal and will have to experiment some more. (Working at F3.5 to F3.4 with the C8). Here's my selected catch with my Lodestar-C, mostly 30s exposures however M42 was 15s, some stacked using median others using mean stacking with info on the picture. Severe gradient in some images from general Bradford Sky Glow to the east of my location. During the cloudy nights, I've been playing with Astrometry.net and now have a working system which can calculate the actual centre of the image and sync the scope to these coordinates - off line with no internet connection. I can set up using EQMAC with a single star alignment (usually adjusting mount by loosening the RA and DEC clutches to get the target star in the centre of my finder) the I can retire to the warmth of my study and complete the alignment indoors. Using marks on my drive I can set up and be back in the warmth within 15 minutes, sometimes quicker - this is my idea of comfortable astronomy! CS Paul
