  1. Further to my efforts to spruce things up a bit in the observatory with the addition of some polished mineral spheres to represent the planets* - I've now added some pop art posters I bought from the Astronomy Now! magazine shop :-) I liked them so much I bought a set for the TV room in the house too David *the spheres have now been moved up on to the disk/shelf of the roof beneath each of the planetary symbols - took me a while to figure out that that was the best place for them har har!
  2. A Broom on a dodgy night

    Conditions were lousy near me last night too but I still attempted some luminance on NGC 6888 - it's good practice even if the subs will probably not pass the QA check :-) Your effort above is really very good and hopefully you'll be able to add to in the coming darker months. David
  3. I was lucky enough to get some clear skies on the 10th of August to see if the spacing has been corrected. This is 19x5min in Ha It's better - but not very good - however I think it will be close enough for my expectations :-)
  4. I've found it useful to keep the handset connected for those times I want to observe rather than image - so that I can control the movement of the telescope while standing at the eyepiece - I just have the hand controller attached to the base of the mount with the usb running to the control hub so its out of the way most of the time. As for the Celestron driver - it was necessary when I started using EQMod years ago but may not be now.
  5. When I use EQMod I use the Celestron driver - and you need to turn on PC Direct Mode under utilities The Skywatcher driver doesn't appear to work with PC Direct Mode - certainly doesn't with SN7 - but I may try it running EQMod later out of interest Hope that is of use David
  6. I've searched a few forums looking for help on this subject and wasn't able to find anything - so I'm posting here in the hope that it helps others. With the help of the Simulation Ciriculum Corp I've been able to connect Starry Night Pro 7 to my NEQ6 SynScan mount. I believe the process will be the same for earlier versions of SN7 that support telescope control. Here's how I did it First - you'll need to ensure you have all the required ASCOM drivers and ASCOM itself installed before attempting to connect to your the mount (not discussed in detail here). 1. Download the SkyWatcher driver here: http://ascom-standards.org/Downloads/ScopeDrivers.htm#synta or here http://download.ascom-standards.org/drivers/SkyWatcher(6.0.6262)Setup.exe 2. Connect your mount to your laptop via the SynScan hand controller (detailed process not discussed here) and go to Control Panel to see which port it's connected to - make a note of the number. NOTE: Do NOT put your hand controller into "PC Direct Mode" (as you would with EQMod etc.) - this will prevent connection to SN7 3. Search for "Telescope Control" in Starry Night Pro 7 > under Setup click Congifure > select the SkyWatcher driver from the drop down list (ddl) > click Properties > select the port number noted above > complete the remaining fields in the properties window and click OK. 4. Finally, click Connect The big thing to remember here is to NOT put the hand controller into "PC Direct Mode" I'm still testing this configuration, for instance, I need to update my hand controller to ensure I get full functionality out of SN7 as the SkyWatcher driver is built for the latest version of SynScan. Hope that helps, and thanks to the Simulation Ciriculum Corp. team for their help with this. David
  7. Excellent! Thanks - I just downloaded the latest PI update
  8. Thanks for the info about Oiii - I didn't know there would be a difference at this wave length. David
  9. UPDATE - I actually had the spacer I needed last night (to replace the nose piece adaptor) ! Gawd! What's worse is that I was searching this forum for guidance and came upon MY OWN POST - describing how I solved the spacing issue with it !!! Lol! It has been THAT LONG since I imaged with the 115mm that I'd forgotten all of this :-(
  10. Just had a look at your NGC 6888 - that's now my benchmark Richard - excellent work! And nice site to - Google Sites has moved on since I used it - well done - really like the lay out David
  11. Thanks Richard - I am using 1.25 and will get that nose piece adaptor outa there before I image again :-) I didn't use darks on this one - it was 0130hrs before I got done with the flats and as I had eggs in the image I knew this wasn't "a keeper" so I went to bed - but normally I do use darks. It was great to be out again, especially as it was quite warm and nice to have a look around the sky while the rig was imaging. I sometimes set up my 8" SCT to observe on the deck while imaging - best of both worlds :-) David
  12. :-) "Great minds think alike" I had just finished updating my Access db that I use to record my astro observing/imaging with these extra fields when I read your post :-) I'll export the data to Excel when needed for forums/blogs etc. I had a look at Filemaker once - looked good David
  13. Thanks :-) The table is from a Word document that I keep for each image and I paste it into forums' / my blog etc. for reference You make a good point there as if it was in Excel I could sort/group the data etc. Spacing was a big mistake as you can see in the image below - I think I remember screwing the filter whee directly into the flattener - I'll have to look at some old photos of the rig in action :-) ...and write it down this time lol
  14. There's a lot wrong with this image! Egg shaped stars because I didn't have the spacing right etc. But great fun to be imaging again for the first time since March - more notes in table below re processing etc. Details Object name Crescent Nebula Object ID NGC 6888 Date(s) 5 Aug 17 Telescope Altair 115mm Camera ASI1600MM Luminance 0 Red 0 Green 0 Blue 0 Ha 19x5 min Oiii 0 Sii 0 Total time 1.5 hours Frames 0 Processing PixInsight / Bias, Flats, no darks / Levels / Curves / ATWT Notes With a full Moon low in the South I couldn’t image this object in colour, but with narrow band filters I was able to get a good set of h-alpha sub frames to process. As this was the first imaging session of the year it was inevitable that things were not going to go perfectly. Thankfully the guiding with PhD 2 worked perfectly and I was quickly capturing subs. However, I didn’t have the spacing right between the camera and the field flattener and this resulted in egg shaped stars at the four corners of the image. I figured out that I had included a 50mm nose piece adapter where I should’ve just screwed the filter wheel directly to the flattener. A large note has been made :-) Amazing that I’m able to image in the light of a full Moon and get some results to practice with.
  15. absolutely loving mono imaging - full moon - no problem - the Crescent Nebula is still there to image AND I can watch the distant clouds marching past the Moon in the South :-) Loving amateur astronomy in all its many guises :-) David
