  1. I would say its the other way round in regards to the 'LX200' I would say that maybe that scope that was put together for someone, its got the same looking focuser as the Schmidt but the rest is the same as mine, Ive not seen that finder scope before either but its bracket is matching the same green paint finish as the rest of trim. Its an interesting one!
  2. Not one of these unfortunately I don't think as its got the same standard secondary mirror that mine has!
  3. Difficult because if that is the case they have done it really well!
  4. I dont think so, the secondary mirror looks exactly the same as mine! I would have thought that would be different if it was a Schmidt Newtonian - looking on google, I have found the Schmidt Newts, doesnt appear to be one of them, its a strange one!
  5. Lol the other thing is that the 'Orion' logo txt is white where as in all other pictures of these scope's, its black! Same font though!
  6. Quick question, has anyone heard of an Orion Optics 'LX200' I've seen an old 8 inch Newtonian pretty much exactly the same as my old Orion Optics Newtonian f6 (white and green) but Ive never seen one from research that was an 'LX200', the sticker lettering looks authentic but the only LX200 I know of is a Meade scope!? A picture of mine for reference!!
  7. Ive never quite understood most of astrophotography let alone all this calculations stuff!
  8. Thanks, appreciate the help as always. I will put this together with what Ive been reading and make some small changes and go from there
  9. When you say 'read correct;y' you mean from the blurry picture? By imaging scale you mean the imaging camera's Pixel scale which with my canon 600d and 600fl scope is 1.5 so as you says needs to be 1.1 or less, if its 1.53 then that's why I had star issues in my last session. Or do you mean the 3.44 Image scale of the guide scope would then need to be under 1.7 ? When you say exposure time, you mean the number to the right of the 'stop' symbol on PHD2 which i currently have set to 2s !?
  10. PHD2_GuideLog_2020-09-09_215827.txt Ive found the logs, here are a couple from my last session. PHD2_DebugLog_2020-10-09_205113.txt
  11. I'm trying to use my down time as productively as possible so I'm now going to try and understand my guiding graph/settings a little better. Up until now all Ive known really is to make sure the TOT reading stays under 1 and your good!, it has been doing that fairly well, keeping between 0.4-0.8 most if the time but really does get upset sometimes and as you can see from the picture, the graph gets pretty crazy. Ive been doing a lot of reading myself and have read that if its doing this I can lower the 'RA Aggressiveness' setting to 70-80% (currently on default 100%) so I may try that and also tweak the 'Min motion setting' There's a great document called 'Understanding PHD2 and getting it to work properly' that Ive been reading and it helped me set things up at the start. In there it talks about the Calibration step size, the example given for the writers set up with a pixel scale of 2.67 arc-secounds per pixel, he sets the steps to between 2000-2500ms, he states that if your pixel scale is higher then to up that amount, mine is 3.44. In PHD2 I have changed mine to 3000ms to start with but it wont allow me to change this in the advanced section settings and keeps it on the calculated '1950' for the guide scope details I have put in so not sure what to do here? The guiding can get upset after a dither, I have read that if the Dec cant recover well after a dither then to dither only in RA, from reading up this doesn't seem to be a good option and produces 'walking noise' I want to clarify in PHD2, what is the 'Guide speed n.nn x sidereal'? is, is that the Guide rate? Mine is on 0.5, it also states in the document to set that to 1x so should I? What are the readings to keep an eye on, in real simple terms? My graph can look crazy but what are readings besides the TOT that I need an eye on to help me tell how the guiding is really going? I believe there are some in regards to the image pixel scale? I'm not sure how to get the logs files from my sessions so currently I only have to below cropped image for you to go by and it would be good to get that settled out. i know there's lots of factors, I have been reading but lets start with the good basics, and as you know I can struggle to understand things so I simple terms please! To add, I know about the Guide assistance but a little worried i wont really understand it at the moment.
  12. Sure, just check the max weight capabilities and you should be fine.
  13. Same here, didn't take me very long at all before going onto imaging, I now very much enjoy both Imaging and visual.
  14. I started out with a decent mount which is really one of the most important bits of kit so it can handle the 650fl absolutely fine.
