  1. Having just damaged my Lodestar x2 through my clumsiness in the dark, I sent it for repair. Just wanted to say a huge thank you to all the team at Starlight Xpress. They responded quickly to my request for service. Despite me living in France the repair was very quickly carried out. If you take out the time for posting and customs I’d say it was a couple of days tops. Great service. Thanks again. I’ve been using the camera for guiding for nearly 10 years and so pleased to have it back working again. We often complain of poor service but rarely mention it when we get first rate help and supp
  2. I have the Celestron on my EdgeHD800. It’s had issues. I had to add blue loctite to the screws as they are short and kept coming loose. It’s very noisy. If you don’t have a Celestron mount there’s no way to focus without a laptop as no hand controller. As you may guess I’m not very impressed with it. I have a ZWO EAF on my refractor. Never had an issue and have now bought the bracket to try it on my Edge. Hope that helps. Mind you it’s not going to help me sell my Celestron focus motor if I decide to ditch it!
  3. Skywatcher illuminated reticule eyepiece. It has a red crosshair pattern. I think it’s 24mm rather than the newer 12.5mm models. Great condition. Looking for £35 including postage from France. Thanks.
  4. Hi Dan. I’ve got a red dot finder and moon filter. The red dot has 4 reticule and 7 brightness levels. Comes with box and new battery. The stem is skywatcher but is plastic. The filter is a Celestron 0.9ND moon filter. Still boxed. If you are interested I’m just after enough to cover postage and a few quid on top. I’m in France so I’m guessing around £12-15 postage, so I’d be happy with £25 for the pair. Let me know if you need any other info. Thanks. John
  5. Update. Hope this may be useful to others. I have now discovered that the ascom driver for the QSI660, which you must access before you connect the camera in NINA, defaults to low gain but also will default to high speed download rather than high quality, if you took and saved any snapshot images at the end of you last session. These factors probably are the cause of the long exposure times and grainy results I got. However, after rerunning the flats wizard today the flats still seem odd. Some filters show a brighter border round the image edge. Others seem to have a more expected vignette to
  6. I haven’t tried them. They looked so wrong I thought I’d done something wrong so I deleted them thinking I’d retake as sky flats and all would be good. As soon as I started retaking they looked the same. They have a lighter border all round the edges. There’s a couple of dust motes and some odd dark patches running at an angle in the lower left. No dark corners. They look really grainy when stretched too. I think I’ll try with much lower adu target level. I can’t have exposure times for narrowband running beyond 60 seconds with a bright light panel. It would take me several hours to shoot the
  7. Thanks Steve. Sounds like I’ll have to use 2 runs of the NINA flats wizard with a much brighter light source for NB. I’ll try them again and see if they make any difference. As I don’t really see any vignetting with this scope/ccd combination I might just try to keep the optics as dust free as possible and skip flats altogether. Even those taken with lum filter and short exposures just look odd. No clear nights for a bit so time for some experimenting I think.
  8. I’m having issues getting good flats from the NINA flats wizard with my QSI660. I’ve set adu as 25000 with 10% tolerance. I’ve tried sky flats and flat panel. They just don’t look right and with narrowband the exposures are very long. I see no vignette game, indeed I seem to have a slightly brighter edge round the image and a few strange dark bands that don’t change with t-shirt, paper etc diffusing the light. I can see a couple of clear dust motes but I think there should be more. If anyone is using the QSI660 and could help I’d be very grateful.
  9. Thanks Adrian. I’m new to Pixinsight and gradually learning how to process images. I liked the colours but feel I need to get more detail out of it. More experimentation needed!
  10. Qsi660wsg-8, TSQ65 refractor, AZEQ6GT mount. Guiding Lodestar x2 PHD2. N.I.N.A. Capture software. Processed in Pixinsight. 34x300sec Ha, 33x300sec OIII and 32x300sec SII. 65 darks. No flats or bias yet. This was a quick process just to see what I’d got. Needs some work but pleased so far. Outlet 4, SW France. Any helpful processing tips much appreciated.
  11. I use the Skywatcher Star Adventurer with a Canon 7dmk2 and a canon 100-400mm L lens. With good polar alignment I can get 3 minute subs at the 100 end but only about 1 minute at the 400mm end. It will guide in RA but I haven’t tried it. It’s mounter on a Manfrotto camera tripod. Very lightweight setup. I’m pleased with it.
  12. If you get a t-ring for your dslr you can attach to your scope. Advantages are that you can control exposure times. You’d get good Lunar images with very short exposures so no need to guide. Planets wiki be very small in the frame and not very rewarding.
  13. Mine has been out under a cover for days on end and gets stored in my barn which gets pretty cold. No issues after 10 years of use!
  14. Sounds promising. Sure you’ll be enjoying using the EAF soon presuming the weather improves.
  15. Thanks David. It’s a msystery. I think I’ll just have to experiment. I have a QSI660 I could try with the scope and see what happens. As you say, if the flattener is in a fixed position then trying different spacers should make no difference. Maybe it’s the ZWO filters? But then you’d think others would be reporting issues. Hoping I can do something in Pixinsight to reduce the issue.
