  1. I could see it's brightness last night but that was through the murk - hence no stars visible at the time. I don't really have anything to properly image planets. I await some clear nights for the stars to appear... Louise
  2. I can't see any stars but can see Mars! Louise
  3. Well, the original stainless steel legs, with the inner legs and feet, weighed 4.1 kg. So a total saving of 4.1 - 1.5 = 2.6kg - which is quite significant. Of course, if I ever try it out outside I'll need level ground or some way of levelling the mount. If needed I could put something under one leg - I'm sure there's a way round it! I'm a little old lady so the weights of mounts and tripods ++ have stopped me from taking kit outside as I have to navigate two flights of stairs. I have a Star adventurer but I never got it to work properly (must have had a duff one) and a guided EQ3 pro on the Al tube legs seems a much better way forward. Louise
  4. Put the new 16 gauge legs on earlier today. Looks the same, ha ha but it must be ~1.5kg lighter than with the 10 gauge legs . No sign of any clear skies. July has been awful here. I've seen glimpses of Mars rising in the East a few times. - it certainly stands out, even through the murk. At least it's getting darker earlier. Winter's coming! Louise
  5. Thanks. I don't think vibration will be a problem. I'll only be using it with the 300mm lens pictured above Louise
  6. I've done it and replaced the original legs with aluminium ones ok (see above). I'm not using the inner leg, unless I find I have to. Louise
  7. The 16-guage tubes arrived today . Much lighter, but seem like they will still be fine. Since I fitted the 10-gauge ones I've had nothing but cloud so they haven't even been tried. There's a faint possibility of some clear spells tonight but I won't hold my breath. Will try and fit the new, lightweight legs tomorrow. Louise
  8. I would suggest using a magnifying glass (head mounted ones are good) and a air blower (as used to clean dslr sensors). If necessary, you could use a small artists' paint brush to dislodge anything. You may have been lucky and not got any dust on the sensor. However, if it was in my living room, for example, then no such luck! Louise
  9. Hi Assuming that you have one of these and it looks like this: The reddish appearance is just a glass window to protect the sensor. If you have a colour version I think it will also be a UV filter. You really don't want to remove the glass and get dust on the sensor! Hth Louise
  10. Hi You have to have the camera in a scope to get an image. Leave the glass window alone! You use the scope to focus but the focal point of the scope has to be on the sensor. Louise
  11. I was just talking about the mount, not the scope Louise
  12. By the way, I take it the mount is pointing close to North when you calibrate (always have DEC Compensation checked too) Louise
  13. Might there be any nearby members that could give you a hand / fresh pair of eyes? Louise
  14. Hi Knobby You shouldn't need to nudge a belt driven mount in order to calibrate - that probably indicates a likely balance or setup problem. You should be able to get a perfect L-shape calibration, especially with an oag (the RA and DEC axes can be assumed to be orthogonal and obviously should be with an oag). Louise
  15. Personally, as it's a brand new replacement mount and still appears to have the same issues as the original, I think I'd first look elsewhere for the source of the problems. I may be wrong but it just doesn't seem likely that two new belt-drive mounts would appear to have the same/similar problems. Louise
  16. I just (02:30) had a look in the North East - couldn't see anything Louise
  17. Remember, it has to be balanced vertically as well as in RA and DEC . Always make sure guide star is not saturated and has a good snr (or best you can get). Not sure what you mean by "the best tighter than the 2mm flex" ?? So with oag what fl are you using in PHD2? I've never used either a oag, or a SCT, or other long focal length scope, so I don't know how good the guiding would be expected to be. I'm sure someone else on here will have had the appropriate experience . Louise
  18. Hiya It might just be the seeing - what was tracking like with the Guiding Assistant (i.e. guiding off)? You shouldn't really be getting any backlash with a belt mod (I've said before, I'm sure!). Calibration should be very good lines. I still suspect you may not be perfectly balanced. When you run PHD2 for a while are the points on the target clustered around the centre (good!) or to one side (bad!)? If to one side that indicates imbalance. Another possibility is guide scope flex if guide errors are random. What was your star profile and snr like? Louise
  19. New tootsies came today . They needed a couple of layers of tape to make a snug fit but I was expecting that. Of course, with the current arrangement I have no way of levelling on uneven ground so I'll have to stick to somewhere flat. It's still a little heavy for me to carry (I'm a wimp, I know) though I probably could just about manage it with a laptop and small battery in a backpack. I think the 16 gauge legs will be better in terms of weight but it could be several more weeks before I get them. The weather forecast is mostly cloudy anyway .
  20. I found I only needed a small sliver of tape on the tube to get a tight fit. That let me easily drill holes for the grub screws. Seems all very solid with the grub screws in. I'll assemble the legs on to the base and take a pic. There are (were!) these clear sort of washers where the top fitting goes into the base and the bolts go through. I can't see any real need for them so not bothering to replace for now. Louise
  21. I've ordered the 16 gauge tubes now. Delivery time is a bit slow - could be a couple of weeks, so I can try the 10 gauge out first. I'll try some different things for holding the tubes in place and see what works. Cheers Louise
  22. Ok, thanks. The grub screws aren't essential though with thinner metal I could easily drill some holes for them plus use tape, or possibly some sort of glue, to hold the legs in place. At the same time I don't want it to be too lightweight for imaging purposes. I suppose I could order the 16 gauge legs and try them out . Might glue stick glue be good enough to hold the legs in place? Cheers Louise
