  1. Past hour
  2. Sorry, I didn't pick up on this point. You seem to have on/off/on 3 position switches anyway for the battery so that's fine. You still only need a single pole switch in the battery +ve connection as when that is in the centre 'off' position the battery is disconnected power wise. The battery -ve terminal can be permanently left connected to ground. You can if you wish leave it as you've drawn it and it will be fine. It's your choice. As you say the motor switch only needs to be a 2 pole changeover switch but if you're happy using the three position switch you have, there's no problem. Alan
  3. I had a chance to try this tonight, and that's exactly what I saw with the Nirvana. I spent an hour going back and forth between all my eyepieces. Astigmatism is apparent in the ES 24/68 and ES 6.7/82 but to a lesser extent. The Speer WALER 10/82 was by far the best, showing hardly any astigmatism at all! In conclusion, the 16mm Nirvana is not perfect but it is not that different from other eyepieces I have been happy with. Using the Nirvana as a finder eyepiece draws my eye away from the center and out to the very edge however.
  4. Well I’m not sure. In SGP I go for 30,000 - 32,000 or thereabouts. That’s always worked for me. Have a go at a range of settings and see what works best.
  5. From Portchester: Lights in the sky approx 40 deg ele, east azi
  6. You have just blown my mind with that Andrew I am now gripping my chair for dear life as I contemplate hurtling through the universe with my infinity of masses at break neck speed May explain why I'm finding it so difficult to lose some weight ; is that the ultimate delusional excuse "I'm over weight because of my chosen reference frame" . I like it. Jim
  7. Looking forward to this. Hope something I want comes up
  8. Honestly I would think about a 130PDS and a 2 inch corrector to go with it. Either that or a 500mm or shorter refactor, its always going to be difficult to get good results out of a scope made for visual use.
  9. Today
  10. I will include u.k postage.....
  11. I just got notified by OPT (Sorry, @FLO, I live in the states) that mine is shipping. Keeping my fingers crossed for a good unit. Of course, considering what you all have posted, I would honestly be happy with any of them compared to what I've been using which is just a Canon kit lens.
  12. In essence that's what I meant Adam. I've been comparing images taken with my Canon 1000D (on 650/130 and 150PL reflectors) and new 183M on the 650/130 reflector. The smaller sensor/lower resolution of the 183M (in conjunction with the scope optics) seems to show brighter stars as larger for the same image fov. So yes, the image scale is very important and a good CC may make a useful difference. I'm pondering how an M13 will look with the 150PL (skies allowing). I think that brighter stars will look large but with the image scale M13 will also be larger. Then there are the aspects of arcsecs/pixel and slower scope to consider, so it may not be worthwhile.
  13. Nice one....i am going my self in 2 weeks,and thinking of bringing my little Heritage 100p.
  14. Thanks a lot, love this frame of Orion and 3min subs at 200mm really is achievable with the Star Adventurer.
  15. Yes that is about my FOV with the Barlow. When I originally started exploring imaging, I had a Sony a350 and bought a T ring with nose piece as a kit. I paniced when I couldn't get focus until I removed the nose piece and screwed the 1.25" adaptor directly to the T ring. When using the Barlow, I do end up with a lot of focuser tube exposed.
  16. Having a week in the sun in Lanzarote. Evening meal and a few sherbets and when back at our hotel Room, dark and facing south, I get the bins and star map out. Spent some time on Centaurus, which is low in the south even in lanzarote. Great views of Globular cluster omega Centauri even though only 10 degrees or so above the horizon on the meridian. Very obvious in bins and no effort at all to find it. Much more obvious than M13. spent time in the Antares area and bagged messier globulars that are very hard to see in UK. Corvus, Libra and southern Ophiuchus. Lovely to see Jupiter at a reasonable altitude in Scorpio. I’d forgotten what it looks like almost, it’s been so low in the UK for seemingly ages now. lovely to have clear nights regularly. Shall miss this when I come home to the grey and wet.
  17. Hi John , thanks ... I'm very pleased with the mount TBH , as you can see the guiding/ tracking is pretty good .. the diffraction spikes were added in PS . I like them .. however , I still need to have another play with these images ..the red version has a lot of green stars especially when viewed on here .. and I would like to try and get some more goldish colouring on the Hubble version .. The shots were taken with my Altair 130 .. but ignore the heading on the PHD pic , because it says Celestron .. just haven't Sussed out where I can change it ..
  18. Both of the previous launches I got ready to try and image it from where I live. Glad to see it get launched. Very nice video. Thanks for posting it. Seeing the actual adjustments was great.
  19. Alan That's great, I guess some of your and Hugh's knowledge must be rubbing off on me. I'm not as quick a learner as I once was I'm afraid. Oops on Point 3, yes that was what I meant. With all that confirmed I'll get on with the trial wiring. Thanks, Peter
  20. From my flo wishlist It's Father's Day soon - I'd better start dropping hints Ady
  21. Thanks for all your replies and comments. Great photo of your telescope Mark. Unfortunately I have no practical skills so would not be able to make any adjustments as mentioned. Also I doubt that I would be able to collimate it if necessary. I have a bortle 8 sky so what could I expect to see through it apart from the moon and bright planets. I would like to see some of the colourful doubles in the night sky , but I can,t even see Albireo at mag 3.1 with the naked eye.! So presumably deep sky objects are out of the question. Chris P
  22. Thanks. I’ll give it a try. Paul
  23. I am not sure that a camera can provide smaller or sharper stars that is down to the optics. Its difficult to compare unless you are sure the image is presented at the same scale, also i suspect your coma corrector has a large part to play here.
  24. HI all, Hoping this has been encountered before by others... For many months now I have been running EQMOD, Cartes du Ciel, BackYard EOS, PHD2 guiding, and Astrophotography Tool - with no problems. Now, I keep getting the message in the title of this post. Have tried a number of remedies - i.e.: uninstalling & then reinstalling EQASCOM and Astrophotography Tool... etc. Also tried using one of the repair tools that you download from the net - but these only do a partial scan of your system and then they want $30-40 to "get the complete package" - would rather not do that. All this started RIGHT AFTER - the latest "Windows Update" - a couple of days ago. Is there any way to get rid of the this Runtime Error 55 - File already open - cause its preventing me from running EQMOD
  25. I have found that sequator isn't as snobbish as dss, when it comes to poorly focused or trailed subs.
