  1. Past hour
  2. 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.
  3. I will include u.k postage.....
  4. 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.
  5. 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.
  6. Nice one....i am going my self in 2 weeks,and thinking of bringing my little Heritage 100p.
  7. Thanks a lot, love this frame of Orion and 3min subs at 200mm really is achievable with the Star Adventurer.
  8. 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.
  9. 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.
  10. 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 ..
  11. 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.
  12. 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
  13. From my flo wishlist It's Father's Day soon - I'd better start dropping hints Ady
  14. 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
  15. 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.
  16. 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
  17. I have found that sequator isn't as snobbish as dss, when it comes to poorly focused or trailed subs.
  18. Today
  19. Nice colourful and sharp cluster Neil. Interesting contrast with my M13 - a recent first light B/W image ( 30 min) with an Altair 183M (non-cooled) and coma corrector not yet installed. Your larger DSLR sensor (I guess that is what you used) provides smaller and sharper brighter stars. Bob
  20. This looks amazing! Pushes me towards getting a star adventurer as my goto system seems to have a mind of it's own lately, it's amazing the difference tracking can make!
  21. Lucky you in Oz with access to southern hemisphere skies Have you looked at SDM telescopes? New if you can afford it, or of course used if you get lucky to find one! Requesting the free info pack from Obsession on their website gives a lot of interesting information, even if you don't purchase from them.
  22. I've followed the instructions (thanks @Oddsocks) and the camera has been updated successfully. I've put it back in the freezer at around -10 degC air temperature and will start a full run of 100 x 1800s -20 degC dark frames, followed by maybe 2000 bias frames. This should show, after calibrating and stacking, that the banding has gone and give me a master bias and a master 1800s -20 degC dark to use for next season, should I manage to get any imaging done. Thanks @PhotoGav for having the same issue and posting it, otherwise like Oddsocks and maybe others, I would have been none the wiser. Cheers all.
  23. It's just that png files, like jpg, display directly on the forum so don't need to be downloaded to view them. As Dave said, slight coma, predominantly bottom right. Better than the other RedCat images shown here. Interestingly CCD Inspector gave it a 'good' result with all four corners similar and the centre slightly out of focus. Probably not enough stars for a proper assessment as it only found 523 stars. Around 3000 or more stars are needed fairly evenly spread over the image give the best results. Alan
  24. Wow! Thank you all for your recommendations. I wasn't expecting responses for some time. I will take a look at what you all have suggested with fingers crossed.
