  1. Hi everyone, My friend purchased a Celestron SLT102 last year, and through moderate use, an error code 16 comes up on his NexStar computer (provided with the scope) and now it does not work at all. He called Celestron and was advised to update his firmware, but he is not confident to do this as he is worried that it may damage his computer. He has since sent several messages to them asking if he can just send his computer directly, but they have not yet replied (this was well over 2 weeks ago). His telescope will still be under guarantee and he has a copy of the receipt.
  2. Hi All, I have installed a Skywatcher EQ5 Dual Axis Motor Drive onto my Vixen EQ mount, and wonder if anyone knows the size of the round DC connector that goes into the controller from the powerpack? I was hoping to buy a lead which connects to the controller DC inlet to a USB connection as it seems a bit wasteful using 4 x D batteries. I think using rechargable D batteries may wear out the battery pack over time and is a hassle putting them in and out. With a USB connection, I can just plug the controller directly into a rechargeable power pack that I have already. Hope some
  3. I have been using the Polar Finder app, but find after around 30 seconds of exposure on my driven mount through my Skywatcher 200PDS the stars start to trail. I have since installed the polar alignment app and star gate PA apps to compare, and they all give polaris different positions at the set time and location. Can anyone advise what the most accurate polar alignment app is? Cheers.
  4. Thanks for your replies guys. I just wanted to reduce some vibration by stopping my mirror from flicking up when taking pictures, but just glued the mirror to the 'up' position. Rather than holding the mirror once glued to dry, I just put the camera in clean shutter mode which keeps the mirror open and allowed the glue to set for an hour or so. After doing the above, the camera seems to work perfectly, but obviously I can't use the viewer, just live mode which is fine. I am hoping to attempt the astro modification myself soon as I have downloaded a PDF for doing this. If I ma
  5. Cheers for the advice. I just ended up gluing the mirror to the open position, rather than removing it. It's an older camera anyway and so think I'll try and remove the filter next to the sensor myself (so I can get more of that lovely red light to enhance nebulousity). Worst case scenario I break the camera, best case I've saved a few Bob.
  6. Hi All, As I have a Nikon D3200, I was wondering if anyone knows a good company who can convert this camera to allow for much better H-Alpha light to enter the sensor? I found someone who could do it, but was charging an extortionate amount (£275 + VAT) to convert it and had over a month turn around time!! Ideally I'm looking for somewhere who can do it for around £100. I tried contacting 'cheapastrophotography', but no one has been back in touch (it is my understanding that he can convert cameras for around £75). I was also wondering if anyone has removed their mirror
  7. Hi All, I currently have a Nikon D3200 DSLR camera and wondered if this camera type has 'exposure delay mode' to minimise vibration when taking long exposures? Effectively, in this mode (if this camera has one), the mirror is raised a couple of seconds before the sensor activates (I assume that the reverse happens when the shutter is closed again). I have had a look in the manual as well as going through the settings and can't find a way of doing this. Failing that, can the mirror be removed completely and the camera still operates (obviously I would loose the abilit
  8. Thanks for your reply. I read somewhere that it depends on the DSLR used whether using the field flattener will achieve focus. Not to worry, I may cancel my order for the 50ED and order a 72ED instead. All the best, Dougie
  9. Hi All, I have purchased a Sky-Watcher EvoGuide 50ED Guidescope and am waiting for it to arrive. Currently I have a Nikon d3200 DSLR and wonder if it can be fitted to this scope once a field flattener is fitted (i.e. will the camera still focus)? Hope you can help. Dougie
  10. Hi All, just to let you aknow that the polar scope for the Skywatcher EQ5 fits my Vixen GP DX EQ mount perfectly . Thanks again for your help guys.
  11. Thanks for your reply guys, its very helpful. I have since purchased a Skywatcher polar scope (EQ5 version) for my Vixen mount, but will return it if it does not work and purchase the updated reticle as advised. If it works (and I remember) I will let you all know if it fits or not. Thanks again, Dougie
  12. Thanks for your help guys. Thanks for your reply and advice Neko. In order to remove the Vixen polar scope, would I be correct that the grub screws need to be loosened first, then the polar scope unscrewed? I am waiting for an Allan key (wrench key) to be delivered so that I can remove the scope from my mount. I hope you can further advise. Thanks agian, Dougie
