  1. that's awful. yes i think there are a lot more of us out there than we know. my original post was deleted without explanation, I'm surprised this one has stayed up tbh but pleased you took the time to add your experience. My mount too had a dead zone and was hard to balance but was told it was normal and would need running in. that was obviously just a delaying tactic as it never loosened up and in fact got even tighter in use. I have managed to get it adjusted to where it no longer seizes up but I still have trepidation when using it that it will fail again. I havent done any guided long exposure with it yet, it seems to track ok for planetary so hopefully it is now sorted. it's just been a colossal waste of time and money.
  2. I had even worse problems with them. He just keeps fobbing you off with story after story and promise after promise. My mount was not tuned properly the first time which he owned up to and second time when it was finally returned after months of being told it would be coming "the next week" it was missing the Azimuth adjustment bolts and was seized in RA. Shocking for a company that big themselves up on quality. There were so many inconsistencies in the explanations he gave each time the mount didn't arrive that I don't think he actually does much to these and it's a big con. I was promised progress photos and test graphs but these never appeared despite repeated promises to send them. The warranty is a joke. I ended up getting my mount fixed myself at my own cost. Please think carefully before trusting your mount to him, you'd probably do better having it serviced by some of the guys at your local astro club and it will save you a lot of money, time and stress. Clear skies everyone.
  3. These are a good price, has anyone tried them?
  4. Unfortunately theft from cars, particularly hire cars used by tourists is very common in Tenerife. So much so that often hire companies remove the parcel shelves to discourage tourists from thinking they can hide stuff in the boot and be safe. The best advice is don't leave anything of value in your car even if it's just for a few minutes. There was a recent story of a woman whose handbag was stolen from her car at the side of the road while she took a picture of the sunset from just yards away. It's been going on here for as long as there have been tourists - I know, it happened to me in 1985!
  5. We have an astronomy group on Tenerife now TAS - Tenerife Astronomy Society. There is a group page on Facebook. We generally meet monthly and members are often out and about with their scopes and cameras in between and would be happy to try and meet up with you. Hope this helps.
  6. We are a newly formed society on Tenerife and the first! Tenerife is officially recognised as one of the very best places in the world to see the night sky in all of its glory. Its high altitude, clean and dry air coupled with a general lack of clouds means stunning conditions for stargazing and astronomy. NASA calls Tenerife one of the "four windows on the Universe" and its observatory is one of the most significant in the world. These stunning conditions are available just an hour's drive from the sun-soaked coastal resorts. Our society is a place for people with an interest in the beauty of the night sky to come together to find or share knowledge; to meet, share experiences and help each other benefit from one of Tenerife's most amazing natural resources, its very dark skies. We meet every month at Casa Zaguan in Vilaflor where we have a roof top observation terrace with a number of telescopes. Visitors and new members are always welcome so if you are coming to Tenerife on holiday, please stop by our Facebook page and say "Hola!". https://www.facebook.com/groups/tastro/
  7. Sick of the clouds in the UK, I managed to get my 200p newt, HEQ5 mount and tripod into hold luggage with Jet2 and out to Tenerife on our summer holiday. My observing spot wasn't the best as it looked across roofs that had been heated by the sun all day but despite the less than perfect viewing conditions, I managed to get my best image of Saturn to date. Well worth transporting all that gear! I've since established a very good location high in the mountains where the air is cooler and much clearer so I'm looking forward to my next trip very much! Camera used was the ASI224MC with Powermate 2.5x and a 2x X-cel barlow. 3 AVIs stacked and combined in Winjupos.
  8. That's great to hear - I've been fretting a lot about it - thanks for taking the time to respond
  9. Thanks Michael - are you saying the rotational position of the secondary within the corrector plate isn't important then and all I need to do is re-collimate?
  10. OK so good news is that the fastar retaining ring came loose and I have been able to remove the secondary. The secondary cell has a reasonable grip on the corrector so I think i can get away without needing to tighten it up if I remain careful in how much I tighten the Fastar retaining ring. The bad news is that I can't see any alignment marks on the corrector plate or secondary cell to help re-align the secondary cell. There are two letter "A"s hand written in green ink on opposite sides on the edge of the secondary mirror itself, one is a lot fainter than the other, but I can't see what they are for. Any suggestions?
  11. So, it's sounds like it's not difficult a thing to remedy but does require removal of the corrector. Did you remove just the plate or the entire front assembly?
  12. Thanks for the reply Waldemar. The corrector plate isn't rotating, just the secondary within it. I have no idea how the secondary unit fixes to the corrector but it appears that this is the problem. Your advice about teflon grease on the release ring is a good idea.
  13. Apologies if this has been discussed elsewhere, I did look but although there are some posts on this, they are for different models of 'scope. I recently (January) bought a new Celestron C9.25 Fastar. I have had the secondary out previously but now it does not come out, instead the whole secondary assembly just rotates when i try to loosen the retaining ring. I don't want to go to the trouble of boxing this up and sending it back if it is an easy fix to secure this again and get it re-aligned (I'm used to the fact that astronomy equipment often needs some hands-on treatment!) but having said that wouldn't want to undertake something that might cause more problems or invalidate any warranty. I'd appreciate the thoughts of members with more experience of this model of 'scope than I have. cheers
