  1. As I said above one post above yours, its not the printing process. Its on the original: http://aerospace.firetrench.com/2014/01/solar-dynamics-observatory-sees-lunar-transit/
  2. Not accidental as in, I didn't mean to take it, but on I accidentally left a 1.75x screw in barlow on my camera, plugged it into a 2x barlow and stupidly didn't twig why the image was so dim and large, but went ahead and hit record anyway. F37.5 should be waaaaay too much for my aperture to handle (I've struggled with my 3x televue in the past) but it actually came out ok, and, Whoop!, The Sky at Night TV programme (whose flickr group I posted it to) have put it in their 'favourite images for April'. Yay! http://www.bbc.co.uk/programmes/galleries/p01x6ffc (for those who know me, this honestly
  3. Its real Or at least, its on the original picture taken by and issued from SDO. http://aerospace.firetrench.com/2014/01/solar-dynamics-observatory-sees-lunar-transit/
  4. Got a pretty serviceable couple of mosaics the other night of Plato and Copernicus. Its been almost 5 months and one nerve-wracking optics clean since I last imaged anything. Felt good being back outside again. Both mosaics were shot through a red filter using my 8 inch SCT and DBK camera. 12 pane mosaic of Plato and Vallis Alpes 6 pane mosaic of Copernicus
  5. And of course theres a big reason there to clean a corrector, the more gunge it collects the faster it dews up on a night outside and hence the more gunge it collects. Its almost an argument for regular cleaning. And yeah, you're right, the seeing has been worse than atrocious for a good couple of months now. This time last year we were getting far more clear and steadier nights, though also it was a lot colder, which probably had something to do with it, but hey, at least we had a nice summer eh! :/And i really dont get on well with collimating so im definitely not taking mine apart, but i'll
  6. Paul, i totally agree about home cleaning it. Im not ruling out a primary clean yet. Thanks for the kind words about my images as well. I really need to clean the corrector, collimate then get a good lunar or jupiter session under my belt before i decide what to do with the mirror. Funnily enough, the scope has been in my much drier conservatory since yesterday evening and those mirror splodges dont look anywhere near as bad. When i took that photo there was still condensation on the primary which make them look very white. I actually had trouble spotting them when i looked at it this evening.
  7. Lol, i doubt many of us would. It takes a real daredevil to attempt that if you ask me. You can only imagine the insane collimation that would be needed afterwards! Give me a week or so and I'll post back with the clean corrector plate pictures.
  8. Thanks Lardy, think to start off with I'm going to try baader wonder fluid applied with micro fibre cloth. Its all available through amazon so hopefully by this time next week I'll have a sparkly clean corrector plate. And a blotchy fungus ridden primary
  9. ahhh.. I've so been wanting someone to come in and say that. I really hope so. Guess I'll find out next time I try it out after the corrector clean. Many thanks Peter!
  10. Paul, you have become the legend of my thread thanks for the help, much appreciated. I'm going to tackle the corrector plate in situ for now and I'm also going to try contacting some specialist dealers to try and find one who can take on the job of doing the mirror. Unless, like you say someone posts here who has done a mirror before and its really easy (it won't be) but I know its not something I'm anywhere near the stage of tackling. Its just soooo frustrating when I look at my grubby optics. I just want to give them a good rub down! Sigh.
  11. I agree, according to Doc clay most SCT mirrors aren't protected and I can't find any info about the C8 SGT XLT series coming with protected mirrors. Great Looks like I've got the toughest cleaning job of them all. Also looks like i'm going to need to dismantle the whole thing first as most people agree that mirror needs doing. In short… I'm scr*wed
  12. Thanks Paul, good advice again. I do understand what you're getting at re: storage of the scope. I could probably address how I store it in the garage as easily as finding a place for it inside. And you're right the temp difference will be huge when taking it outside producing a lot of condensation as it cools. I'm fairly happy now to clean the corrector plate, though still not intending to remove it, but the mirror is still bothering me. I still don't know how detrimental the few small splodges will be to my images. Guess I have to clean it and see as there's no way I'm taking it apart and at
  13. Yep me too. Its going to its new home in the cupboard under the stairs as soon as I can clear enough space for it. Regarding a service, do celestron offer one? I can only find Telescope House at the moment for telescope servicing and they seem to only do meades.
  14. Yeah I've noticed condensation forming inside the plate at night too which is making me worry about its internal state, but the thought of taking the plate off fills me with so much dread I'd prefer to clean the outside of it in place and hope that does it. I've been storing it in my garage in a polystyrene lined box but I'm thinking now its clearly too cold and damp an environment for it.
  15. Thanks regarding the cleaning brew. Don't you have to get exactly the right proportions of each in or you'll have too much water/alcohol? Do you think this is a better bet than wonder fluid for the corrector?
  16. Thanks so much guys, really appreciate the advice. I don't know really what to do about the primary as I daren't attempt to dismantle the thing to get at it. I think I may need to content myself with cleaning the corrector, collimating it again and drying the whole OTA out thoroughly with desiccant gel packs before using it again.. and hoping for the best. Couple of spots on the mirror can't affect it that much right?….. so is this the correct wonder fluid?: http://www.amazon.co.uk/Baader-Optical-Wonder-Cleaning-Fluid/dp/B001ILNDOA/ref=sr_1_1?ie=UTF8&qid=1388652147&sr=8-1&keyword
  17. Hi all, I'm after a bit of help. I've been using my Celestron C8 SGT XLT for 3.5 years now and I live in a very damp area of the UK so over the years I've used it in some truly horrendous conditions and the fight with dew is constant and grinding (I use a dew shield and low settings on a hair dryer). Recently my images have been well below par and I'm really starting to wonder if my scope should be serviced/cleaned in some way. So I thought I'd post a few pics here in the hope that some of you guys could give me your opinion on whether or not I should attempt some kind of maintenance program o
  18. Nice shots Stuart, and great to see them at such a large scale. I'm starting to think something's up with my scope, or was the seeing just rotten last night and you had a clear patch? I had a terrible night fighting ridiculous quantities of dew and ended up with yet more mediocre images. Starting to worry that 3 years of conditions like that has plastered a lot of damp related crud inside my corrector plate. You don't know of any good SCT dismantling and cleaning tutorials do you? Nice to see that large white cloud formation in front of the GRS properly in your shots though. Great job! very e
  19. Ah yeah, I remember those images. Not a bad night at all. I can't see how the police could be suspicious of any of us skulking around our gardens at night in full face balaclavas and carrying something that looks at first glance like a big gun.
  20. Yep, add me as a plus one for the hairdryer crew as well. I use mine copiously as I live in the more high altitude hilly regions of Bristol so its always insanely dewy. I sometimes worry what the neighbours must think though when they hear a hairdryer blasting out in the garden next door at 3am. Really does the job though. Thats a great vid. Looks like the seeing was pretty good that night as well, at least... compared to recent times. When was this? wish I'd been out then. Do you have any images from that night?
  21. Very impressive first effort! a damn sight better than the first time I made an animation. Very smooth as well. Really like the small scale to accommodate the movement of the moons. Nice one!
  22. Nice shot Neil, the better conditions are far more evident in that one and fills me with hope for my next run at Jupiter. I had other commitments last night so didn't make it outside but it certainly looked like a wet old night when I put my head out of the door briefly. I could almost have swam through the air! great job!
  23. Fantastic, great animation! nice work Dror. You certainly put the hours into that one eh! You're lucky you're not trying that over in Britain right now. The seeing has been so bad in the UK lately that things barely hold steady for more than a few seconds at a time, let alone long enough to make an animation!
  24. 27 million you could get a C14 with one months interest on that. Probably. Sigh. My car cost less than a C14.... Gotta be in it to win it.
