  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.
