  1. Hi all, Does anyone know where I can buy one of these from? thanks!
  2. I didn't take any darks as I was just testing. They would of course have been removed had I done so. I was just curious to see whether this was flexure or something else. I'll try again with some proper polar alignment and see if the problem remains. Thanks all.
  3. Thanks, that makes sense. With rough polar alignment, I shouldn't have expected too much. There's a polar alignment feature in Ekos,.I ought to invest some time with it. Thanks @steppenwolf
  4. It was guided, albeit after a very tough polar alignment.
  5. Its not an asteroid (the same effect is on all the hot pixels). The filters are supposed to be parfocal, although I didn't refocus between changes. The more reading I do, the more I think it might be flexure. My guidescope is a 50mm one with a extendable tube and helical focuser, on a dovetail with two adjustable scope rings, all attached to the finderscope mount on my imaging scope.
  6. Novice imager here with all the gear and no idea. I have an Atik 383L mono, and an EFW2 with 7 x 36mm filters from Baader. LRGB and NB. Guided by a QHY5II on a 50mm guidescope. With my first ever session with the mono Atik, after stacking my lights and combinng the RGB images together (Deep Sky Stacker) using a reference image for all the stacking, when I combined them in Gimp, I noticed that while the stars were all perfectly aligned, that my hot pixels (I didn't do darks or flats, I was just testing) were all in a line, in order. I suspect this is flexure between the imaging scope and the guidescope, but I'm not sure. Anyone have any input? Thanks all.
  7. I.PMd you twice about the FLO adapter for the flattener but didn't get a response. Is it still.for sale? Thanks.
  8. I use Astroberry - the set up isn't that difficult at all, and I'm a Linux amateur. The creator of Astroberry is on here ( @RadekK ) and support on the Indi forums is excellent.
  9. Oh good spot Peter - thanks for the heads up. It was out of stock when I first looked.
  10. Hi all, I'm trying to attached a CCD to my Skywatcher coma corrector. Forgetting the spacing for the moment, I'm having a nightmare trying to source a sufficiently deep M48-T thread adapter to cover the threads on the coma corrector and wondered what others do? The male M48 thread on the CC is around 6 mm, and ideally any adapter will need to reach the plate. I realise this isn't essential as I can always tweak the spacing further upstream to achieve the required 55mm - but if a sufficiently deep M48 female to T-thread male adapter exists I'd like one! Ta

  12. Hi all. I've just downloaded the 'official' Star Adventurer app for my Android device, and it comes with settings to control it over WiFi. Any ideas how this is done? I can't find any reference to WiFi on the web, so I'm wondering whether to wait until the next version of the Star Adventurer assuming it can't be retrofitted.
  13. Thanks guys, I didn't realise it was quite as valuable as that, I'll suggest to him that he sells it.
  14. I've been offered this by a friend, who has inherited it from his sadly departed father. A bit of digging around makes me think it's a Giro of sorts, or perhaps a copy of one. It's the head, the tripod. the second Vixen clamp and the extension bar with counterweight. While he says I'm welcome to have it, I'd like to give him 'fair value' for the mount - any idea what they're worth? It appears to be in very good condition. TIA.
