  1. Excellent WiFi goto mount from Skywatcher. RRP is £345. Works with the Synscan app available for Android and IOS. Basically it creates a wifi network which you connect your phone / tablet to and all the goto and tracking features are on there. Near mint. Includes 12 volt power supply and cigarette lighter power cable. £225 Basedi n Gloucestershire, but may be able to meet somewhere mutually convenient.
  2. Hi all, Does anyone know where I can buy one of these from? thanks!
  3. 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.
  4. 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
  5. It was guided, albeit after a very tough polar alignment.
  6. 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.
  7. 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 imagi
  8. I.PMd you twice about the FLO adapter for the flattener but didn't get a response. Is it still.for sale? Thanks.
  9. 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.
  10. Oh good spot Peter - thanks for the heads up. It was out of stock when I first looked.
  11. 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
