  1. Thanks guys, I'll have to keep trying if we get any more clear skies. There a humpback railway bridge nearby where I think I may be able to get a better view of the comet from. If love to practice more with different exposure settings too. I did try a 10 seconds exposure but at 55mm there was quite noticeable start trailing. I think I may have to try multiple short exposures of 5 seconds and attempt stacking, which is something I've not tried before.
  2. Here is my first attempt at capturing a comet with my Canon 600d. I still have a lot to learn to get the best out of this camera and it's lens but I'm pretty pleased with this single exposure. This was taken at ISO 400, f/5.6 and 5 seconds shutter speed. I wish I had access to a better vantage point, the view from my back garden is less than ideal and has recently got worse with the construction of new houses behind.
  3. They are also experimenting with darker coatings on their recent launches to make them less reflective and not as much as a nuisance to astronomers. The full constellation of 20000+ satellites could pose a serious risk to ground based observation for to their sheer number and brightness, so SpaceX is taking measures to mitigate that.
  4. I've got NGC 2440, a planetary nebula.
  5. I managed to catch it tonight with the 200p dob. Kind of tricky from my back garden with the amount of light pollution around but it's definitely there and in better condition than Y4 from the last time I saw that on the 22nd of March.
  6. I see, I'm glad at least that my camera isn't duff and I need to go trough the faff of sourcing a replacement. I'll keep what you've both said in mind for the future, thanks
  7. Thanks for your reply. I have tried using the manual sensor cleaning mode but it didn't make a difference to the result, the hot pixels are still present just as bad as before. I have successfully used Photoshop (which I've never, ever used before now) to subtract the pixels using the dark frame from my last post. It produces some artefacts in the shape of small back holes where the hot pixels were, I presume with some more knowhow these could be remedied. It's not ideal and I would've hoped to be able to shoot up to 30s without a mass of hot pixels invading my image
  8. Hi all, I've been on this forum ages as a mainly observer with some planetary webcam photography. I have taken a long break from astronomy for various reasons and I've been trying to haul myself back in to the game. Since we've all but been confined to our homes I'd thought I'd try out DSLR photography since I've never owned one. I ended up buying a Canon 600d and standard 18-55mm lens this week from CEX for a a reasonable price. So far I've been pleased with it and have been getting to grips with the various settings and manual zoom and focus options, it's certainly a huge leap from a sm
  9. I've just had my refund through from FLO, I hadn't checked the forum beforehand but I suspected that rain might've had something to do with it. Like what's already been said, I'm glad the decision has been made with plenty of notice and I think it's the right call. Hopefully I'll get a chance to attend the next SP in the new year sometime.
  10. Well I came to the conclusion after chatting with Telescope House that I would have to make my own base plate to cover the hole. I ordered a piece of 2mm ABS plastic from eBay in which I marked out the screws holes and the cutout. I used a dremel tool to cut it all out, it is a little rough around the edges but fits fine and most importantly covers the hole left by the old focuser. Also the new focuser works a treat and I can get focus with all of my eyepieces, even the Antares Speers Waler, using just the one 35mm extension and the built in extender pulled out a little way. Having fine f
  11. Old topic I know but I am having the same issue. I just bought a Revelation Superfocus Rack and Pinion focuser as a replacement for the single speed crayford on my 200p dob. The hole left in the scope is too large and isn't covered by the plate. I can find no reference anywhere to a universal plate at all.
  12. Cool, could you post a picture a let me know a ballpark asking price please?
  13. I'm looking for a decent quality focuser to replace the stock single-speed crayford on my Skywatcher Dob. Ideally something such as a Revelation/GSO dual speed crayford but I could stretch to a Moonlite if it is at the right price. Drop me a PM if you have something suitable. Regards, Tom.
  14. You are right in your assumption, whilst 2 of the screw heads are well hidden by the offset of secondary mirror there is one that protrudes slightly into the light path as seen from the focuser end with the focuser tube fully drawn out to maximise the effect. The offending screw can be seen at the 9 o'clock position, the other two are at 2 o'clock and 5 o'clock or thereabouts but can't be seen. Whether or not this will impact on the views is yet to be seen but the intrusion is minimal. It shouldn't be a problem with a faster scope which may have a larger secondary that will hide over sized sc
  15. Looking for some thumbscrews to make collimation easier on my Skywatcher 200p dobsonian, I balked at the idea of spending £30+ on a total of 9 screws shipped in from the USA. I decided it would be easier to get some from another source in the UK, it wasn't. Most suppliers won't sell at a reasonable cost to the public and may necessitate ordering large quantities of one item, many don't include VAT until the checkout and even the delivery charges can extortionate for such a lightweight order and many times I could not find the correct length (this was especially true when it came to the seconda
