  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 smartphone and compact digital cameras. Tonight though I tried out long exposure for the first time using some settings similar to what I used on my old IXUS 95; around 10-15 seconds exposure, ISO 100-400 and F3.5. The initial shots seem hopeful but the images are pockmarked with hot pixels. The blue, red and white pixels all seem to be in the same place and are present even with shots with the lens cap on. They can be removed with the camera's noise reduction setting but that requires another exposure of equal length to be taken right after the first. Are these hot/stuck pixels typical of what I should be experiencing or is this abnormal and indicative of a defective sensor/camera? Cheers 😁
  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.

    I think you have captured the supernova, well done :) It is the middle one of those three bright-ish stars that go left to right and begin just "upwards" from the core. Go straight up from the core, at the first bright star go right and that bright star is the SN.
