  1. I'm still very much learning and here is my image of NGC6820, an emission nebula in the Constellation of Vulpecula. My Skywatcher 200p certainly needs collimating and i need to invest in a field flattener. I've used the Hubble palette with narrowband filters and an ASI 1600 mm Pro camera. I've oversaturated the colour, but all in all i'm very pleased with it
  2. Greetings all, any RASA 8 owners out there? I'm wondering what 2" filter drawer you are using. I know that back focus is important so i don't want to get the wrong one. I've seen a ZWO for £79 and a Starizona for £139. Any recommendations would be great. Cheers
  3. I purchased an ASI1600mm pro (mono) camera 6 months ago and what a great camera. I'd been using it without any issues, however, after a 4 week break i went back to it and took a 5 second test shot only to see an horrendous artefact on the left hand site of the image which did not lessen over time. I removed the camera, and noticed a streak of some residue running down the RHS of the sensor. I have had the camera in the warm house now for a couple of days and the residue hasn't evaporated. Any ideas what it could be? I'm concerned the residue may be coming from the sensor itself due to some fault. I haven't tried to clean the streak off the sensor as I feel that removing the lid of the camera to get at it may invalidate the warranty.
  4. A happy accident! I was expecting a cloudy Welsh night, so to capture the movement of the clouds, I placed my canon dslr camera on a tripod and positioned it above Lake Vyrnwy and took 15 second exposures with a delay of 5 seconds, thus creating a time lapse covering about 2 hours. To my pleasant surprise, 28 seconds in to the timelapse the clouds opened up and Comet Neowise suddenly popped in to view. I assumed our celestial visitor would have been closer to the horizon and hence not visible from my location. But nice to have captured it with a normal camera and tripod. BTW, a couple of shooting stars are also visible, if you can spot them Also, does anyone know the bortle scale of lake Vyrnwy? The clear dark skies appear darker than anywhere else i've been to including Kielder forest. Lake Vyrnwy.mp4
  5. @x6gas Appreciate your kind words
  6. @MarkAR Many Thanks. Regarding the elongation of stars around the edge of the image, i put it down to coma, although i may be incorrect.
  7. A couple of clear nights last week and i managed to capture 3 hours of data on the eastern veil nebula, 1.5 hours Ha and 1.5 hours Oiii ( Meade 480mm F6 refractor + ASI1600mm camera) and combined using the HOO pallete. Processed in Pixinsight and Photoshop. My processing skills are still very basic and I am still very much learning the dark craft.
  8. I've never tried that with my OSC bit i assume the image will not be a higher resolution as a mono camera due to the Bayer matrix.
  9. I live in a Bortle 9 area and even on a dark moon free clear night i can count no more than a dozen stars in the sky. I suffered terribly with OSC imaging, even with a LP filter and processing was a nightmare as my images were incredibly noisy. However, recently i decided to go the NB route and a few weeks ago i took a 1.5 hour exposure of the veil nebula in HA and 1.5 hours in Oiii using a skywatcher 200p reflector telescope and ASI1600mm camera. The resultant HOO image is below. ( The image with the diffraction spikes) Compare that with a 5 hour OSC image i took a couple of years ago from the same light polluted back garden, i used a Meade 80mm refractor telescope with an Atik 320e camera and Light Pollution filter. I would have needed to go to a dark sky site for a comparable image. Galaxy imaging will still be a problem with the RGB filters, but at least the nebula images will be a lot better
  10. @AbsolutelyN Good call. If the problem persists, i'll change the cable, see if it makes a difference.
  11. @johnoelliott I've taken the red pill i think @andrew s last night was the hottest night we've had this year (25 degrees) and the camera cooled to -20 below ambient without any issues. Never have issues with cooling. @tomato I've opened up the bad images in pixinsight and the vertical lines are still present. However, last night i didn't have any issues at all with vertical lines having imaged for about 2.5 hours. Will keep an eye on it.
  12. I have loaded the fits file in Deep sky stacker and the vertical lines are still visible unfortunately.
