  1. Managed to get a quick shot of Comet NEOWISE as it bumped along the northern horizon here. At least it's visible all night now in Devon - I wasn't really up to staying up till 3am and fighting the advancing daylight. Here's a quick 10 second shot, f/4, ISO3200 through a Canon 6D at 105mm
  2. Aha... one of the side effects of lockdown is that I've barely used the car so there's a DSLR in the boot amongst a lot of other stuff! Here's a quick 25 second shot taken just a little to the west of my usual spot.. And Jupiter and Saturn have made an appearance!! I can go to bed happy now!
  3. For once it's been a night of visual for me - a fair bit of high cloud drifting through but I felt tonight I'd just take it easy, starting with the moon and working my way across Ursa Major, then into Cygnus, Hercules, Aquila etc and down... Every time I image I wish I'd bought a visual scope, everytime I take a visual scope I wish I could have caught some imaging data.. tonight I wish I've brought my DSLR as the Miky way into Sagittarius is looking really bright.. James
  4. Definitely out playing tonight but with the DSLR Partaking in my daily exercise at a local beach... Milky Way rising...
  5. Lots of high cloud moving in from the south (again!) for me.. East Devon.
  6. This is me from last night in the early hours at my very isolated dark site... the bright glow in the Milky Way is actually the moon, somewhere behind my head I'm out again tonight but am closing down now for the night, I'm not as able to do sleepless nights as I used to be
  7. What he says We included alternative sources of data on Clear Outside so that people could easily check alternative forecasts ..
  8. I've just put one onto a 104mm StellaMira and it fits fine with no extra adaptors needed. Having taken it all apart again I am regretting not taking a picture! James
  9. I am a fan of PixInsight but my problem is that I so rarely get round to processing I've forgotten everything I learned the last time round so I do find the learning (or re-learning) curve a tough one. I've relied very heavily on tutorails from Harry Page here http://harrysastroshed.com/pixinsight/pixinsight video html/Pixinsighthome.html and Kayron Mercia here: https://www.lightvortexastronomy.com/tutorials.html The developers strike me as real hardcore maths/stats types - as processing is maths/stats that's got to be a good thing... James
  10. Thank you David - I’ll try anything that hides my processing failures James
  11. It's been a bit of a drought for me for imaging (and most others in the south-west UK) so I've scraped together some data taken using a scope that's fallen off a mount (!) and needs a little tweak to the optics, two mounts (one that's proven somewhat recalcitrant), all over about three years with mixed weather conditions. The changing scopes/mounts etc is an occupational hazard I'm afraid but, whilst hard on imaging, it does allow for variety . The Leo Triplet is an old favourite from my visual-only days - I like the '3 for the price of one' object thing (yep, M81/M82/NGC3077 is another favourite). A group of three galaxies about 35 million light years away they make a good set of objects to observe and image. The image below shows the faintest of trails off the bottom of the galaxy on the left, NGC 3628, (aka the 'Hamburger' Galaxy - really!?). This is part of a 300,000 light year long tidal train of stars from the galaxy and this part is probably why I'm going to redo this image properly some time - I'd love to do an image properly showing this... Due to the data being captured at different times and different circumstances I've had to crop a fair part of the image - I aligned to the little star in the middle every time but forgot to check the rotation of the camera.. every session was at a slightly different angle! Equipment: Mostly (!) Esprit 120, iOptron CEM60-EC, ZWO ASI1600MM-Pro through Astronomik DS RGB filters. Scope control, capture and guiding by CloudMaker's apps - AstroTelescope, AstroImager, AstroGuider and processed in PixInsight, all on a Mac. Lots of Pot Noodles, chocolate biscuits and tea. All subs 120 seconds, mostly at Gain 75, Offset 30, -25c. 38x Luminance, 15x Red, 15x Green, 21x Blue (click on the image for a better quality version). Annotated for reference, North is to the left..
  12. Slippery slope Martin Wow, though. Lovely image. 11 hours to get the OIII!!! James
  13. Foggy here now but only about 10ft thick... I need a taller tripod!! I also need some sleep so its pack up time..
  14. Clear here... a sizable fog bank is over the other side of the M5/ Cullompton which I'm guessing will be here soon enough. Not as good conditions as last night but two nights in a row
  15. It cleared again around 1.30am down here so I got 2-3 more hours of data. I topped up my darks whilst it was cloudy and set in a friends caravan with the heater on max and a Pot Noodle. School day today though so I'm struggling! James
