  1. 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
  2. Thank you David - I’ll try anything that hides my processing failures James
  3. 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..
  4. Slippery slope Martin Wow, though. Lovely image. 11 hours to get the OIII!!! James
  5. Foggy here now but only about 10ft thick... I need a taller tripod!! I also need some sleep so its pack up time..
  6. 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
  7. 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
  8. I'm losing Ursa Minor now from the north... luckily I'm imaging to the south! mayve a few more minutes..
  9. We might be looking at the same band of cloud... Well to the north still though for me ..
  10. Trouble is, it looks like they're coming from your direction!
  11. High clouds are slowly moving in here in East Devon, maybe another half hour or so... pity, it's the first time I've gotten out in months!!! Crossed fingers for tomorrow night, although late nights on a school night are never a good idea! James
  12. I’ve never looked back after getting a pair of these: https://www.baffin.com/products/85920000 I can’t for the life of me remember where I got them, a fisherman’s shop up in Lancashire I think but they’ve kept my feet comfortable in the cold (-15c coldest use) and haven’t been too hot either when the temperature has been higher. I went a size higher than my feet are which allows for thick socks but makes walking awkward if I’m not wearing thick socks
  13. Hope your recovery is quick Stu.. Cloudy here in East Devon - clear night predicted tonight for several days but it’s turned out cloudy Maybe for the better as tonight’s a school night so to speak. James
  14. I’m exactly the same and struggle with crowds - so I’ll be lurking behind some seriously nice kit on the Ikarus Imaging stand - do come and say hi James
  15. There aren’t enough clear nights to make a difference. Says the definitely not waif-like James..
