  1. Partial Solar Eclipse - 10th June 2021 Annoyingly very cloudy during the eclipse for me today in NW UK which scuppered plans to take a timelapse, however did manage to snap this image during a short break in the clouds. Equipment: - ES102ED CF Triplet - SW EQ6Rpro - Canon 800d - Baader solar filter Acquisition: - single image at f7, exposure 1/6s and ISO 1600, colourised in PS
  2. This looks great! Thanks for having a go.
  3. Shot M 13 last night. Happy with this overall for the integration time but was quite disappointed to see that the faint stars in the central cluster were very soft, despite excellent focus with APT's Bahtinov Aid. Is this likely to be a feature of my seeing/Bortle class (6)? Equipment: - Skywatcher EQ6R-pro - ZWO ASI 294MC-pro - Explore Scientific ED APO 102mm F7 FCD-100 Triplet Carbon Fibre - Hotech SCA 1x field flattener - ZWO ASI-120MM-mini guide camera - Skywatcher Evoguide 50ED guidescope - Optolong L-pro Acquisition: - Shar

  5. M51 (21/4/21 and 22/4/21) Bortle 6, UK First photons for my first dedicated, cooled camera over the last two nights; this is 5 hours exposure from my back garden battling a 50% (approx.) illuminated moon. Keen to receive feedback, are the settings generally considered optimal for broadband in Bortle 6? Equipment: - Skywatcher HEQ5-pro (Rowan Belt Mod) - ZWO ASI 294MC-pro - Explore Scientific ED APO 102mm F7 FCD-100 Triplet Carbon Fibre - Hotech SCA 1x field flattener - ZWO ASI-120MM-mini guide camera - Skywatcher Evoguide 50ED guidescope
  6. echoing the comment above re: star field, wow!
  7. Hi guys, bought a new Canon 800d about 12 months ago, IR modded about 10 months ago. I've noticed (particularly recently) that my dark frames are becoming less and less effective at correcting for thermal sensor noise, and on closer inspection of my dark frames, this appears to be due to worsening sensor banding as time progresses. I have uploaded a series of autostretched master darks to demonstrate this effect over time. Is worsening sensor banding a recognised problem as DSLRs age? Is the sensor failing slowly? I have not checked the shutter count but suspect it'll
  8. Thanks so much, this is helpful and I see it now too. Will have a play! BW Rik
  9. Not overly sold on this result, but happy to receive feedback as always Equipment: - Skywatcher HEQ5-pro (Rowan Belt Mod) - Canon 800d (modded) - Explore Scientific ED APO 102mm F7 FCD-100 Triplet Carbon Fibre - Hotech SCA 1x field flattener - ZWO ASI-120MM-mini guide camera - Skywatcher Evoguide 50ED guidescope - 2 inch mounted Optolong L-Pro Acquisition: - Sharpcap polar alignment, ASCOM guiding/dithering with PHD2 - APT image acquisition - Lights - 77 x 180s ISO200, 12 x 180s ISO400, 20 x 30s ISO1600, 8 x 120s ISO1600
  10. Hi guys, happy with this overall, but would like constructive feedback as always. In particular, I've noticed a real difficulty with achieving nice star colour, I've managed to tease out some colour in the orange stars but really struggled to achieve any colour in the hot blue ones, even after star colour calibration in APP or photometric colour calibration in Siril. I suspect this is because my subexposure duration is so long (to overcome lack of dynamic range of shooting with a DSLR), but nonethless if anyone has any tips or tricks for this they would be greatly appreciated, thanks again.
  11. I’ll take the anti vibration pads - sent you a PM.
