  1. This morning from a cloudy Caithness.
  2. Imaged with the Altair Astro 60 EDF, Lunt CaK B600 and ZWO ASI120MM. 09.18 UT.
  3. CaK shots of today's AR2827 and 2829. Scope was the Altair Astro 102 ED-R stopped down to 70mm. Filter was the Lunt CaK B600 and camera the ZWO ASI120MM. The stopping down really has improved the image.
  4. Thanks Carole! I have needed to find a particular workflow for the PST HA shots as all my cameras give me newton's rings (sometimes with the exception of the DMK 31 but I find the resolution is less than optimal with that cam). The rings are actually the worst on the Altair cam and yet also the easiest to remove with the Photoshop FFT plugin. In addition I need to use a flat frame to counteract the uneven illumination given by the PST. The CaK is much easier! 😆
  5. Cak done with the Altair Astro 60 EDF stopped down to 40mm and the Lunt CaK B600. DMK31 camera. Ha is a 7 pane mosaic done with the double stacked Coronada PST and Altair GPcamV2 mono. Seeing was not great, especially for the CaK.
  6. Cak taken with the Altair Astro 60 EDF and Lunt CaK B600. Ha taken with the double stacked PST. Camera was the Altair GPcamV2 mono. Sun in CaK Sun in Ha
  7. Hi there! Brian from Caithness here. I'm a long term astronomy addict, have been since I was 9 when a neighbour showed me Saturn through a vintage 3" brass refractor. I've been into imaging for the last 10 years or so, starting with a webcam. Well, things have moved on since then! Looking forward to contributing to the forum. 😀 Best wishes, Brian
