Combined two sessions on M31 from Jan this year with last nights group observing session with @e-astronomer.bsky.social , @astroroyalscot.bsky.social and @andynightsky.bsky.social and processed in PixInsight. About 2 hours of data, 15s exposures, gain 60. #Dwarf3 smart 🔭, #astrophotography

And here’s the M31 image straight from the Dwarf3. About 40 minutes of 15s exposures, straight from the Dwarf3

Two more images from last night's session: Gassendi and Mare Humorum to the left, and Plato to Sinus Iridum to the right. Both best 10% frames from 2500 frame video taken with #CFF 135 🔭, #TeleVue 2.5x powermate, #Touptek 585MM camera. #astrophotography

#Aurora from South Edinburgh just now. Looking west, barely visible to the naked eye because of the LED streetlights here. 10s hand held photo with phone. #astronomy

Woken early by Felix Astronomicus and saw the sky was clear, so got a quick shot of the Moon. CFF135 🔭, #TeleVue 2.5x powermate, #Touptek 585 mono. Pleased that I got most of Hadley Rille. Best 100 frames from 1000 frame video. #astrophotography

My previous M33 combined colour RGB data from last year with L data from my new Touptek because I had not got good flats for the G and B channels. I fixed that this evening and processed 85 x 60s L, 20 x 60s G, B, and 19 x 60s R to get this image. CFF135 🔭, #Touptek ATR2600M. #astrophotography

I've now combined 85 x 60s L images from the #Touptek ATR2600 with 135 x 30s RGB from a QHY286C and some Ha using a dual narrowband filter. All taken with the CFF135 🔭 Camera orientations were different so I've had to crop. Processed in PixInsight. #astrophotography

Trying out my new #Touptek ATR2600M mono camera on M33. This is the first 24 luminance images. I'll probably combine with some RGB data from last year once the sequence is finished. Scope #CFF135 🔭 on #TTS160 Panther mount. #astrophotography

Set up CFF135 🔭 hoping to try new #Touptek ATR2600MM. But loads of clouds, so quick shot of Moon with #Touptek ATR585MM and #TeleVue 2x Barlow. Best 100 frames from 1000 frame video, stacked and sharpened in Astrosurface. #astrophotography

Combined 45 minutes L data from a #CFF135 🔭 with about 1 hour RGB data from a #TeleVue NP101 🔭 Longer term, I hope to run both scopes simultaneously to maximise data gathering in Scotland's usually unfavourable weather. Processed in PixInsight. #astrophotography

I came across some M33 data from September 2024 and reprocessed it using techniques that I've learnt over the last year. 67 minutes total exposure taken with CFF135 refractor 🔭 and QHY286C camera at -10C. This is RGB only - no Ha added. #astrophotography

Solar disk from Edinburgh at 10:28 today using SolarMax #solar 🔭 and #Touptek 585M camera. Attempts at solar photography yesterday and the day before were frustrated by clouds - as soon as I had the scope set up and focused, clouds covered the disk! #astrophotography #heliophysics
