Second summer catch-up: Solar, planetary and DSO from Petts Wood

WR134 Nebula in Cygnus - HaOIIIRGB

Details here:  https://www.astrobin.com/2mk48z/G/

Dates: 4 Jul 2022 ·  5 Jul 2022 ·  6 Jul 2022 ·  7 Jul 2022 ·  8 Jul 2022 ·  9 Jul 2022 ·  10 Jul 2022
Frames: OSC 169×300″(14h 5′) bin 1×1, Astrodon H-alpha 5nm: 21×1200″(7h) bin 1×1, Astrodon OIII 3nm: 21×1200″(7h) bin 1×1
Integration: 28h 5′
Avg. Moon age: 7.86 days
Avg. Moon phase: 54.52%

Taken in early July under nautical twilight with the usual tandem set up of 152mm f/7.5 refractor imaging luminance and 92mm f/6.6 refractor acquiring OSC.

The beautiful and very intricate ejection nebula from Wolf-Rayet 134 in Cygnus.  I had never attempted this one before but I'm glad I did as it responds very well to narrowband imaging from light polluted London and the wider region is full of beautiful colourful stars and some dark regions.

WR134 is full of incredible stats including from Wikipedia: " It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun."





LBN310 also in Cygnus - Ha(RHa)GB

Another rich star field with delicate nebula filaments in Cygnus.  A number of LBN and LDN objects including LBN310.  Also using the tandem setup.

Dates: 10 Jul 2022 ·  11 Jul 2022 ·  16 Jul 2022 ·  17 Jul 2022
Frames: OSC 68×300″ (5h 40′) bin 1×1, Astrodon H-alpha 5nm: 18×1200″(6h) bin 1×1
Integration: 11h 40′
Avg. Moon age: 15.00 days
Avg. Moon phase: 86.79%




And finally last week,

Jupiter - 12 August 2022 at 4:12AM

Jupiter (and to an extent Saturn) are finally getting higher again for us in the northern hemisphere.  The second heatwave of the summer in the UK has brought above average seeing and on Friday morning with Jupiter culminating at 40 degrees altitude and the GRS transiting, I thought I'd give it a go.

Main image is combination of 8 images from 3:09 to 3:16UT in WinJupos.  Each video was 5000 frames of which best 225 were kept.

112fps / 8.77ms / 250 gain / 700 x 700 px ROI

Taken with 10" f/20 Maksutov and ASI462MC camera.

Also took an animation from 4:09 to 4:31AM:

Very nice Roberto!

The full disc (very dynamic) and the sunspot (with excellent granulation clarity) are quite dramatic.

Always good to see the planets ~ love the Jupiter video.

Another fabulous collection from you Roberto, we are going to have a hard time choosing images for the 2023 calendar with so many good ones.

Love the WR134 indeed love all of them and your star colours are excellent.

Thank you All! Hoping for good clear skies after the (very welcome) rain.

Roberto, you are even outdoing yourself! Wonderful stuff.
