Last night was the last session after a whole week of clear night time skies. Almost unheard of. The almost full Moon was 90° away so I'm pleased to have got a half decent image. I've used the same flat frames for a week now and there is evidence of new dust halos. The dwarf Galaxy in the corner is the Garland Galaxy, NGC 3077. M82 is just out of frame.

The Moon

Leo

08/04/25

When the Moon is close to full there's not much chance of capturing any nearby deep sky targets. So here's the Moon. This is 5% of the frames from a 1000 frame video. Plate solved on Regulus and slewed across to the 85% lit Moon in NINA with coordinates from Stellarium. Then switched to SharpCap and recorded the video.

The Splinter Galaxy

NGC 5907

Draco

Edge on Spiral Galaxy

06/04/25

48xLRGB @ 4 minutes, 3 hours total

This edge on Spiral Galaxy sits in the constellation of Draco the Dragon. Captured under clear skies but the mount seems to forget how to guide when the humidity rises so I stopped the sequence after 3 hours when the reading reached 99%. This is probably a better target for the 9.25" SCT.

The Dark Shark Nebula

LDN 1235

Cepheus

Dark Nebula

05/04/25

60xLRGB @ 5 minutes, 5 hours total

Another clear night, fifth in a row and more to come. This is the Shark Nebula, a faint cloud of interstellar gas and dust 650 light-years away in Cepheus. There are a couple of dim blue reflection nebulae as well. The dust cloud obscures the background stars in the shape of a shark. The target was low in the sky and the first quarter Moon was in the sky too so the shark is difficult to see. The big fish slipped silently through the water!

Canes Venatici Galaxy

NGC 4395

Canes Venatici

Spiral Galaxy

04/04/25

80xLRGB @ 4 minutes, 5.5 hours total

The week of clear skies continues. The Canes Venatici Galaxy has a very low surface brightness so I am pleased how this has come out. 14 million light-years from Earth. Classified as a Seyfert Type I galaxy and known for its very low-mass supermassive black hole. Not much detail in the spiral arms but the central bar is clearly evident. Perhaps 5 minute exposures would have been better. An Ha filter would have picked up more. The lack of guide stars after the meridian flip bought the session to an end.

The Leo Triplet

Leo

Spiral Galaxy Group

03/04/25

58xLRGB @ 4 minutes, 4 hours total

This is the Leo Triplet, three spiral galaxies at different angles, Messier 65, Messier 66 and the Hamburger Galaxy. They make a nice group that fits in my 660mm FL refractor field of view. The image is upside down because that's the best balance I get on the telescope. And I quite like the anthropomorphic pareidolia effect too! Besides, there is no up and down in space, no one can hear you scream either! Captured last night, a shade under 4 hours of 4 minute exposures.

The Pinwheel Galaxy

Messier 101

Ursa Major

Spiral Galaxy

02/04/25

60xLRGB @ 4 minutes, 4 hours total

Galaxy season is upon us and South East England is experiencing uncommonly clear night time skies. This is Messier 101, the Pinwheel Galaxy in Ursa Major. Another one I've done before but not in wide field. A couple of years ago there was a supernova in one of the spiral arms that was clearly visible as bright as one of the foreground Milky Way stars, but now it's faded. This is just over four hours of four minute exposures from last night captured with LRGB filters.

The Whirlpool Galaxy

Messier 51

Canes Venatici

Spiral Galaxy

01/04/25

45xLRGB @ 4 minutes, 3 hours total

Messier 51, also known as The Whirlpool Galaxy is interacteracting with a companion galaxy. The pair are 31 million lightyears away in. M51 was the first galaxy to be classified as a spiral galaxy by William Parsons, 3rd Earl of Rosse, using his 72-inch reflecting telescope at Birr Castle, Co Offaly, Ireland, he found that the galaxy had a spiral structure, the first "nebula" to be known to have one. I went to Ireland and visited Birr Castle and the telescope, known as the Leviathan of Parsonstown for my 60th birthday. I'm always reminded of the trip when I see this galaxy! I've imaged this one before at a longer focal length but I like the wider field of view I'm using now.

The Jellyfish Nebula

IC443

Gemini

Supernova Remanent

04/03/25

90xL 25xRGB @ 4 minutes 11 Hours total

An unprecedented week of clear nights allowed imaging sessions on five nights in a row! Three of those ended prematurely with only a couple of hours of photons captured before the 99% humidity ended the session for the night. My longest ever exposure but still quite a dim target. The bright star is Propus, Castor's left ankle.

The Twinkling Comet Cluster

NGC 2420

Gemini

14/14/25

98xL 27xRGB at 60 seconds - 3 hours. Guiding still not working.

A tad under three hours.

The Tadpoles Nebula

The Tadpoles Nebula and the Letter Y Cluster

IC 410/NGC 1893

Auriga

30/01/25

500 x 30 seconds each, LRGB (3:1:1:1) because my guiding calibration refuses to work.

A tad over four hours.

Significant because it's my 100th astro image! 😁

The Flame and Horsehead

The Flame Nebula and the Horsehead Nebula

NGC 2024 and B33 IC 434

Orion

09/01/25

This is from the third clear night in a Week! I have captured both the Flame and the Horsehead before but not together. The bright star is Alnitak, the Eastern star of Orion's belt. The Flame, next to Alnitak, but in front of, not associated with it, is an Emission nebula and the iconic Horsehead dark nebula Barnard 33 is on the edge of the HII star cloud IC 434. I captured this with 60 second exposures to help prevent Alnitak from becoming too saturated. 219 x 60 second LRGB. 3 hours 40 minutes total exposure. Humidity and frost threatened the session again so I parked the scope at 22:20 just prior to the meridian flip. There was a waxing gibbous Moon not too far away so I'm pleased this came out as well as it did. The PI Lockhart Gradient Removal Tool is a life saver!

The Orion Nebula

Messier 42

NGC 1976

Orion

08/01/25

The Orion Nebula M42 is a diffuse nebula in Taurus just below Orion's belt. It is one of the brightest nebulae and is visible with the naked eye. My mount refused to guide so I captured this one with 30 second exposures. 144 x 30 second LRGB. 1 hour 12 minutes total exposure. Humidity and frost ended the session again.
