Starship Asterisk*

Orion at the beach. Saturday night was a beautiful clear, calm night with the tide out. A campfire behind the headland added colourful smoke and made the scene more atmospheric. This is a stacked and tracked shot. 20x 2min for the sky, blended with a 3min foreground shot of the Oregon Coast at Hug P...

Here is a 12 pane full frame Mosaic of the Witch Head, LDN 1616 and Rigel area, bordering the Orion and Eridanus constellations. This has 156hrs of LRGB exposures taken over 2 years. Taken with a Tak FSQ106ED and Atik 11 meg CCD camera from my remote observatory in the South of France Thanks Tom O'D...

Northern Scutum: A six Pane Mosaic of the Northern area of Scutum in LRGB. Taken over two Summers with a Tak FSQ106ED at 0.53m. Total 66hrs exposure. I always love looking at this part of the Milky Way. To me it seems almost as bright as the core of the Milky Way, and I always wanted to shoot this i...

Lunar Eclipse with Mount Jefferson. This is a single frame shot of the Moon at approx 04:45 on Wednesday morning while the Moon was leaving the Umbra. The morning sky allowed me to shoot Mount Jefferson and the Moon in a single shot. It was a super viewing experience, and well worth the long drive a...

Perseid from early morning 12th August 2020 from Baltimore County Cork Ireland. The Moon was 7 degrees above the horizon and lighting up the foreground, but the Meteor was bright enough to shine through. It left a trail that lasted for a minute or more. Single 60s exp, 14mm, ISO 3200, F/2.8 static t...

Orion 400hr Mosaic. This is myself and my friends Olly Penrice joint effort on Orion from 2015, but it now up on my site as a Zoomify image. The zoom size is still only 40% the full size, and can be viewed in the link below. https://www.astrophotography.ie/mosaics.htm Takahashi FSQ106N / FSQ106ED, A...

Pi Scorpii
12hrs of RGB with 2 hrs of Lum.
This object never gets higher than 19.5 degrees from my observatory, so this was a very tricky data capture and process.

Hi All Here is a 15min stacked background image of Orion, blended with a 2min foreground image from Natural Bridges Oregon. This was taken on March the 11th with a Canon Ra, and 14mm Samyang lens. ISO 10000 for the stars and 1600 for the foreground. Each sky shot was 20s unguided. I took this while ...

This is a 25 pane mosaic of Cassiopeia taken at 530mm focal length. There are 350 hours of exposure in the image taken over 5 years. The image is dominated by the central Breaking Wave Nebula spreading out from Gamma Cass to the Pacman nebula, but many more Sharpless nebula, clusters, and NGC objec...

Thanks Ann I m delighted you like it. With your username of 4725A, I m guessing you like Blue Stars like Gamma Cass. Tom This is a 25 pane mosaic of Cassiopeia taken at 530mm focal length.

Excellent image Peter.

I love the detail that the IR gives compared to the Optical versions.

They have a Stars and Nebulae category.

I will never stop campaigning for the rights of planetary nebulae!

Its worth a shot.

Moon Illusion Tom O'Donoghue Dublin Ireland Here I attempted to show how the Moon appears a different size by our eyes, compared to how a camera sees it. I used a different zoom for each rising Moon against a set 70mm zoom for the camera's representation. Canon 5D Mk3 70-200mm lens https://www.flick...

Thanks for your reply Ann, glad you like the image.

[ I love it! :D Because I am a diehard fan of stars that are not only blue but intrinsically bright as well, Gamma Cas is obviously a favorite of mine. And because of my love of Gamma Cas, I pay rather close attention to any picture of this star, as well as any portraits of its accompanying nebulas,...

Here is a video I made from 30 single frames on the 12th of August 2016. The smoke trail from a bright Perseid can be seen up to 13minutes after the meteor passed by. Each frame is 25s, f/2.8, and ISO 3200. The video is shown at 6 frames per sec. Thanks Tom. https://www.youtube.com/watch?v=_i_DULan-...

Here is a video I made from 30 single images during the Perseid Meteor Shower. In the right hand side of the video the large meteor left a smoke trail that was visible on the following 27 frames, or for about a further 13minutes. All 30 images were taken with a Canon 5D Mk3 and 14mm lens, at f/2.8, ...
