Thanks. I imaged it myself last week and was wondering what it was. According to this link the name is misleading and it's not really an aurora: https://spaceweatherarchive.com/2021/11/22/3308/ "Auroras appear when charged particles rain down from space, hitting the atmosphere and causing it to glow like the picture tube of an old color TV. SARs form differently. They are a sign of heat energy leaking into the upper atmosphere from Earth’s ring current system."

Hyades, Pleiades, California and IC348
Knight of Clear Skies replied to ollypenrice's topic in Imaging - Deep Sky
Well, that's just lovely, a churning roiling dust field. I don't remember seeing a shot quite like this, showing such a coherence of the branching dust structures. Could be a consequence of such a wide field of view and scale of the region it shows. Is that all of the Perseus molecular cloud in view? Would be interesting to compare the distribution of the radio HI signal. Here's a slightly wider field of view in IR from WISE (W1/W2 channels): https://viewer.legacysurvey.org/?ra=62.1268&dec=31.2590&layer=unwise-neo6&zoom=6 The IC138/NGC1333 region is particularly interesting in IR: https://viewer.legacysurvey.org/?ra=54.4457&dec=31.8272&layer=unwise-neo6&zoom=8 -
Lovely image. There is a lot going on in this part of the sky in IR: https://viewer.legacysurvey.org/?ra=53.7107&dec=32.1558&layer=unwise-neo6&zoom=8 A project I'd like to do sometime is have a go at blending the WISE data into a widefield shot of this region.

Happy New Year everyone. Here's a wintery view of the Hurlers triple stone circle under a bright Moon, looking North towards the bright stars of the Plough. The purple glow on the horizon is a bright aurora. The Hurlers are a unique triple stone circle on Bodmin Moor dating to the late Neolithic or early Bronze Age. https://www.caradonobservatory.com/articles/the-hurlers-by-moonlight

Hard to say really without seeing any images. Amateurs do pick up transient events while imaging from time to time.

Thanks. If you put an image up I could have a go at plate-solving it, then look on SIMBAD to see if there is anything interesting there. https://simbad.cds.unistra.fr/simbad/sim-fid

Could you post an image please? Certainly doesn't deserve ridicule, it's interesting if something is showing up in your image. But it could well be some kind of optical artifact. I once had something that looked like a comet in a chain of subs but turned out to be a reflection from a bright star a little out of frame. Another time I had an odd artifact from an IR security light on a camera. Measured skepticism is probably the right approach, but dismissal wouldn't be. A streak doesn't sound right for, say, a supernova as it is a point source, unless a very bright transient or cosmic ray caused a column to saturate.

LDN1165 - Dark stuff in Cepheus
Knight of Clear Skies replied to powerlord's topic in Imaging - Deep Sky
Nice capture. I think the oval shape is an artefact due to how Stellarium displays a few selected DSOs. -
Aurora right now
Knight of Clear Skies replied to Skipper Billy's topic in Imaging - Widefield, Special Events and Comets
Missed the brightest part of the display which was after midnight but still got this: This was looking up a slope, so not the best vantage point. Would have been well worth my while to get to higher ground but the aurora seemed to be subsiding at that point and I wasn't confident in the weather forecast. The forecasts show a chance of more displays over the next few days. -

Got some worthwhile pictures from Cornwall, even though I don't have a low horizon to the North. -
Aurora - UK Tonight Feb 26th

Alert up to red again. -
Aurora - UK Tonight Feb 26th
Knight of Clear Skies replied to Gfamily's topic in Celestial Events Heads Up
Managed to get a couple pictures from Cornwall earlier this evening but I think it's died down for now. Met Office are saying there is also a chance of visible aurorae tomorrow. -
I recently signed up for a bronze plan from Telescope Live, I'm hoping to grab the occasional closeup to complement my own imaging. Here's Herbig-Haro 555 (and others) in the head of the Pelican, the data is from a 24" Planewave in Chile.

Happy New Year everyone. I made this quick video to demonstrate a star tracker in operation. Don't often see DSOs in a video but using the 35mm lens and Ha filter Barnard's Loop and the Angelfish are visible.

M31 processed with BlurXTerminator
Knight of Clear Skies replied to ParallaxPete's topic in Imaging - Deep Sky
That's a lovely rendition, full of detail and unforced colours. I like the slightly soft stars myself. -
This does look like a bit of a game changer. It may be a tad funky but it does seem to be doing a good job of pulling out detail which matches well with higher resolution images.

Such a busy region of space. My most successful Ha image from the Autumn, due to technical problems and some errors this was my longest data run. Which was still only 61 minutes. I managed to get some colour data the other night so I'll have a go at an RGBHa image when I can find the time. 200mm f2.8 lens, 1600MM cool, 61x1minute subs.

A Dusty NA & Pelican
Knight of Clear Skies replied to Knight of Clear Skies's topic in Imaging - Deep Sky
You definitely have some dust in there. In this case I wouldn't expect the visible dust to line up very well with the IR in my image, as it dependant on the illumination. I bended in the W1 and W2 channel from WISE which shows the warmer dust, which I think is heated by embedded stars and/or gravitational collapse. I'd be very interested to see what a really deep broadband image would show. There is a lot of scope for using different blends of data to emphasise different features. -
Lovely image. Can anyone else see the man taking his fanged python for a walk?
