From: [email protected] < [email protected]> On Behalf Of Geof Lewis Sent: Thursday, June 13, 2024 3:14 AM To: [email protected]Subject: Re: [QSI-CCD] NGC 4157 image ?
NGC 4157 is a nearly edge-on spiral galaxy in Ursa Major, located about 55M light-years away. ?Based on its apparent size and distance, its disk is about 125K light-years in diameter, which makes the galaxy somewhat larger than our Milky Way galaxy. Although NGC 4157 is quite photogenic, it seems to get little attention from amateur imagers or, for that matter, professional astronomers. ?The surrounding background in the image has many distant galaxies including some galaxy clusters at distances of 3-5B light-years.
The image was captured during 6 nights in May 2024 from SkyPi Remote Observatory using a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 for a final LRGB integration of 18.3 hours.
Thanks for looking,

Bruce,
That's gorgeous.

Moving on,
The Lycander webcam arrived today, and is actually pretty good, in
fact very good for the price, a nice crisp image with good colour.
The lens does unscrew, but it proved necessary to dismantle the
camera to fully remove it. Just two little screws as you can see.
That exposed the screw thread which is 12 mm, so my adapter fitted
ok. Unfortunately the lens holder is too far back for my adapter,
but I've scaled the Amazon one from a screenshot and you can see the
approximate sizes. Photo attached below
The distance from the front cover of the camera to the threaded lens
holder is 8.3 mm, so the Amazon adapter will easily fit with the
front cover in place. The clip arrangement can also be easily
removed by prising up the little cover on the hinge to expose a
small screw.
It self installed under both Windows7 and Windows XP, and works fine
with Metaguide (although monochrome) and Sharpcap. This version of
course is 720p so 1280 x 720. But there is also a 1080p version
shown on Amazon (1920 x 1080) for ?25. ? IF that has a larger chip
as the pixel count suggests, it might make a pretty good Lunar
camera.? Perhaps I will give mine a go anyway, even though it
wouldn't have the front cover on.
Here are the links again:
Camera?
Adapter ?

Peter.

Hi
Nicola,
Why is using the full image train crucial?? I only use Metaguide
for collimation, and simply replace my QSI 683 with a webcam or
the Altair camera that works.? Perhaps you are saying that other
items in your image train effect the collimation, so you are
trying to compensate for that?
But that could create its own problems, surely it's better to have
the main instrument properly collimated, then make sure the
downstream items are in line and at right angles to the telescope
axis, perhaps by using screwed adapters.
Incidentally I've ordered the Lycander 720P webcam for a bit of
fun - hardly breaking the Bank at ?14.26 ;-)? It will arrive
tomorrow, and I'll see what it's like for modifying - I already
have a 12mm thread eyepiece adapter on my venerable Toucam, but of
course that camera doesn't work with Windows7 upwards (I use XP in
my Observatory), and I'd need to reflash it and use a different
driver - can't be bothered to go through all that and maybe ruin
it completely!
Cheers,
Peter.

Hello Bruce,
Fascinating galaxy pair!
Excellent work

What a wonderful composition of this target. I am always amazed with the level of color richness you attain in your processing.?
Well done!
Barry

Thanks Geof and Kevin, much appreciated.

That's excellent Bruce,
I've not heard of this pair, but you've presented them superbly. I just checked them out in Stellarium and perhaps one for me to consider as they would fit nicely on my QSI583 sensor through the C14 with Optec x0.7 tele-compressor.

NGC 4618 (left) and 4625 (right) are two single-armed Magellanic spiral galaxies, so-named because of their resemblance to the single-armed Large Magellanic Cloud. ?Their asymmetric appearance suggests a strong gravitational interaction between the two.
?But professional observations indicate the level of interaction has been modest, suggesting instead that the single-armed structures are created by processes intrinsic to each galaxy.
The image was captured during 4 nights in April 2024 from SkyPi Remote Observatory using a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 for a final LRGB integration of 17.3 hours.
