Light from the edge of that HUGE lens is being focused to the center and into view. Try seeing it from the far domino, If the far domino can see the lens from behind the front close domino then this "trick" works. This effect would not be seen with a small lens. Its like driving behind a truck and you cannot see what is in front...so you move to the side to take a peek. You are just acting like the HUGE lens. The telescope would have to be very large...Extremely large

OK, its only £50, not £500. I checked the net and there are a lot of Pi cameras claiming to be High Quality Pi cameras....but they are NOT The Sony IMX477 chip ! I found this site for UK that does sell the correct Chip even if they do have a typo in their Spec saying 3 megapixels. lol. It is the 12Mp sensor. High Quality Pi camera with Sony IMX477 sensor. Enjoy Dave.

I've not heard of 5V powered hubs before. I know they can supply 5V, especially the Active Hubs powered by +12V power supply. Some have several USB3 ports and the end one or three sockets, with the 5V, is usually for charging iPhones etc. Such as this USB3 with charging ports My USB 7 port active hub is fully utilized now. I have my rig and several USB drives connected to it. My plan is to move the 7 port USB onto my rig, so only the cameras/filterwheel etc are connected and next to my laptop have this beauty for all the USB Drives and anything else I wish to attache to it. USB3 Powered hub

As I am looking to upgrade my setup in a few months time ( all things being equal ). I too am very interested in this thread. Dave.

That's a great M106. Very nice.

You could try CdC. Download the latest Updates for Asteroids then change the time back to when the image was shot! Is the streak as a moving dot on each sub? Or just a streak on one sub? The reason I ask is, M45 streak is a constant brightness all along its length. On the NGC 2903, it appears to change from light to dark, left to right.

Looks better to my eyes That's a nice images. You have the extended dust too. Very nice.

That would be something I would like to know more about. It sounds interesting.....And could persuade me to lean toward the 16" more

I took a lot of 300s exposure on M57. It was hard, for me, to keep the background while toning down the bright object. So, I redid the exposure using 120s. My processing skills have never been that good 30 x 120s with Atik 4120EX OSC on C11, Mesu 200. SGPro, PixInsight,PHD2 Thanks for looking.

Congratulation James. Thanks for being here 🍷🍻🥳🔭

And the final one. Oh, and its possible to add flats and darks to these images so would be better quality. Not added here. the zoomed in again but a few minutes later...details on image.

That looks great

OK< After 5 mins of playing with it, I can say.....drum roll !!!! 😛 Its easy to use and fun too. And best of all. its free I will be using this quite a lot. Thanks for highlighting it. I'm currently imaging NGC 6503. Here's a 600s sub from SGPro using the Atik 4120ex on C11. The second one is the ZWOASI183MM Pro on a much shorter scope...TS65EQ,. Satcking many 60s, first wide, then zoomed in using mouse The TS 65EQ at full screen...14 stacked, a total of 900s Zoomed in 120% As I said, its fun. I do like it Dave.

I will try it tonight as I have the ZWO ASI183MM just sitting on the TS65EQ. On top of the C11 which will already be imaging using the ATIK 4120EX

Apart from these great images from tooth_dr here Check out Astrobin for images taken with the ED80. https://www.astrobin.com/search/?q=ed80&d=i&t=all

Re-done with more care. 300s was too long for this on the C11. Maybe 120s or 180s would be better. Here is M57 reprocessed in PixInsight. Thanks for lookinh.

Took this last night and did a quick process this morning. Will do better later. So far looking good Darkened the background a bit too much and contrast too high...Will process more. C11 on Mesu with ZWO ASI183MM PRo and IDAS LP filter. Pixinisght. 32 x 300s Atik 4120EX OSC camera. Thanks for looking

Looks like moisture to me.

A quick reprocess. This site shows all the failings lol.

Taken last night. WiKi - NGC 6951 (also catalogued as NGC 6952) is a barred spiral galaxy located in the constellation Cepheus. It is located at a distance of about 70 million light-years from Earth, which, given its apparent dimensions, means that NGC 6951 is about 100,000 light-years across. It was discovered by Jérôme Eugène Coggia in 1877 and independently by Lewis Swift in 1878. It was a clear dark night last night. I removed my LP filter as I was having imaging problems and not sure what was causing them. I should crop the edges too as this is full image. Thanks for looking. Using C11 on Mesu 200 with Atik 4120EX OSC camera and SGPro, PHD2 and PixInsight. 22 x 600s

Chris Lintotts gives a mention of them in this months Sky at Night magazine.

How did you obtain the image? Did you use Dithering? Everything very bright has dark patches around them. I'm sure it can be improved upon. Its a good try

Thanks for the links Göran. I was looking at Kurious George's images yesterday. WOW!! Some amazing shots there. The 24" at £56k is just above my budget Ole's images are very impressive too. Look at the IOTD and Top Picks he has!! This is the type of stuff I would like to do more of, when conditions are good. Still being processed, from last night. Snipping tool copy. NGC 6951 using the C11 at 2800mm and Atik 4120EX 3.1um pixels. 22 x 600s But I also realise we don't get conditions as good as last night that often here. I am starting to think that the APO is the way to go. I still have the C11 for the really deep stuff on good seeing nights. But if I want to get exceptional quality right across the image AND be able to use the scope more often than just look at it....It looks like the APO for UK skies is a better choice.
