Not sure where you live but around that time there was a Bombardier Global 5000 that came out of Stanstead and flew directly south right over Gatwick at 21000feet. This type of small jet has a high tail and the rear strobe which is on the tail cone most likely lit the tail from underneath.

The glow could still be some sort of LP or just a sky gradient, should not be a problem as such. The marks, are they just dirt or physical damage?

The easiest way, ISO 800 for dim targets ISO 400 bright targets, shoot so the camera luminance histogram peak is approx 20>25% from the left. 25% will get the RAW histogram off the lefthandside.

That would be Cosmos 2457 a Russian GLONASS satellite at approx 19000 kms. Basically it's a GPS satellite that has a 11hour period.

What about some decent flats.

I would say no for both as they are not really imaging scopes. It does'nt mean you cannot all together but the alt azi mount is rather restrictive and the scopes more than likely will not reach focus for direct mount cameras. The only way to use a bridge camera is afocal because you cannot remove the lens. It may be possible to get focus with a Barlow but don't bank on it.

Found out leaky USB leads can give this type of interference. Also checkout any wall warts, some can be quite filthy.

IMO the images they talk about is what you see via the eye piece.

Here are some Slow scan tv from the geostationary sat Es'hail-2 or QO-100 These were direct off the satellite at 10GHz with a 1.1metre dish.

Optimum time, end of June after midnight. It's always quite low for the UK even in the optimum time. Get some height and no LP it's doable from the south coast.

Your well on the way, longer subs should get some nice images.

I'm under the impression the first image is straight from a colour camera, no filters apart from a cut filter. So it's not false colour or should'nt be.

Depends if you want true colour or something else. For true colour the first image , emission nebulae are not as bland as the second image. Emission nebulae should be very bright vivid colours like neon as the emission lines are very narrow. Colours can vary a bit depending on the exact elements, pink, magenta, blue and teal with brown to orange as more dust is involved.

Have used AA, PI and DSS and I still do mix them up depending how I feel. All work just fine, it's just me that kills the final image. 😜

The only way is to buy one and see, if your lucky it may be ok for wide shots.

Cannot expect to much from 2seconds but the first image is a big deal as your no doubt hooked now. 😀 Bump up the ISO, 3200 will not hurt and go for f/2.8. BTW You can see individual images because they have a tone curve applied, back of camera and software will do this. The RAW image will be very dark and lack colour, histogram hard left.

Another websdr which you might find interesting, you can listen to amateurs on the Eshail geostationary satellite. This satellite is called QO-100, the downlink is 10GHz and the uplink is 2.4GHz. https://eshail.batc.org.uk/nb/ A fun project to receive the downlink is a simple setup of an old Sky dish, a cheap LNB plus a bias tee for power. A cheap SDR dongle as a receiver should be ok.

Basically the first adapter is useless as it makes the FD 42mm flange distance bigger, no infinity focus. The second one you will need to try but it's most likely not worth it, depends on what you want to take photos of.

Have seen this comb effect on various bands but cannot pin point what does it. Normally it does not stop operations, as I run mainly digital modes it's not a problem. I have just found out I have a wide band hash on 2metres but it's mainly to the SE.

What stacking method are you using? Median or sigma clip should shift the outliers as I can see satellites trails as well., average will not shift them.

The red and green streaks look like hot pixels.

If your using a websdr it ain't amateur radio, it's just amateur radio relayed via the net. It's a good way to get familiar with amateur radio if you have no receiver. The SSTV pics you see come from the Russian part of ISS, the callsign is RS0ISS and are broadcast on 145.800MHz FM. A cheap sdr dongle should be able to receive these pics with a modest antenna. Here is a link on how to do it. https://amsat-uk.org/beginners/iss-sstv/

No it's a 12 second burst. 😀 The spikes are not the scan pattern as they should be 3.2seconds for each 7.5degrees. The each whole sector should take 19.2 seconds to scan 45degrees.
