Yes it does, mostly, as long as I have a decent number of subs to stack. I was just pointing out the sheer number of subs affected, and it's getting worse.

Around 50% of my subs contain at least one satellite trail where ever I aim in the sky, apart from the polar region. Sometimes I have to resort to tedious manual removal of them. It is only a matter of time before satellite pollution will surpass light pollution as the main obstacle to DSO imaging. What a horrible thought !

Nicely done.

188 hours - I don't want to hear that ! Yes not that far from you but I'm near the coast and on the edge of Exmoor National Park with the highest land in southern England, both of which seem to conspire to produce eternal cloud. But, when it is clear my skies are really dark and I can image without filters. Once we've got climate change licked there'll be no stopping me !!!

Excellent. Oh for 40 hrs of clear sky ! Think I've had 4 in 2024 so far. Nice colours and contrast. All that integration time pays off.

Excellent rendition of the elephant's trunk. I too have a quattro 10 CF which is an excellent piece of kit as your image confirms. No longer made, so must be collectors items now!

Excellent. I'm a big fan of dust and you have recorded it in spades here !

I like it, particularly the blue grey trail

Thank you for that info ! To get to my observatory and observing area I have to climb 12 very steep and narrow steps, which I do with my heart in my mouth each time I carry a heavy and delicate telescope up them ! That is why the RASA has not seen much use until now. Interesting about the internal reflections with wider imaging train. I opted for 54mm as the camera and filter drawer are 54 and I have an askar 54mm adjustable tube. This is an excellent piece of kit - you can adjust from 16 to 20mm in 0.05mm increments with precision and without having to dismantle anything. I replaced the celestron 48mm adaptor with a 54mm one made by precise parts in USA. So far I have seen no evidence of internal reflections. To be honest, the vignetting is not bad and easily correctable with flats it's just more than I was expecting. I'm now looking forward to doing some narrow band, but it's forecast to be a wetter than average autumn, so it remains to be seen how successful that turns out to be !

Excellent. Great colour and detail. Well worth all the effort.

Thanks for your comments Jim and I hope you get your RASA 8 sorted. They are the sort if scopes that require a certain amount of dedication, and certainly not grab and go !

I've had my RASA 11 for 4 years now, but never really got to grips with it as it's such a pain to set up and take down, especially when the clouds roll in as soon as its all set up and ready to go. My skies never seem to be clear enough for long enough to make it worthwhile. Now that it is permanently set up in my observatory it is ready to go at a moments notice, so I can start to use it as it should be used. Four things struck me with the RASA 11 :- 1. It is damn heavy ! 2. Nice round stars right to the extreme corners of a full frame sensor. 3. More vignetting that I was expecting, even with 54mm connection between camera and scope. 4. Cable management is a bit of a brain teaser ! The Veil and USA nebulae are two bright and easy targets to test on, and I'm quite pleased with these first results - taken as always in the hazy skies that exist between the passing cloud masses. Veil - 75 x 30sec at gain 300 taken over two nights USA - 31 x 30sec at gain 300 Camera ZWO ASI 6200 MC Pro Celestron / Astrodon RASA LPR filter. Star spikes added to cover a multitude of sins ! Comments for improvement most welcome !

Love the grey ghostly spur bottom right. Best part of the image for me, although the rest is pretty decent too !

Nice capture, and a hint of those elusive outer shells just starting to show.

Thank you. Endless cloudy skies have forced me to develop a skill for extracting more from less data !
