If it's under warranty, I wouldn't start opening it up. I know it's a pain, but wait and see what FLO says.

Looks like you had some good nights there, very nice.

Nice write-up. I use APT myself and have recently added ASTAP to it's plate solving and agree it is very quick! I did look at N.I.N.A. when I upgraded to a new capture laptop with Win 10 Pro 64 bit on it, but didn't like the layout/setup. Perhaps I should give it another go as I didn't really give it a chance.

Amazing detail in your image Ole. I love the inner dust lanes.

Another good one Simon! You've really got Mars dialled in.

Nice captures Steve. One thing I've learnt for planetary imaging, reduce your region of interest - ROI - so you only have a small area of sky around the planet. You don't need all that sky and it really drags the fps rate down. You can always add more background later if you prefer a larger frame. You'll also be able to keep binning at 1x1 so keeping more detail.

Great set of images. I love your rotation videos. Very impressive.

That's a lovely clear Mars there Tom. Your Saturn and Jupiter are showing good detail too; really obvious Cassini Division.

Lovely level of detail Geof! Nice write-up too.

Thanks Simon. Yes, they were a quick process as I was very tired that evening, only having had 4 hours sleep from 05:00 that morning. Good job I'm on holiday this week! I might stack all the images and do a de-rotate in WinJupos.

Thanks guys. I was pleasantly surprised about how easy it was to capture to be honest! Having a focal length of 7050 mm helps of course. 😉

Thanks Craig. Although we live on the outskirts of a large town, our street lights go off at about 01:00; so trying without the filter might be a good idea.

Thanks Pete. I did runs of 5000 frames, captured at about 45 fps, with an ROI of 400 x 400 pixels. I'm not at my PC so that's from memory.

Nice level of detail Simon!

Nice; even without the ADC. I had a go too last night, after doing an hour or so on NGC6826. I also got a couple of sequences of Uranus. Yet to process any of the vids as I didn't get to bed 'til 05:00 this morning.

Hi, the ASI120MC-S is really a planetary camera. With a read noise of 4.0e it would be very noisy at long exposures. It's also got a relatively shallow well depth at 13000e which means the brighter stars will burn out in long exposures. Having said that, sometimes stacking lots (couple of hundred or more) short exposures of 10 or 20 seconds gives pretty good results. At the end of the day you have to go with what you've got. Good luck and hope to see your results soon.

I wouldn't mind having problems like yours! Really nice image.

Thanks! 😊 Still got some tweaking to do with my kit; but I've got APT plate solving and goto++ working, PHD2 is guiding with sub arcsecond total RMS and Stellarium is talking to APT. So I'm a happy bunny at the moment, 'cause I'm out imaging. 😊

Taken on the night of 12 September. NGC6826 - The Blinking Nebula. This on Wiki: NGC6826 is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "blinking planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding nebula. However, it can be viewed well using averted vision, which causes it to "blink" in and out of view as the observer's eye wanders. A distinctive feature of this nebula are the two bright patches on either side, which are known as Fast Low-Ionization Emission Regions, or FLIERS. They appear to be relatively young, moving outwards at supersonic speeds. Right ascension: 19 h 44 m 48.2 s Declination: +50° 31′ 30.3″ Distance: ~2000 ly Apparent magnitude (V): 8.8 Apparent dimensions (V): 27″ × 24″ Constellation: Cygnus Radius: 0.22 x 0.20 ly Designations: HD 186924, SAO 31951, Caldwell 15 Equipment: Imaging: C9.25; CGEM (diy hypertuned); ASI385MC; Baader neodymium filter; Astro Photography Tool Guiding: Travelscope 70; SSAG; PHD2 Processing: DSS; Photoshop CS4 Extended 99 x 20" lights, of which 63 were stacked; 50 x darks; 50x bias; 50 x flats Looks like I'm going to have to have another go at my collimation. Very happy with this even so, as it's the first serious imaging I've done for sooo long! A lot more data is required to bring out the detail in the nebula. Comments/suggestions welcome.

Do you mean the moon Io to the left of its shadow?

Don't like it! As for the last one!!! How is a crumpled up piece of paper astro photography? 🤪

I think I actually prefer the mono image. Worthy of APotY!
