Hmmm, now looking for a male-male 5521 cable rated for 10A... Any suggestions?

No more flat batteries, unless I fly somewhere. It's bigger than I need, but the family wanted a camping/emergency battery.

You mean FPS? Surely you can’t get more than 100 FPS with 10 ms frames?

I put this post in Lounge as there is no Binoculars - Imaging section

I thought the pros might do something radically different. I do 10ms as my laptop can't hit high frame rates for some reason...

I want this thing they call Kraken...

I want to see what they can do with asteroids and TNOs, which are on their target list.

They discarded 92% of frames from the first run and 96% from the second. And the frames are quite long - 10ms and 5ms in the second run. I thought they would be far shorter!

Here are the capture details: quite short sequences actually: I note they use a water-cooled CMOS that can go up to 1000 FPS if they restrict the ROI.

Getting focus perfect must be interesting...

I added another 90 minutes and can start to see some faint stuff coming through now. I'll carry on adding to this as I am still seeing improvements but I will add a few more targets to the mix each night now - I don't want to spend all of Summer on one thing! So got 40 minutes on the Veil at the end of the session: I'll try to do an hour on each every clear night. I need to get a bigger battery though...

Report 112 tripod, HEM15, RC6, FMA135 and AsiAir Mini - it's easy to carry out to my garden as a single unit.

Been there, done that! I guess it can be expected if you insist on mucking about at 2am in the dark

@Adam J I think you are right… I don’t think I need to go bigger than the 533. I plugged my scope into astronomy.tools FOV calculator and went through all the Messier objects. With an only about 6 exceptions, they all fit nicely into the 533 FOV with maybe too much room to spare. I’d be more likely to be doing crops than panos. In fact I might invest in the 0.75 RC reducer - it has a 15 mm image circle so it’s perfect for the 533, and less reduction would be a bonus I think. I am thinking about next steps for my setup. It seems the RC6 is all the scope I need, but I do have an idea for a dual image rig involving adding an Evoguide 50, so there would be three scope options on the mount - RC6, EVO 50 and FMA135. The Air can only control one camera unfortunately, but I have an unused RPI that could handle capture on the second scope. If the Pi can run a FLI 8300 (I have one in the UK waiting for my grandson to visit here) then I would have some pretty cool options. Or I could pick up an old 178MM Cool.

The mask has a strong effect, but in the negative direction. It was unquestionably a worse image - not even close.

I am wondering if I should enhance the 'close approach' algorithm for the annual highlights by adding a linear interpolation step to make a reasonably precise (give or take an arcminute) approximation of the true closest position. For objects approaching within 0.2 AU of the Earth I’ll clearly need Horizons to give true positions more frequently than daily, hourly or 30 minutes would do fine. I also added labels on the week markers on the asteroid tracks to make the zoomed in charts more readable.

Added magnitude color coding to the annual highlights list. There's a a small bug in my book - magnitudes brighter than -10 lose their minus sign (an issue in parsing the data from the NASA Horizon database). It only affects the Moon in this book. I'll fix that tonight.

After last night. I think I need many more hours to get the faint outser regions which show up on some extreme stretches.

115 subs and counting...

Well, we have clearer skies tonight, so I hope to get a couple of hours tonight.

Thanks. it was taken with my Hackstrograph v2 - an RC6 with an SCT 6.3 reducer, ASI485MC camera and a ZWO Duo filter. One minute subs, gain 200.

I think my Duo filter and GraXpert denoising did most of the work! But this is with an uncooled camera.

This week I changed from working full time to 80%, so no work for me today Less pay of course, but more time. This meant last night was an Astronomy Night, and I managed to catch 12 minutes on M27 before the weather gods realized what was going on and quickly sent over some cloud. But at least I got to set up my equipment and do polar alignment, and I shot some calibration frames afterwards, so not a total loss. But 12 minutes of M27 gives a pretty bright image actually, I can harly imagine what 4 hours would give me!

I have been meaning to get around to doing a few nights of 15-minute single subs on a lot of targets, but it needs to be a dark night with good transparency and the opportunity hasn't come.
