A 100% saturation reduced sharpened incamera from the previous nites series and luck is still holding but barely !

all 4TOE afocal 62mm apo 400mm fl Evolux

Not good skies with high thin clouds and a moon frost ring a couple times and then super clear but very shifty seeing.

Six going on seven clear evenings with moon dropping just below 60° now.

Sinus Iridum Mosaic v2

 

Mosaic featuring the Sinus Iridum (I guess it's featuring a lot, but it's my personal favorite part), taken with 5" SCT, ZWO ASI662, and 850 nm IR filter. Composite of two ~30K frame stacks, no barlow used. Captured 2/20/24, seeing average (which is pretty good around here!)

 

EDIT: replaced with slightly sharpened version. Seemed like downscaling this for the web made it need a touch of sharpening in photoshop.

Thanks !!

It was held at the eyepiece braced unsteadily or you'd have seen a hundred times more so no solution yet in sight for my digiscoping stuff so maybe forget that expense entirely IDK but it'd still be neat to have a firmly braced devices picture to wow people with.

Edit AND a better device !

Taken Thursday night through high, thin clouds and jet contrails using a Sony NEX-5R and a Sarblue Planet Mate 60 (the latter a 60mm aperture, f/12.5 Maksutov-Cassegrain). This is a single, still frame taken from a fixed tripod. Image processing with Photoshop 2024. There are additional details in the image captions (click on the preview to see the full-sized image -- although reduced to 87% to conform to the CN posting guidelines). North is oriented up.

james7ca, you've posted an excellent capture. We must have been shooting it at almost the same time; features and highlights in both our images are almost identical, although your image has much greater detail than my lowly iPhone grab.

 

I don’t usually capture 98+% moons, but it was interesting to learn more about features at the western edge; your shot was very nicely done.

Got the Celestron C6A-XLT out again, with the ASI678MC Tuesday night the 21st. Conditions were great, above average seeing and transparency. And for the first time I used a UV/IR cut (totally forgot this camera needs that in my first two sessions). Though my previous shots showed good detail, I do think this session was a tiny bit better.

 

I'm working on a whole-moon mosiac I took, hopefully I got the whole thing lol. But in the meantime here is a single shot, actually this one was testing out a smaller ROI. For some reason I am not getting anywhere near rated speed on the 678MC. Taking full resolution shots was only 14fps??? Advertised at 47.5? The below shot was ~1800x1200 ROI it managed 54fps. Though all my mosiac shots are full res shot at 14 fps. Stacked best 250 with Autostackert, sharpened with imppg. A few tweaks in Dartable.

 

Tycho, and toward the lunar south pole:

Thanks Bob, I'm unfamiliar with that crater so I'll have to look it up later.

sure, I was as well. It might be too far south to be picked up.

 

Lunar South Pole Terrain In Coded Color (SVS5127   lola Sp still 4k).tiff
 
 
I didn't see any structures that would correspond so far, but it was discovered in the 17th century, so under some conditions it should be visible.
 
Im going to see if I can see the crater tonight.
 
Funny thing is that it is an odd place to position a lander (Odie, Odysseus) , since it is thought to be in a dead spot for Earth's radio emissions. Good place for a radio telescope, but I would think might be not so good for communications with it.

 Taking full resolution shots was only 14fps??? Advertised at 47.5? The below shot was ~1800x1200 ROI it managed 54fps. Though all my mosiac shots are full res shot at 14 fps. Stacked best 250 with Autostackert, sharpened with imppg. A few tweaks in Dartable

 

I just got my ASI662 and also going through a learning curve. If you're using FireCapture, make sure "High Speed" is checked under the "More" menu in "Capture." On mine that buys me about 15 fps at full resolution. It goes from maybe 87 to about 107. One other thing is potentially your cable. If for some reason you are not using the original one it came with, or if you are using an adapter for USB-C like I was, you may get rate drop. For example, I had a Transcend USB-C to USB hub that was rated for USB 3.1, and I was getting about 20 fps less than the plain $9 USB-C to USB A adapter I got at Walmart of all places.

 

The other other thing could be exposure times. There's only so much time in a second. If you divide 1000 by your exposure time in milliseconds, that's your maximum FPS regardless of your other settings or your USB-cable. So in a perfect world, with no data loss from the cable and no processing time for the camera, you can shoot at 71ms and get 14 FPS. If you were, you could shoot a faster exposure and raise the gain to raise the FPS.

Thanks for the info, I will have to check for this high speed setting, I don't remember changing it before. I have been having a weird problem where FC is resetting all my customizations when I load it up for the first time in a while for some reason.

 

I'm using the supplied USB3 cable, its worked fine with other cameras. And I am not exposure limited, I shoot at 10ms or faster. I have been able to get upwards of 200fps with ROI on my 178MC.

Tycho, and toward the lunar south pole:

...

That's a very good image from a C6 and you did capture the area around Malapert A (the landing site of Odysseus). You can locate that region by extending a straight line from the center of Tycho through the center of the crater Moretus (the latter is the prominent crater above the limb and centered -- horizontally -- in your shot). Moretus has a central peak and looks similar to Tycho (although further south). The landing site is right on the limb of the moon, but in sunlight and the general area is definitely visible in your image.

 

The following short link to the LROC Quickmap shows these craters and Malapert A (labeled with their names):

I suppose if all else fails, it might be worth checking the cable itself against another one. It doesn't seem like it would be the issue if you are able to use it with others. Could it be a driver issue? I notice the Windows driver was updated last november. If you had previously installed a driver for a different camera before november, perhaps this model requires something more up to date?

undersampled, so not so great for details. This is my DSO longer FL setup, but decided to shoot the Moon anyway.

 

South at the top. Note the shadowed region at the top. Probably where Odysseus is located. Full Moon, but this location still is in the shadows. Still going though some closer shots to see if I can identify the crater.

Don't know. I wonder if its just that "high speed" setting or whatever that was, I need to check that. I hear USB traffic can make a difference but not sure how to adjust, its at default I believe it was 100. I've never installed any drivers and using Linux, it just worked, so not sure but I'll look into it. Anyhow, don't mean to detract from all the moon images, carry on. waytogo.gif

You guys got me thinking, so I went ahead and did my own annotation on the original image, it seems JimFR was right on but I'll do my own version as well...

Click for larger res on a-bin

 

And thanks james7ca for the crater map link... I have a really nice moon globe from Mapsoft but it is missing the Malapert crater label.

 

And I just realized this image was the goof... only 15 seconds (I stopped it early for some reason), when I had been taking 2 minute videos. 250 frames stacked out of 810. However it looks just as good as the longer version.
