Toddeo, thanks.

 

I still need to try a stack since I have at least 16 subs done at the same exposure (the image above is from a single sub, ISO100, 1/4s). The stack should add a bit more detail to the sunlit portion and it will definitely help with the earthshine.

Okay, another lunar cycle has begun and last night I captured some detail on the 4-day-old moon using a C6 (A-P barlow, e.f.l. 2800mm) and a QHY5III-178C camera. Best 15% of 1000 subs in AutoStakkert!, sharpening in Registax, with final tweaks in Photoshop CC2017. I tried to capture a series covering the entire moon, but that was interrupted when I found that a very heavy dew had formed on the C6 corrector plate (there was a strong breeze coming in from the ocean and that brought both low clouds and a rapidly falling temperature as soon as the sun had set).

 

So, this may be the "best"  that I got from about seven sequences on the moon. Note the twin craters Messier and Messier A (with faint rays) near to the bottom center and the large crater Langrenus toward the upper right.

Was out this morning finishing some subs on the Crescent Nebula and before starting my darks I decided to try some shots of the last quarter moon at the prime focus of the Tele Vue NP127is using a ZWO ASI178MM-Cool camera and a Baader 610nm red filter. It was kind of tough using Sequence Generator Pro to take lunar images since the download is so slow and even the frame and focus isn't anywhere close to real-time video, but I didn't want to interrupt the cooling on the camera to switch to a program like FireCapture. So, I waited for about one second for each full-frame download from within SGP.

 

Haven't had time to process all of the subs, so the below is just one sub using an exposure time of 0.008 seconds with the maximum dynamic range gain setting in the ZWO driver. Image processing in PixInsight and Photoshop CC2017. Not bad for a single frame, and I'm not even sure I had the focus as good as it could be (it's hard to focus on the lunar features with such slow refresh in SGP).

 

Cropped and downsized to get under the CN posting guidelines.

I have been interested in the third quarter moon features of the Mare Vaporum for several years and visit the area whenever viewing permits (usually one day each month, weather permitting). My main area of interest is a feature known to some as the Hoof Print but which I call the Black Lips. This was a new discovery for me in June 2014. I'm beginning to realize that the sharper the image, the less the formation looks like lips. This is my latest attempt to image the area. Photo taken through an ETX 90 at prime focus with a Logitech webcam and processed with RegiStax 6. The scope rides on a 70's Edmund Scientific GEM. I realize that this is very primitive equipment but that's what I have. Seeing was marginal and focussing was a challenge.

 

Can anyone explain what appears to be layering of the rocks in the Montes Apenninus? 

 

Thanks,

john

Had another opportunity to get some shots of the waning crescent moon, this time on the morning of July 18. Same equipment as my last post, Tele Vue NP127is at prime focus (660mm, f/5.2) with a ZWO ASI178MM-Cool camera using the highest dynamic range gain setting, a Baader 610nm filter and an exposure of 0.015s (all from within Sequence Generator Pro). Processed in PixInsight (sharpening and histogram adjustment) and Photoshop CC2017 (more tweaks and size reduction to conform to the posting guidelines on CN).

 

I took 256 still frames, but what is shown below is a single sub and one would expect that a stack of the best subs would turn out somewhat better (and without the size reduction required here on CN, the original would be over twice this size).

 

Also, a crop showing the Aristarchus region at the full scale of the original.

James, I love taking lunar portraits too and I'm amazed at just how good some of the single frames can be with a bit of tweaking.  My single frame is a crop using my Canon 6D with my SW 120ED and ~2X barlow.

 

Being a newbie, as I understand it, using your 178 at prime focus would that be "under or over-sampling" sampling of the image?

 

Either way, nice shots!

 

Jeff

Jeff, delightful shot (of yours) and thanks for the notice.

 

Sony's IMX178 sensor is definitely under sampled at the prime focus of my Tele Vue. That scope is an f/5.2 and I'd probably want to work at somewhere between f/12 (mono) and f/18 (one-shot-color) in order to reach the so-called critical sampling with that sensor (that meaning, neither over nor under sampled).

Hello,

 

i am back here, with my new 115mm refractor and i will try to make good work with it.

 

So, my very first picture of the Moon, using my TS Photoline 115mm and an ASI178MC camera.

 

The normal colour version :

And the enhanced colours version :

The moon's southern highlands on August 31, 2017 taken at the prime focus of a Celestron C6 using a QHY5III-178C camera. Image processing in AutoStakkert!, Registax,  and Photoshop CC2017. I'm sorry about the strange orientation, this should be viewed in a portrait layout but because of CN's posting restrictions I can't upload the final image in that format.

 

I actually have the entire moon at this same resolution (this was a 1280 x 1024 pixel region of interest that I took as a highlight on tonight's moon). However, I doubt I will get this good of resolution once I process all  9 panels for the final composition -- each panel having a camera full-frame size of 3096 x 2080 pixels.

Jeff, thanks. I think I may have gone a bit too far in the scale for this last shot. I did a 1.5X drizzle followed by a reduction but the final image was still about 1.2X of the original capture (which is probably not a good idea with a one-shot-color camera). However, I know that I have a fairly good image any time I can capture the small craterlets on the eastern floor of Clavius (east is up in this image).

 

Below I've outlined the area I'm talking about --

A quick sequence taken on the morning of September 10 using a Celestron C90 (spotting scope, 90mm, f/13.9) and an uncooled ZWO ASI174MM camera (two overlapping fields to produce a full-disk mosaic). Image processing with AutoStakkert! (best 20% of 720 frames x 2), Registax (sharpening), and Photoshop CC2017 (merge, tweaks).

 

To conform to the CN posting guidelines I had to reduce the original by about 50%, so I've included some crops to show the full image scale.

James and Alain, very nice !

 

A try at a colored Moon, with the ASI1600MM-C with filters. The telescope is still the AT72ED, with a Powermate x2.5.
