99% illuminated moon mosaic in 18 frames

Recommended Posts

I took this image on the 4th Nov over the space of about half an hour from 2215UT. This mosaic is made from 18 frames, each of them is 3000 frames, with the best 12% stacked within Autostakkert2. Total data size was 52.6GB - all using an ASI120MM through a 350mm newt at f4.52 with a 742nm nr-IR filter.

Each of the frames was processed identically in Registax6 with Wavelets, etc. and then saved as a fits file. At this point, I took the images into ICE and combined them into one large mosaic, and then post processed in PS (levels, slight smart sharpening, curves and background levels). I did also try using photomerge in PS CS4, but interestingly, ICE did a better job (marginal, but there were a couple of edge artifacts with photomerge). 

Beware for those on slow connections: the full size file is quite big at 7.3MB, even as a jpg...thanks for looking!

Nice panorama! (As perhaps some of you have noticed, I especially like moon panoramas. :smiley:) This one shows much detail and covers the North Pole region very well.

My first thought was: How is it possible that you covered the full moon with just 18 frames, using a 14" telescope. But then I realized that the camera was probably at prime focus of the short Newtonian. That makes sense. With my C11, using the same camera, I need at least 60 frames!

I agree that photomerge in PS isn't a good choice. I got the best results with Panorama Studio 3 Professional. But your result with ICE is very good as well. I didn't see any merger artefacts. Very good!

Thanks Rolf! Yes - a fast-ish Newtonian: less frames, but doesn't make the collimation easy compared to say an SCT! I'm also probably a bit more liable to local air currents (though being a truss, it does cool a bit quicker and doesn't have currents passing up a tube). Mirror needs another clean though...

I'll take a look at the trial version of Panorama Studio - ICE worked well here, but there doesn't seem to be a lot of control over the way the images are stitched - there are a couple of slightly soft areas which would be good to revisit, but I think I perhaps needed a bit more overlap between frames in a couple of places. 

I also need to have a look at your Firecap plugin! Very impressive work and have downloaded it already, but I didn't have a huge amount of time to look at getting it working - next full moon I'll see if I can get the process automated! Cheers!

A really excellent image, I love being able to scan over the full moon at this level of detail.

Hi Graeme,

Newtonians usually give better image quality as compared to SCTs of the same size. They need a stronger mount, though. For my Vixen Sphinx the C11 is, therefore, easier to handle. Otherwise I would love to use a large Newtonian, too. :sad:

Panorama Studio Professional 3 gives you lots of control. For example, you can edit the keypoints which are used to stitch the images together. But even in fully automatic mode it usually works very well. As far as I remember only the "professtional" version supports 16bit, which of course is important.

If you want to experiment with MoonPanoramaMaker, I very much recommend that you first get familiar with the process using the ASCOM telescope simulator and Stellarium. The exact details are described in the "Cloudy Nights" thread. Taking panoramas fully automatically is a complicated process. One should be well prepared when first trying this at the telescope.

All the best,

 Rolf

Great image, incredible clarity all over. :)

      Wow, First time I've seen the Moon through a telescope and what a sight. We had a good look at the Moon last night. It was also a chance to play around with the different eyepieces and what a difference that made. The red dot pointer was spot on after I found the little cardboard trick on you tube. Only using the 6SE in manual mode at the moment. Hopefully the cables for the firmware updates will be here today and the sky will be clear tonight. I fear that tonight will be cloudy, seems to be building up now, even looks like we may have a little rain. Looking at the moon was a little bit emotional. I am so happy we have the telescope.  One question someone may be able to help with, is there a way to make the focusing on the Celestron 6SE a little less coarse.. It's almost like we need some kind of fine focus. Don't get me wrong, the focus is great , it's just a little bit sensitive, It's almost as if it needed something with a larger circumference.
      We were looking at the moon with mouths wide open in awe of the beauty of something ordinarily we take for granted. I think we are hooked into astronomy, although there is so much to learn, at least now we have the time. We are finding that we now have the urge to take pictures, and also record our observing. Do people just use notebooks for observing notes or is there some kind of  correct way of doing things
       Thanks for all the words of encouragement

      Hi guys! 🙂
      My name is Andrew, I only just stumbled across these forums just now! Couldn’t have come across a better community to help me with some questions I have!
       
      So I’ve Come to the conclusion that I’m going to be buying a Celestron Nexstar 6SE telescope everything about it appeals to me. I currently own a much older manual celestron telescope and am ready for my first proper telescope!
      I do plenty of photography and own a DSLR and am aware that with this telescope that it comes with a software that will record video of what you’re gazing at and stack the images if I’m correct?
      because I’m familiar with normal photography and not so much with Astro photography I was wondering if anyone could help me out. For the stocking software, is that all the process completed within the telescope and no DSLR? Or is that recorded with the DSL are and then the software stacks? What kind of adapters would I need to be getting into AP? By the way I’m looking at mainly photographing the moon and hopefully get some awesome shots of the other planets too! 😄 not so much deep AP, as from my research I’ve gathered that this isn’t the greatest for it... anyways.
       
      Is it better to use a DSLR and an adapter on the eyepiece for imaging? Or the stacking and what would I need for best result stacking images, especially of planets like Saturn and Jupiter?! Are the individual eyepiece attachments you buy for the telescope, cameras in themselves? What is aci?  I’ve got no clue! Haha a lot to learn!
       
      I thought I was on the right track looking by myself for equipment and I came across the 10MP celestron Neximage eyepiece or whatever it is? I’m not entirely sure? And also what is a T ring? Is that a Dslr adapter? Does the stacking software come with the telescope or with additional purchases?!
      Sorry for the bombardment of questions! Obviously I’m very excited to get going and am very keen on getting some equipment! Any answers are much appreciated!
      Have a great day!

      Hi guys,
      So on Tuesday night I spent the evening imaging the moon with my Celestron 9.25 SCT and DSLR as shown below and am happy with the images I collated (I only took images as I did intend to take capture video but I got carried away and time was getting on).
      I have approx 350 jpeg (and the equivalent in raw) images and have used the Microsoft image composite editor to stitch the frames together without editing them first etc but I wonder if I'm going the images an injustice?
      I'm not ready to pay for editing software as I know there is a lot of very good free downloads out there and I'm asking for recommendations. Should I be processing the frames before/after stitching and what software would you recommend? Please offer any advice you have.
      I will post the resulting image once I'm happy with the outcome 😁
      Thanks in advance!

      I took photos of the flower moon at 300mm and 1.5x crop .I am using autostakkert 3 to stack the photos but I am not getting the expected results .Any recommendations?
