  1. Recently I bought a ZWO ASI178MM for planetary/lunar/deep-sky imaging and last weekend i had clear skies so I was able to capture videos of the moon in two panels. I have already processed the videos in AutoStakkert, I used 3x drizzle because I intend to print the image so now I have two 120MB TIFF images that i would like to combine in a two panel mosaic. I tried doing it in Hugin, a free panorama stitcher but the program crashes due to the file sizes being too large. I have searched for tutorials on using DynamicAlignment in PixInsight but it seems to me that i'll need a reference image to be able to create mosaics in PixInsight. Is there any way to go about this, I feel like this should be a pretty straightforward job but I am not very experienced in PI so I would really appreciate some advice. I tried using DynamicAlignment as you can see in the attached screenshot but the result was just a cut version of the target image, aligned perfectly to the source image. It would be perfect if it didn't cut off the lower part of the target image.
  2. Thought people may like to see my recent custom design for my SkyWatcher Heritage 130p... As a big Apollo misson geek, and not being a fan of the stock astronomer names wrap on the 130p, I decided to get creative. I used a great moon wall sticker just £6 from Ikea (https://www.ikea.com/gb/en/p/kinnared-decoration-stickers-moon-00448463/) as well as some matt vinyl stickers from Redbubble, one for each Apollo mission patch. Below is pics of the mod in progress and the end result - would love to hear what you think!
  3. Hi, Here's a quick shot of last night's moon. I've broken the crayford on my SkyWatcher 130pds so had to hold the focuser tube to get it sharp. Not ideal but I'm pleased with the result. Àny ideas how I can add more colour without affecting the detail? Thanks
  4. 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,
  5. Hi. Its been 12 days of lockdown here in New Delhi, India. Gave me some quality time to spend on my childhood hobby. After a long time, I pointed my 10" Dob towards the Moon. And surely it does not disappoint. Its always a pleasure observing its surface. Observing it through eyepiece was a hair raising experience as I moved from 25mm (48x) to 6mm with a 2x Barlow (400x). Later I connected my dslr to the scope and took some quick pictures attached below. Also took a video. Here's a link to my google drive. Please excuse me for the background noise that is there in the video. https://drive.google.com/open?id=1XzKDibKV_krsYeOaQGgCwuPfFCxaJu55 MOON SURFACE - Ultra Close up.mp4
  6. Hello! What with all this locking down business and home schooling my ten year old son, I have dusted off my TAL-1 and created a slightly less than ideal setup in his room. The westward facing window has been providing great views of the moon and venus over the past week. Obviously doing this indoors is not great (the floor is pretty solid, as is the TAL stand!) but it does mean we get to use the scope every evening, rather than going through the process of carrying the whole rig outside every day. I have a T-mount converter for my old-ish Pentax k-M DSLR, but have quite disappointing results with the camera, when compared to the observed image using the eye. The eyeball view is nothing less than banging - crystal clear detail with a 25mm eyepiece, strong contrast - it's spectacular. I add the camera with an eyepiece inside a tube, and can't replicate the same result, or anything like it. It's OK, but not good enough. I've cleaned the eyepiece today and collimated the scope. The primary mirror looks fine other than a couple of tiny dust particles, no scratches or weirdness on the coating. The camera is working pretty well as far as I can tell. Apart from a little clumsy-ness with the adjustments, the clarity in the eyepiece suggests it's all working fairly well. Photo attached of best result from last night. My question is: is this a focusing issue or some sort of aberration? Should I expect focusing to be difficult in the camera eyepiece? What's going on?! Does anyone have any other tips I can try to get this working better?
  7. Hello all, This is my first post on SL, so please correct me if I have started this topic in the wrong place. I am also relatively new to astrophotography, so please ignore my naivety! I had some clear skies last week, so decided to do some lunar imaging with my new(ish) ASI224MC. I captured my frames in SharpCap as RAW24 AVI files, stacked in AS!2 and processed in Registax and Photoshop. When i got to sharpening in Photoshop, I noticed a sort of mosaic pattern over the image, which took away from some of the detail, and really ruined the image the more I sharpened. I did a quick search and it turned up with 'debayering'. This is a completely new concept to me and all of my attempts didn't seem to improve the image at all (perhaps I was debayering in the wrong order?). I have attached some images and also my some of my SharpCap settings in case they are of help. COLOUR SPACE: RAW24 CAPTURE ARE: 1304x976 OUTPUT FORMAT: AVI files (*.avi) EXPOSURE: 0.29ms GAIN: 282 Thank you in advance Regards, Josh.
  8. From the album: Lunar

  9. From the album: Celestron Nexstar 8i

    268 frames with the old white Xbox 360 Live Vision cam, Celestron UV/IR Cutoff filter, Bintel ED 2x Barlow with lens removed (used as extension tube). Full 640 x 480, starting to see sensor pixels and don't ya just love that noise in the bottom right hand corner. Possible my last image. As good as it's been, the Xbox 360 webcam is near the end of it's imaging days for me. Not that it has problems, but I've upgraded to something better for the job.

  18. I'm a keen moon observer (and new here), primarily using 15x50 Canon image-stabilized binoculars, but also an old 4-inch 'scope that recently broke. I want to take things to the next level and invest in a 'scope powerful enough to study lunar features as the terminator creeps, including craters, mountain ranges, and perhaps even the lunar X, etc. It would be great to have the option of photography in future if that doesn't hugely change what I should buy, but observing is by far my primary goal here. Any suggestions please? Budget is £1.5k+. Thanks! Jamie
  19. I am considering buying a Skywatcher al/az+eq mount to use in alt az mode for lunar CCD photography. I currently have a celestron 11 CDC and a celestron 8 on a nexstar evo mount. I can use both these telescopes with the celestron 'solar system align' and sharp cap for short (~10 sec 300-500 frame) captures. I want to replace the nexstar evo mount for the C8 with a sturdier Skywatcher AZ-EQ 5GT mount BUT - 1) the altz/az option is supposed to be 'for visual use'. Does this mean its tracking in lunar rate/alt-az mode is very poor ? 2) I am confused about 'alignment' (is this only necessary to accurately access the database of interesting object positions?) The skywatcher mount does not have solar system align - but it does have lunar rate tracking in alt-az mode. If I align on any random stars in lunar rate+alt-az mode with the moon centred in the telscope will the mount then track the moon? If not ,is there another way to track the moon ?
  20. Further processing of lunar data captured on the exceptional night of 25th February. Image shows the Mare Imbrium area, taken with my ZWO ASI 120 MC camera attached to my Celestron Omni 120mm f8.3 'frac. Processed through Registax, and edited a little in PS.
  21. Ok...bit of an odd one here...so whilst looking for targets the other night, I stumbled across this object. Now I had got the camera rotated on this one, so it just jumped out at me....hey that looks like the silhouette of a dinosaur (I thought). Now Im not sure this is actually in the lunar 100 (as we have things like the Lunar X and Lunar V...so how about the lunar dino. ;-) Ayway another feature on show in this image is actually very small (and towards the top left centre of the image). It s the Volcanic shield dome (Darney C3). It s roughly 7.5 miles square, but shows as slight 'lump' in the surface. All these images were the last ones taken with my Edge800HD and AVX combo...which is now on its way to its new home. As always, thanks for looking!
  22. So first run out with a new Astronomik ProPlanet 742 filter on my ZWO ASI120MM - this in an attempt to help with a lot of the struggle I've been having with this camera in unfiltered mode. Getting close to full moon so I was shooting for features near the eastern limb - and was impressed with the improvement this filter offered. All the following shots through an Orion SPX350, with ZWO ASI120MM, Astronomik IR-742 filter and a Meade Series 4000 2x Barlow (so pixel scale is somewhere around 0.24"/pixel). Thanks for looking!
  23. Well here it is. Am almost too embarassed to put it up but I won't learn anything if I don't I suppose. The original images were captured on a 2MP web cam using SnapCap. The 1000 frame avi was then processed in Registax using best 85%. Finished off in Photoshop. Be gentle with me guys.
