Hi... Hope this is ok to post here. I've built an app to create star trail images and videos using an iPad or an iPhone and i'm really struggling to find beta testers. Check out the photo and video I've added to the post to see what it can do and and click the link if you want to try it out. https://sites.google.com/view/starstackerforios-beta/home for info. https://testflight.apple.com/join/7iLGfVDG to get the beta. It's free to have early access to the beta. I'm just hoping to get a bit of feedback before it releases. Many thanks! Star Stacker iOS.mp4 -
I have a huge problem with DSS. About a week ago, I took 300, 2 second long exposures of Andromeda with my skywatcher 90/900. But when DSS started scanning the stars in the images, it only registered about 5 stars at 40%. And only 7 stars at 20%. I tried to stack them and selected stack 100% of frames, but it only stacked around 29. I even tried it at 4% where it registered around 40 stars, but DSS crashed mid process due to the immense amount of stars being scanned (60 000 per image at least). I tried it sooooo many times, but I don't get it to work. It somehow stacked 13 -

I like live stacking as I can see the image develop and it saved my hard drive being cluttered up with thousands of images. The downside, I have found is that if a cheeky wisp of cloud comes over, it often gets included (in spite of trying to clamp down the FWHM settings). Some of my images then have a like a grey smear over them. Then after and hour of live stacking I find it looks just like a greasy smear over the picture- which is a real pain to try and post process out. Always seems to happen when I pop indoors to make a drink etc. I noticed that there was a setting on SharpCa -
This is probably silly, but anyway here it goes.... What would happen if say someone intended to shoot 100 of 60sec subs of orion nebula or Andromeda, and clouds rolled in the middle of the session or just got bored and stopped for a hot beverage. Now this poor fellow is left with only 50 subs and starts thinking of copying and renaming these 50 subs in the same folder (unaltered or with slight denoise or slight Gaussian blur) and stacking all of the 100 subs?

Hi is anyone using Regim to stack using a dslr modded , currently trying to work out the settings in regim , im using a modified canon 1000D , do i need to set up libraw within regim ? if anyone has good success in using regim i would be interested in hearing what settings you are using .

Hi all, first off, still a newbie at imaging and astronomy for that mater. So i'm taking my first steps shooting the moon, with my Skymax 127 and Sony Alpha6300 in prime focus. I also used a moon filter but i guess next time i wont so i can match my shutter speed to my ISO since i've learned that's the way to go. I've shot quiete some pictures in RAW and tried stacking in Lynkeos (Mac over here), following are a single shot and the stacked one (40 shots converted to .png) Does anyone know where the purple/pink is coming from ? I guess one coul

I'm very new and green when it comes to image processing/photographing the night sky. I barely know any of the terms or lingo, but I very much want to get involved! Here's my question: What are flat, dark, and bias frames? How do you create these? Thanks.

So here's a thing - it seems to me that astronomy is one of those not very straight forward hobbies. Last night I though it would just be the same as Friday night - set up, look at the moon take some pictures! Simples... Aw but not to be!! I'm good at setting up in the daylight, get my mount bang level (checked with electronic level app on phone...) Get it facing north with my beautiful brass compass and enter coordinates back to Kidderminster from Thame, then you would think just observe... Nah! Moon very wobbly with tinges of green on the edges... Barlowed it a

Hi there, I am still new to amateur astronomy and astrophotography. I recently took my first steps towards moon and Jupiter photography. While I am satisfied with my moon pictures, I am struggling with Jupiter. I am a bit desperate, so I hope that maybe someone good give me a couple of useful hints so I can learn and improve. When shooting Jupiter without any barlow lense or eyepiece, I manage to get a sharp picture and am actually reasonably satisfied with the results (see attachments named "ok.."). I use Firecapture to shoot something like 3000 single images (mostl -
Well, not really actually. For some reason the stacking process produced this strange image. Most likely the image registration process aligned on hot pixels. And since the camera (Liverpool Telescope) is used in two orientations (90 degrees rotation), this was the result. Two colliding galaxies. Or is that three colliding galaxies? Or four? -
I'm looking for a simple algorithm to compare astronomical images (of the same sky region) against each other, compute their movement and rotation, to finally stack them. At the moment I'm already having a more or less working algorithm. First I extract all the stars out of an image (including information like brightness and FWHM), and then I walk trough all the resulting "points" and create triangles out of the current point and those two other stars that have the shortest distance to this star. This list of triangles is created for every image. After this I take one image as refere -
Hi, Hoping for some help here.. Im trying to learn some basic processing in PixInsight, including the PreProcessing (calibration, registrering, stacking, etc.) Im using the only data I have, from my very first lights of M13, calibrated with a SUPER BIAS, no darks and flats yet. When doing it in DSS I get 7 images stacked and the stacked file looks OK. Switching to PixInsight it goes horribly wrong after stacking, and the stacked picture looks like the attached. I have done the whole process in two different ways, but get the same basic result. 1. Doing -
Hi, can anyone help with star detection in DSS. I have been getting some good images using my Star Discovery 150p and nikon d5100. I'm using a 2xbarlow as I know I can't gain prime focus on this OTA and keeping my exposures down to 25secs due to field rotation with it being a Altazimuth mount and this can also be corrected in processing. The problem I'm having is that when I put everything in to DSS and register the images, it detects hundreds of stars but when I stack them it tells me there's not enough stars and to change the threshold so it can stack more of the images! T

I understand the purpose of shooting dark frames, but what are 'flats' used for? Is there a general ratio of darks and/or flats to process with the collection of images when you stack them?

Hi everyone. I'm currently running Linux on my laptop and just wanted to know the best stacking software is for an amateur to use. I tried installing registax with wine but it didn't work. I've tried out PIPP and didn't really get on with it. So far the only one I've gotten my head around is Siril by free astro. Would like to know what other software there is that works well on linux that is good for amateurs who have just started playing around with this.

I've been putting together a stacking program and today I got all the building blocks working (after a fashion) for the first time. Still lots to do of course (tuning, handling of boundary conditions and testing, testing...), but here's the "first light" (with a touch of unsharp mask):

I did a test using the same stack of images, but using 5 different stack modes in deep sky stacker... which one is best? I just did very minimal adjustments to them and they all have the same....align rgb, and adjust exposure.... this is a stack of 26 min 30 sec........ 106*15 lights, no darks no flats no bias,,,,,,iso=3200 f7.1 on 50 mm lens........... If someone would like to process them and see what you get out of them that would be great....... I cant really see too much of a difference between the different stack modes All of them have the same file size except t -
While playing with manual image stacking using GIMP to see the effect on image noise, it occured to me that a short video showing the noise reduction might be interesting to other beginner imagers. (The % layer opacities might not be quite right.) So it's done and can be seen at :

Hi everyone, the black and white image is an image that I stacked in dss and the other image is a single shot of what I stacked! I was wondering if anyone would take a crack at editing the stacked version of the picture for me as I am trying to get my head around editing and am wondering what a picture like this could look like with a bit of tweaking ? Thanks everyone

Evening All! I'm starting to take my first steps into the 'post-processing' of my images, and to be honest with you, I have no real clue of what I'm doing. Hence why I'm here tonight, to pick your brains This is just one of a large selection of identical images I took tonight of a randomly selected patch of sky: DSC_0532.NEF As you can see, I get a fair number of stars in the image, but it's nothing too spectacular. Exposure time is only 1.3 seconds so I wouldn't expect much too begin with!. Now my main issue is how to stack my images properly. I know that I should stack

What are the two axes on the quality graph in AS!2, and what does the length of the grey lines represent?

Now that imaging season has come to an end, I have the time to do some reprocessing of old data, and I thought I'd share some of my processing methods. I gathered much of that data before I started doing dithering, and the usual background I am fighting looks like this: This is an extreme crop of a wide field image of the area around NGC 1499 (the whole frame covers the area from M45 to Mirfak), taken with my unmodified DSLR. The stars show trailing, but this is not a problem in the final image. Process details: 12 subs, integrated using AVERAGE integration with sigma

Ok, so i had my first run at planetary imaging yesterday evening, which was disappointing to say the least :/ I was trying mars. The setup went smooth, and imaging went ok as well, but the seeing was very bad and especially the heat of the atmosphere was high, which blurred the images to the point that mars' image was not even a sphere (see left image). There are , however, also other probable issues: + Short focal length (800mm) with an 8mm EP, resulting in only medium magnification + problems with focusing the blurred image + missing real astro darkness (24th of june
