Hey everyone, Over the past few days i've been gathering data on M31 due to the battery not lasting long and andomeda dissapearing behind a tree, therefore the mulitple imaging sessions. So far i've been out and me being me, only took dark, bias and light frames for the first 2 sessions but for the last one i also included flats... (The lights all have very slightly different settings cause i have been experimenting slightly... that being 45sec @ ISO 400, 45sec @ ISO 200 and 50sec @ ISO 100) Now DSS assinged all the correct bias and dark frames to the corresponding light frames but becaus -
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'm trying to stack 240 light frames of Milky Way taken from quite a light polluted area. I tried to stack them in DSS. The Milky Way seems to have been stacked okay, but the surrounding stars look like they've been deliberately dimmed or brushed over. I thought there was something wrong with my frames but when I used the same frames in Sequator, it's working fine. I've attached both the images below, and I have exaggerated them a lot on Lightroom just to see how much details I could pull out. Sequator one seems to have too many weird light bands(?) but I think I can fix them using -

Hey all, I took some really rough images of M42 the other night, alignment and focus was by eye, heavily light polluted, no calibration frames and I have a dusty corrector plate. However, this was the first time I have shot a deep sky object and for how rough it was I was pleased, see attached. I watched a lot of DSS tutorial videos last night and I decided to stack the 16 images I have just to see what I get. Now, I am under no delusions as to the expected quality of the final image however, stacking made all the stars vanish and the overall quality of the image was less that that o -
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, 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!

Hi, I would really appreciate some feedback/advice on the following. A few nights ago I took 45 x 300s subs of the Rosette Nebula at ISO800 with a modded 700d Canon DSLR through a Altair Wave ED80. I've stacked the image with 30 darks, 30 bias, no flats (I have a plano which, apart from the extreme edges seems to handle any vignetting) and had a go at processing in photoshop. I live between Leeds & Wakefield so skies are very light polluted but tried to reduce the effects by using a Hutech IDAS LP filter. I started image capture about 9pm so the Rosette Nebula was relatively -
Hi All To date I have been using DSS to stack and (dare I say it) to also perform some image processing. The final, resultant TIFF file has been further processed using such applications as PaintShop Pro, GIMP or even Windows Photo Gallery. I have read that DSS is good for stacking but, ideally, should not be used for any processing. I have downloaded a trial version of StarTools but am having a few issues getting to grips with it or getting any results that are anywhere near as good as those so far obtained with just DSS, PSP etc. I appreciate that learning how to use StarTools will

I've just been trying to stack a series of lights, darks, flats and bias frames in Deep Sky Stacker. The lights, darks and flats were all taken on the same night. The bias frames are older, but have been used on many pictures before (with no issues). However, on this occasion when I ran the whole lot through Deep Sky Stacker the whole left hand side of the resulting image was faded and blurred. A process of elimination narrowed it down to a problem with the bias frames. I took a fresh set of bias frames, but got exactly the same problem. Has anyone any idea what the problem migh -
Hi all! It's been a while since I wrote here, also because this year I've been less active in the field, unfortunately... Anyway, I've now started to do autoguiding, with mixed results. I bought myself a laptop and guidescope, with CCD. I'm able to do 10 minute exposures that come out fairly well most of the time. Guiding is mostly good. I tried PHD as well as Maxim, but lately Maxim seems to be doing better, or I just found the sweet spot for my setup. The last 2 or 3 times however, I'm having difficulty in obtaining decent images. Even with no moon, the images I get are q

I've recently started DSO imaging: Canon EOS 550D (modded), Celestron 9.25 SCT, AVX mount. I use BYE, save RAW + JPEG to laptop, then process in DSS. When I go into Register checked images: advanced: compute number of detected stars; I get a decent number (approx 250) if I am registering JPEG images at 2%, but very few, often zero, with RAW images of the same object, no matter where I put the slider. Am I getting the settings wrong, or is there another answer. Thank you.

Hi! I have about 4 hours worth of data from M51. I captured my subframes with my 8" Orion Newtonian Astrograph and my Nikon D3200. About two hours of data are from 30 second exposures (some at ISO800 and others at ISO100). The rest are 4 minute exposures at ISO800 (these were captured after I bought my Orion Starshoot SSAG). In order for DSS to align these frames, I need to have different star detection thresholds for the 30 second subs and the 4minute subs. I tried doing this by using batch Stacking, but it still uses the same detection threshold for all the file lists (or so I think, si -
Hi! I did an imaging run on the Flame/Horsehead Nebulae last night, and I got about 2 hours of data. About 20 minutes worth are with my hydrogen alpha filter. To my dismay, when I went in to stack my subframes on DSS, I get a message saying that only one out of my 52 frames will be stacked. I've been tinkering with the settings today, but I'm not sure if the problem lies with my DSS settings or with the frames. These were the first i've taken at ISO 800, so I'm worried that my stars may be a little too big/burnt out for DSS to actually recognize them as stars. Perhaps I haven't focused we

As in the title, I have a set of 11 Lights plus 16 Darks loaded into DSS but it says it can only use one of the lights. Individually, they all look much the same if rather dim. There are lots of things that can be changed but it's 2 years since I last used DSS and I can't remember what to do. Any help much appreciated. Thanks

Hi I've taken a few images from a dark sky location of the night sky with just my Cannon camera on a fixed tripod - 1 minute frames (25 mins total). I realise these are short frames, but as I didn't have a mount with me I though 1 minute would be OK before stars started to trail. Anyway, when I try stacking the frames through DSS the images stack but show the same star multiple times as they rotate (we rotate) in the sky above. When I check stars chosen for alignment these are actually hot pixels, and I can only see one or maybe two that are actually stars. I've tried pick

I see this question appears fairly regularly so I have been reading through a lot of old threads before posting however none seem to answer my question directly, hence this post. I have been using DSS for a while now and in general I have been stacking and then choosing ‘Do not apply adjustments’ and saving as a TIFF format. I suspect these steps are detrimental to the outputted file in that precious data is being lost. From what I have read I should always use the ‘Autosave’ file and save as a FIT file (32bit?)? Then go into FITS Liberator and save as a 32Bit TIFF or 16Bit Tiff? -
I am having lots of trouble processing some widefield Milky Way shots in DSS. At the end of the stacking process I get the usual screen for R G B wlignment but the image is white/blank without any RGB curves. I am using a canon 100D and the latests versions of DSS. Has anyone encountered this problem before? I have run out of ideas as to how to solve it. Thank you all for your help.

Hi, I have taken mono LRGB images of M51 with my new ASI1600mm-PRO. I have a mix of 30s, 60s, 120s subs. 100 darks, and 100 flats for each filter. About 4 hours total. I Used DSS for alignment and stacking, then Pixinsight for LRGB combination. My issue is that i'm not happy with the colours, the stars all appear white and the background is strange. I have attached the Aligned LRGB images. Can anyone point me in the right direction? Thanks! Green.TIF red.TIF Lum.TIF B.TIF- 18 replies

I had a successful session the night before last - my first with guiding using the ASi120MM on my ST80, atop my ED80 through which I imaged with my unmodified Canon 1100D and focal reducer. I was pleased with this image using 13 x 300 second lights with darks and flat frames: Then last night I thought I would try M51 and things have not gone so well. However I only took 6 x 400 second lights, 3 darks and used the previous flats as still ISO800. This was my first image out of DSS with a star detection of 50 stars: There appears to be a distinct lack of colour, I did moved the right hand RGB/K -
Hey SGL I was wondering in what order to processes DSO, and if different types of DSO require a different order. This is still basic, so 1 set of lights, single shots (aka not using filters to split colours), etc. Tutorials suggest: eg BudgetAstro DSS Align Colours Remove Vignetting (PS if no flats taken) Star Mask Levels Curves Match Colour / Reduce Noise / Sharpen I notice before I watched the BudgetAstro videos, my pictures turned out to be more vivid, when is Saturation done?
