  1. Hi everyone, I've started working on a basic console application (.NET core) that I can run when guiding that sends me a notification via Slack to alert me to star loss events from PHD2. I'm aware some products like Sequence Generator Pro have notification capabilities already but thought it would be fun to have a go at making something myself. Has anyone else developed software or performed any cool automation to help with their astrophotography? It would be great to see what others have made! Cheers
  2. Hi everyone, Here is the Eastern Veil Nebula (NGC 6992/5), part of a large supernova remnant found in the constellation of Cygnus. You are looking at the wispy leftovers of a star 20 times more massive than our sun which exploded some 8000 years ago. Equipment: - Sky-Watcher 200PDS telescope - HEQ5 Pro mount - ZWO ASI1600MM camera for capture - ZWO filter wheel, Ha and Oiii filters - ZWO 120MM camera for autoguiding - ZWO finder-guider guidescope - Artesky flats box Acquisition: - 6th September 2019 from my garden in Glasgow, Scotland. - 50x120sec with Ha filter, unity gain - 50x120sec with Oiii filter, unity gain - 20 flats each filter and 20 darks - Controlled using Sequence Generator Pro Processing: - Stacked in Deep Sky Stacker - PixInsight dynamic crop, dynamic background extraction, pixelmath (to produce bicolour HOO image), colour calibration, SCNR, histogram transformation, curved transformation, star mask and star reduction, TGV denoise - Final denoise with Topaz Denoise and some touch ups in Lightroom. Future improvements: - More time on the target (less clouds). - Addition of comma corrector to my imaging train. - Create mosaic of the wider Veil nebula area. - Improve PixInsight processing workflow.

  3. Hi everyone, I'm having real trouble processing my Saturn data. Being based in Glasgow, most of my problems are likely due to the poor seeing and how low Saturn is in the sky. However, I still feel I should be able to draw more detail out the Cassini division, reduce the noise and reveal the coloured bands a bit better. I've stacked some 2min vids in Autostakkert and have attached the best stack below (I've included sharpened and unsharpened - which one should be used in Registax??). I've also attached my best attempt at processing this data so far. Is anyone able to have a go at improving on the below or share their own workflows/tutorials? Any help would be much appreciated! Equipment: ASI290MC, 2x barlow, SW 200PDS, HEQ5Pro Sat_033911_pipp_g6_ap9.tif Sat_033911_pipp_g6_ap9_conv.tif Sat_033911_pipp_g6_ap9_conv.tif
  4. Would the below light box be suitable for taking flats with the 200PDS? HUION A3 Size Super Bright LED Tracing Light Box with Adjustable Brightness Function https://www.amazon.co.uk/dp/B00DNPCZVG/ref=cm_sw_r_cp_apa_i_iPs0Cb2DAZ8H9
  5. Thanks, that's great! I've long detached the imaging train since imaging the above targets but hopefully by achieving focus again and retaking the flats I might be able to salvage the Lum data a bit
  6. Good to hear that someone else is having a similar issue (in Glasgow too haha). All comments so far seem to suggest poor flats so think that'll be the first thing I try and sort before trying a clean of filters and chamber window. Does anyone have any examples of a good master flat taken with the 1600mm they just so I can see how it appears?
  7. Also, it looks like some of the circles line up between the lum and blue subs so it doesn't look to be dust on the filters. Perhaps it is dust on the cover of the ASI1600mm sensor cover?
  8. Thanks for this! Before I even think about cleaning the filters I think I'll really need to study flats more as I've clearly not done them right at all 1. Didn't know about using 32 bit flats, I will keep this in mind 2. I did use the flats wizard in Sequence Generator Pro but I must have had the mean ADU value set faaaaar to low! I took 40 flats with each filter 3. I'm pretty certain I used the same filter (all controllled by SGP) and kept the focuser locked. Sounds to me like the exosure time and ADUs for the flats was my biggest issue, especially seeing as there is no evidence of dust shadows on the master flat. I think I may invest in a light box/panel so I can take flats asap after the lights and will have a play with SGPs flats wizard in the daytime and see if I can produce a master flat which is showing up dust.
  9. I've attached my master flat TIF and also a jpg of the lum master flat stretched with STF in Pixinsight. Just appears to be very grainy which doesn't seem right ? MasterFlat_ISO0.tif
  10. @vlaiv Yes, I took flats with each filter using the white tshirt method at dawn and also dark flats. I can't leave my scope out overnight so I took it off the mount but kept the camera attached. I was hoping this would be good enough but from what I've read it's best to take the flats immediately after the lights for them to have any real effect. @david_taurus83 Hmm, sounds like i'll need to give the filters a good clean ? What do you recommend for cleaning them? I was always hesitant to wipe them with anything in case I scratched them but at the moment my lum subs are practically unusable so I think I'll have to!
  11. Hi all, I'm a newbie to mono imaging and am having trouble with circular/ring shapes in my subs. The circles are particularly pronounced after stacking my Lum subs but also appear in blue stacks. At the moment, this is making my lum subs unusable and I'm only just managing to put together RGB images. I'm using an ZWO ASI1600mm with ZWO filter wheel and filters (36mm unmounted). The attached TIF (LumStack.TIF) is 10x150sec of Lum subs stacked in DSS. The circles aren't very pronounced at this stage but after DBE and STF (see second SunflowerLum.jpg) the circles are very clear to see. I've also attached a stack of Lum data on Bode's galaxy which shows the same issue. Does anyone have any ideas what could be causing these? Thanks in advance LumStack.TIF
  12. Hi all, I'm finally taking the leap into guiding and am looking for guidescope recommendations. I have a SW 200PDS, HEQ5Pro mount and an EOS1200d for imaging. I also have an ASI290MC which I've been using for planetary. I purchased an adapter to attach my ASI290MC to the SW's 9x50 finder but the threads are a nightmare and I'm struggling to focus. I'm conscious of overloading the mount so something lightweight which doubles as a finderscope which I can just attach my ASI290MC to would be ideal. Does anyone have any suggestions for this rig? If so, would I need anything else like dovetails etc. Thanks in advance
  13. First attempt at imaging mars. Pleased to have captured some details considering the ongoing dust storm. One very dusty marble at the moment! Equipment: SW 200PDS, HEQ5 Pro, ASI290MC + IR-cut filter.
  14. Hey everyone, Previously tried Jupiter with EOS1200d but was disappointed with what little detail I could get. Decided to get an ASI290MC and wow, was blown away! First two images below were with 2x barlow and, by pure luck, include Europa transit and the great red spot. Third image is prime/no barlow with Io to the left. For comparison, the last image was my first attempt at Jupiter just 2 weeks before. What a difference having the right tools for the job makes! Equipment: SW 200PDS, HEQ5 Pro, ASI290MC + IR-cut filter. Process: 90sec vids with Firecapture, PIPP, stacked and debayered with AutoStakkert, wavelets in Registax. Still loads to learn but very happy with my first attempts. Now to try Saturn....
  15. Thanks for the processing and detailed steps, much appreciated! That is interesting about the horizontal banding! I am indeed using a Canon(EOS1200d). I will certainly take a look at those plugins and books too! Have only viewed all the above processing attempts on my phone so far, can't wait to flick through them om the laptop and compare. Really is a stunning galaxy! Thanks everyone
  16. Wow, thank you so much Adreneline! This was my first ever galaxy shot and for that reason I think it will always be my favourite now! I'll need to take a note of those steps and try recreate for practice. Glad that my focussing is okay as i'm still just focussing by zooming in on a star (Arcturus on that night). Hopefully get a bahtinov sorted soon.
  17. Hi everyone, This is the 2nd ever DSO I have captured (the first being Pleaides). I have very limited experience processing images after stacking. I have attached some of my efforts to draw detail out of M51. There is only around 30mins of data in the TIF file (30x60sec @ ISO800, Skywatcher 200DPS), 10 darks and 10 bias. This is all I could capture before the clouds rolled in. I have tried following some youtube tutorials but am struggling to get rid of the grey-ish tinge to the image and reduce the noise. There also seems to be a dark horizontal band across the image which I think might be a stacking artifact ? I am using Photoshop and have mainly been adjusting levels and curves but not quite sure where to go next. If anyone could give some advice on processing M51, what processing steps they normally take etc.....or even have a quick go at processing it that would be amazing. Thanks in advance Autosave001.tif
  18. Thought I'd provide a follow up on this one. Thanks to your advice above, I managed to track down M51 last night. My star alignment was poor first time around (thought I had aligned to Arcturus but it was a nearby star...don't ask haha) but with all sky plate solver I was able to figure this out early and redo my alignment! Only managed around 30x60sec subs before the clouds rolled in but was just so glad to see the whirlpool pop up on BackyardEOS! Had a quick play at processing today. Need to study more processing tutorials but chuffed with what I managed to pull out from such little data Thanks again!
  19. Ahh thank you, much appreciated.Looks like they tools could come in handy. So I was on the wrong side of Ursa Major, jeees! Learning curve indeed. At least I captured something
  20. Hi all, Novice here, 2nd attempt at imaging DSO. Aimed to capture M51 last night but think I might have been off target. I thought my polar and synscan alignment was pretty good and synscan seemed to be on target for other objects. Can anyone tell me if I was off target or just didn't get enough data? I have tried matching the surrounding stars to other images of the area but can't seem to figure it out. I have attached the .tif output from DSS. I have played with levels and curves but can't reveal anything yet. If it's bad news, can anyone at least identify the faint fuzzy for me? Thanks in advance Details: Skywatcher 200PDS + HEQ5Pro mount Lights 60x60sec ISO 800 10 darks, 10 bias Autosave.tif
  21. Thanks for the pointers Olly! I was certainly battling haze and low cloud towards the end. Glad my focus was okay though as I haven't got a bahtinov yet so just zooming on stars to focus. I had used a laser collimator at the end of my last session but as i'm having to dismantle and reassemble my set up each time, there's every chance I could have knocked it. Also didn't have time to setup laptop for BackyardEOS so was touching the camera to shoot (albeit with a 10sec timer). I'm looking forward to attempting my first galaxy. Do you have any recommendations for a first target? Andromeda is obscured by trees for me at the moment. Andy
  22. Hi, First post on SGL so hello everyone and thanks for all your posts. They have helped me greatly to hit the ground running with my new hobby! This is my first ever DS image taken on 4th night out with my scope. I spent the first 3 sessions practising setting up, polar aligning and imaging moon etc. Last night I nearly never ventured out because of the moon and cloudy forecast but so glad I did! When aligning my finderscope I stumbled upon M45 and decided to give it a bash. Managed around 40subs before clouds rolled in and moon came up but very chuffed with my first result! Criticisms and advice more than welcome Image + Processing: M45 Pleiades 01/04/18, from back garden in southside of Glasgow ~40 x 30sec subs 10 Darks DSS + Photoshop (Messed with curves, levels and used Gradient Xterminator) Equipment: Skywatcher 200PDS HEQ5Pro mount CanonEOS1200d
