  2. I found that the new version of Autostakkert is now available as a beta download. AS!3 here Peter
  3. Hi I took my first Solar avi's today with a PST and QHY5-II. They were not that good due to intermittent cloud, but I managed a few runs of 1000 to 2000 frames. I have been trying to process them but both Registax and AS2 are falling over during processing. AS2 runs through quite quickly but just hangs at the MAP Recombination stage. The Stack button rehighlights and the system is idle but no file is produced. Registax takes for ever but hangs after the Limit stage. I am running Windows 7 on an i3 laptop. Any ideas? Is it something I am doing or could it be a quality issue with the video. Thanks Barry
  4. Hi I have recently purchased a ZWO ASI120MC-S webcam from FLO. I wanted to try it the other night so I decided to get some test images for the moon. I was using Sharpcap for this. I manged to get the video and was using Autostakkert to stack it. On the final stacked image I can see that there are some strange vertical lines. I have attached a picture of that. There is also a zoomed in image of a region and I can see some small squares almost resembling the pixels on the sensor. Below are my capture settings as given by SharpCap. [ZWO ASI120MC-S] Debayer Preview=On Pan=0 Tilt=0 Output Format=AVI files (*.avi) Binning=1 Capture Area=1280x960 Colour Space=RAW8 Temperature=19.2 High Speed Mode=Off Overclock=0 Turbo USB=86(Auto) Flip=Both Frame Rate Limit=60 fps Gain=50(Auto) Exposure=0.001993 Timestamp Frames=Off White Bal (B)=95 White Bal (R)=52 Brightness=0 Auto Exp Max Gain=50 Auto Exp Max Exp M S=30000 Auto Exp Target Brightness=100 Mono Bin=Off Apply Flat=None Subtract Dark=None #Black Point Display Black Point=0 #MidTone Point Display MidTone Point=0.5 #White Point Display White Point=1 TimeStamp=2018-06-25T23:13:22.6772909Z SharpCapVersion=3.1.5214.0 For Autostakkert (v2.6.8 ) I was not doing anything fancy. Pressed analyze and then used 50% of the frames to stack. Used 200 as the AP size. Also, had the drizzle as 1.5x My camera was mounted to a skywatcher 200pds and HEQ5 mount. I am failing to understand what is going wrong here. Is the camera a problem or stacking is an issue ? Please let me know if there is any more information that you need.

  5. What are the two axes on the quality graph in AS!2, and what does the length of the grey lines represent?
  6. Hi all. I'm using Firecapture to image Jupiter with ASI290MM with an EFW and something odd is going on with my red histos. I set all channels to the same exposure and gain - I realise this isnt neccesarily the best way, but for now thats what I do As I do the captures, typically 4 runs of 120secs per colour, the histo looks consistent - about 66% for R and G and about 55% for blue. But when I l look at the log files, the reported max and average histo values for the red captures are OK on the first capture, but greatly reduced on all the subsequent red ones. The G and B histos are consistent throughout. So for example last night I did 6 runs, for the red max/average histos I got: 1. 162/63% 2. 97/38% 3. 107/41% 4. 112/43% 5. 101/39% 6. 103/40% I watched the histo carefully on the last run and it didnt dip below 60%. So how can this happen??? I'd be really gratefull for any answeres! One other unrelated - I think - issue, is that on subsequent runs, because I dont have a delay set, I catch the filter as it switches in at the beginning of the run - except on the first run of course. Hmmmm as I type this I'm just cross checking with the unsorted AVI files in AS!2 and I see that not only am I getting a few chopped up frames as the filter switches in, but also neearly 100 of the previous run. So at the beginning of my 2nd red run I have about 100 blue images (approx 110 fps) Clearly I could sort this by having a delay. But right now I have 2 issues: 1. Is the reported histo value affected by the carry over of frames from the previous colour run? 2. Crucially, the AS!2 sorted AVI has included at the beginning some dodgy frames at the beginning, ie deemed to be good quality, which are from the previous colour, and also some with half a frame from the filter switch which for some reason arent rejected. So - how do I delete individual frames from the sorted file??? I cant see any way to do this. Alternatively, can I delete them in PIPP which I run everything thought first? Or maybe PIPP has a setting to reject dodgy frames with mismatched data or half frames.? Sorry people - lots of questions!! Would really appreciate any help, especially as Jupiter is about to exit, stage right!!
  7. I have just purchased a ZWO ASI120 and started to image the sun with my Lunt Solar 60. but I ma having problems with stacking the outputted Avi files. In registax the file loads up, the image is seen and it starts the stacking process but once you hit the stack it just goes blank. In autostakkert it wont even load. The problem is with large files 2 and 4 gb. I have compressed and registax seems to work. But autotakkert wont take the compressed file either. The strange thing is last month I took another AVI which is 3.3 Gb and autstakkert takes it no problem. Another odd thing. If I take a film with Sony a7s and convert it to Avi neither programme will stack it. Any advice?
