The way my SUPERBIASMaster looks as a jpg and three single-same images of M104 for 107secISO6400 'calibrated' and one is not 'calibrated' . The M104 images were all 'Equalize-Stretch' to one of the images . CanonEOSII RebelT7i modified UV-IR @ Hutech and using MaximDL Pro V6.16 for 2124 'bias' frames thru the Autosave Sequence and doing with one battery charge for 354 'bias' frames at a time and then changing the battery in the RebelT7i for another 354 'bias' frames which took 3 1/2 hours each and two different days till I had done 354 'bias' frame six times for 2124 'bias' frames .... and they had a 'Std-Dev' of 59.xxxx and I used ' 60 ' and that number times three is ' 180 ' and in the "Set Calibration" I use ' 200 ' for the 'Pedestal' . I put all ' 2124 ' 'bias' frames in and I Average combined them which took ' 27min. ' . { This JPG is the FITS image looked at in MaximDL Pro and at a 'Range' 'screen-stretch' and at Bin2 and then Bin2 but it looks very similar to the Bin1 original . } . The idea here with ISO6400 and an extreme amount of 'bias' frames used is to imitate or actually create a SUPERBIASMaster hoping for a complete removal of the 'bias' in a 'light' frame whether it's a CR2. or a RAWMonochrome FITS . I tried it on a RAWMono single of M104 107secISO6400 and compared it with the same image that wasn't 'calibrated' and there seems to be a little bit of a difference . When MaximDL Pro V6.16 'opens' and you check the "Settings" page for 'Files' and always the radio button in the 'When opening 16-bit images with negative numbers:' section .. 'Treat data as unsigned' is always active , and there is the option 'Add offset to make positive' which to use it you select it and then press 'Apply' and then 'OK' . Leaving the program 'open' it will stay active and I think it has a little different result because it would realize 'positive and negative' numbers in a file and use the smallest interger and cause the data to be 'positive' in that way .... then when you 'Calibrate' with a BIASMaster it's possible the statistics have different data to remove the 'BIAS' from the image . It might be the best way but I don't know if you were using the "BatchProcess" with 'Calibrate' in it and the 'open' image is using the radio button for 'Add offset to make positive' ..?? . I did this many 'bias' frames for ISO6400 because I can use them on the Baader 7nm Ha filter images and other filter images and the 'bias' frames were not 'compressed' ...but when I do the other ISO 'bias' frames which will only be ' 1024 ' frames each I will use the 'Compress Captured Images' in the "Settings" 'File' page for less disk space ... after I'm finished with them I'l move them to a Toshiba 2-Tetrabyte drive for storage as 'compressed' also . [ This idea is from a webpage I saw about a Nikon DSLR and 'Pixinsight' use for a SUPERBias that is ' 250 ' 'bias' frames and a proceedure to imitae several hundred 'bias' frames as a SUPERBIASMaster so I used as many as I could for mine .... I don't have Pixinsight to use .] . Another option I tried that can work on the BIASMaster is ... when you 'open' it into MaximDL Pro and use the 'screen-stretch' to show content instead of the 'Medium' stretch .... I tried the "KernalFilter-Median3x3" and the BIASMaster will smooth a little and the 'hot' or 'stuck' pixels will be removed and you do a "Save As.." with 'Smooth' added to the extention .... then over that affect I did a "KernalFilter-Average3X3" and that was 'Smoother' and saved that way .... now there are three different choices that can be used for the same ISO BIASMaster 'calibrate' .!. Also , the webpage that talks about ' how to take bias frames with a DSLR ' has other 'Tips' and I searched there for ' dark frames ' and a page came up that has some info on 'dark-frames' but it says they aren't used because with a DSLR it is temperature sensitive and if things aren't right the 'darkMaster' will put 'dark-current' into an image instead ... but , a 'cooled' camera would be able to use a 'DARKMaster' if the temperature is always the same ... , so only a 'BIASMaster' is needed and 'a 'FLATMaster' if vignetting exists .... so the main idea is to "SUPERBIASMaster" instead .... I am always using with the CanonEOSII RebelT7i 'High ISO Noise Reduction-HIGH' so this might be removing some 'dark-current' but the extreme SUPERBIASMaster might be helping with the 'sensor' active electronics that get recorded into an image and the 'read-noise' also . .x \\\\\\ Also , on the ASUS site for this laptop they say you type into the laptop's 'Search' area ' Task Manager ' and there is an App which brings up the ' Task Manager ' page and you tap on the ' Performance ' tab and then the ' CPU ' type icon and the page changes and you can see the 'CPU' usage and also there is a word - ' Core(s) ' and it will show how many Cores are in the laptop and this one has ' 1 ' Core and is an ' i5 ' Intel , and I looked in the ' Device Manager ' and for ' Processors ' there are ' four ' different identities so I think that could mean ' four ' .. ' threads ' ..... , so , in MaximDL Pro V6.16 for the "Camera Control" 'Options' there is a 'checkbox' you want to check so the camera uses it's own ' thread ' and doesn't mix with other things going on in the ' Core ' 'Processor' ./////. x
