Hi Bruce, What you have not shown are your file names (or path).File names and path take precedence over FITS key words. I would wager that "New Data" is in your path statement...and likely there is preceding "Gain" before it??WBPP isn't making a j…

I like it too... just tried it the other day.-the Blockhead

A couple of things. Yes, I do think longer exposures might help if the sky is dark enough. At a certain point there is something of a faint limit that is determined by your sensor/telescope and sky brightness. So certain objects are just not going t…

You need to make certain this isn't an oversubtraction of a bad dark. Verify the numbers make sense.If you are convinced the dark frame is good... you can use the auto pedestal of the WBPP or you can look at the value(s) of a pixel(s) in your raw li…

Hi Helge, Unfortunately you are misinterpreting the results you are getting. In the first image the background is bright. That means there are higher values there. The autostretch routines just work on the histograms of images. They do not know anyt…

Hi Ivor, If you are generating normalizedfiles... you would paint over them after they are written to disk. If you are using local normalization (and not outputting intermediate files)- it is best to do it on the registered (pre-NSG) files. The same…

I think my question is...in your calibrated data (with your new filter)... are there zeros? (especially in the location of the amp glow). This indicates either an oversubtraction (which means something is up with the dark frame) or the pedestal issu…

Hi Nihal, Would you mind reviewing this video?https://www.adamblockstudios.com/articles/step-up-your-narrowband-imagery-pedestal It would seem you need a pedestal. You can check for zeros...and confirm.-the Blockhead

Mark, If you do not want the explanation, just use the MureDenoise detector settings script with 2 raw flats and two bias frames. However, I explain exactly what this means in this video:https://www.adamblockstudios.com/articles/Gain_ReadNoise No o…

Hi Rex, The copying of pixels is agnostic to any blending. You would need to specify a mask on the target frame (as I show in the video) in addition to use of the script. HDRMT is a special case where, with appropriate settings, it matches (or leave…

On my site or YouTube?Is this not correct?:https://ngc2237.ch/pi-scripts/ -the Blockhead

Hi Mike, What does the raw frame look like? Does it show the same thing in the sense of darker in the middle and brighter to the edges? I am going to guess not and this is likely a calibration of the flat issue.You will have to go into details of ho…

Thanks Craig. There is still more to this unfolding story... but I need to create videos on it now- I can't wait for the complete thing to unfold as it will still take weeks or months more (I suspect). I really appreciate you taking the time to watc…

Excellent!Thank you for being a member of AdamBlockStudios!-the Blockhead

Hi Rex, You *can* get the raw data from telescope live (I do). Then when you process the data, Pixinsight will do its new measuring stuff. I do not know what the minimum plan is for this access. -the Blockhead

What you are doing wrong... you just need (wait) to catch up to the future. :)I am a little ahead of you. This is supposed to be a benefit of subscribing to me... sometimes I can provide information that non-members are not privy to. The next releas…

Cameras are not light tight. (no camera, period).I always say that darks should only be taken at night and away from any sources of light. You did certainly discover the issue.-the Blockhead

Hi Reggie, Did you see my video on this? https://www.adamblockstudios.com/articles/pcc-catalog-coverage The first error says explicitly there are no stars in the catalog. This means there is likely a hole in the catalog. So I followed my directions…

I think you need to get out a ruler... it is an optical illusion. lol.I need little lines to run across..but Color Calibration is 7 videos..the 35 refers to Processes.I know..it is hard to follow across and match the numbers.-the Blockhead

Hi Roger, This was the entire point of my presentation! It is hard...I know it was for me, to understand that weighting by PSFSW does not track with SNR like methods is what is INTENDED. It is correct according to PI developers that SNR methods disa…
