Usually the problem with flats, if they are calibrated correctly- is an equipment/acquisition issue. Generating good flats is hard. Usually people that have corrector lenses or focal reducers are in trouble. Also in your case, the edge of the frame …

Thomas, You can follow examples in the workflow section (like NGC 3486 for example).Yes, your steps above are generally correct. The L can C need to be stretched before doing the LRGB combine. I would not do LRGB for FastTrack Training. That is too…

The calibrated subframe is beautiful.Please check the registered frames and verify they are *all* aligned with respect to one another in Ha. (Use Blink). It appears to me something has gone wrong.... either with Normalization or as part of Image Int…

It is a good idea to use a browser (I believe Chrome has this) that will resume the download if interruptions occur. -the Blockhead

There is some confusion going on here. This is the kind of thing where a video showing what you are doing would be helpful. I suspect you might be getting tripped up on whether the STF is updated or not... but I really can't say without seeing what …

HI Darren, You are being a little unfair. :)I literally have a section that discusses this:https://www.adamblockstudios.com/articles/wbpp-master-files-wbpp (near the end of the video) So yes, you can produce master calibration files only. Just load …

Nelson, What you are showing are not process icons. You are shading processes on your desktop. You can arrange process icons. To create one, drag the triangle from one of your processes to the desktop. This would be a process icon that can be arrang…

In pixel math, when you divide one image by the other- you might need to check the rescale option so that you don't end up clipping values that go above "1" (it depends on which image is the numerator).-the Blockhead

Simple answer... none that I can recall. Use the method that gives the best results... :)-the Blockhead

oh... you mean translucent material for 4 and 5... (not opaque!)So... in that case maybe the situation is better!But... compare with twilight flat for a sanity check.-the Blockhead

You can see from the flat that the paper is probably not a uniform scatterer. I do think the paper is an issue. Maybe it isn't the paper... but the flat doesn't look right to me. In addition, I am not a fan of flat boxed fitted tot he front of a tel…

These stars are out-of-focus...and will not be detected by PSF fitting algorithms. This is certainly part of the problem. Under Star Detection I think you can force the "Compute PSFs" to never. This *might* help.. but focused stars probably the best…

Indeed! Good news.-the Blockhead

Hi Todd, The best thing to do is reinstall the program. Not having thesame thing int eh dropdowns is a sign of an incomplete installation. Thanks,-the Blockhead

Yes, a I think another update video on NSG is probably a good thing. I can answer the integration question. Obviously Local Normalization needs to be set. NSG no longer calculates the weight internally. That is because the weight calculation for PSF…

*IF* you create an LRGBHa image... you *always* create an LBlend(Ha)Rblend(Ha)GB image. Otherwise, you will not color the Ha that is in the L...and it looks goofy. Whether or not you do RBlend(Ha)GB or LBlend(Ha)RBlend(Ha)GB depends on the data. Us…

The basic idea behind using Ha (or any narrowband image) is that doing so makes light from the sky dark. This means the image of the nebula can be shown with much greater contrast. When a picture is taken of the Lagoon nebula there is little differe…

I use a Logitech wireless mouse under WIndows.I guess I never gave it much thought concerning the shading versus iconization. Seeing an image preview certainly could be useful. The main thing I try to do is keep the number of active/working images I…

Hi Dean, I am not certain there are many good cases for using Ha as a luminance image. The idea behind a luminance image is that it has strong signal which allows for separate processing and later blending with color information. You mention using H…

Great... sometimes it is tough to analyze what is going on "blindly"... I am glad this worked out.-the Blockhead
