You are combining two different things. SPCC is designed to calibrate the ratio of fluxes (intensity of light) of the wavelengths you observe based on your filters. So when you observe with a RED filter of a given bandwidth and transmission- the ca…

You need to download the latest version of PixInsight from your account. In addition, you need to check you repositories (after getting the latest version) and make certain they only refer to 1.8.9-1 . -the Blockhead

Ok.So I found out.The camera manufacturers do not publish different curves for the sensor and filters. They publish (if at all) ONE curve. We are to assume this ONE curve contains the full information. Thus we only select the filters and DO NOT choo…

When I tried without specifying the sensor- the results of the plots looked terrible. Looks fine if included... so, just because someone clearly says something... doesn't mean I listen all the time. I plan on making a third video of errata that the …

This is OK.You can uncheck generate output. Basically running the process to find stars tests to make certain the catalog files are OK. You can actually extract the GAIA numeric data with the GAIA process. But we are just testing. No output required…

I think the CMOS options are pretty much where you should invest your time/energy. They have lower noise levels and this is the area that is advancing quickly. There are now 16-bit CMOS with QE curves that equal or exceed CCD. So..I am not certain w…

The dew shield is asking for trouble if the inner surface is shiny/reflective. These are no good for astrophotography usually. It could be one source of problems with regards to getting good flats. You might consider using black flocking paper if yo…

I don't see anything wrong with the image.You chose to have high contrast for the dark portions. They look almost black. This means there is no difference in the attenuation of light due to the contrast. The nebula is also flat in its overall bright…

Hi Ronald, Concerning the gradients, you image has blue on one side and green on the other. The result of DBE should be pretty flat in terms of the large scale color gradiens.There also appears to be a very low electronic noise. (You might want to m…

Hi Richard, This image is puzzling. First, unfortunately it isn't possible to figure out the puzzle by looking at the integrated image. We would need to examine all of the raw data and their masters to start to figure it out. One thing that bothers …

This looks pretty good to me. It is kind of amazing. New students think they can walk in and take images of LBNxxx. Just 15 years ago this would be absolutely unheard of! :)Since this object is so faint the issues are caused by sky being the same br…

Thanks... Concerning the files... if you just want to list the files of a particular date (within a mixed set of files)you can type *02_19* for example. This will list all of the files from the 19th that you can then select and blink. You can add m…

Yes, I did indicate you should only grab the first four. I will make this clearer on the page. I made the first set available as a bonus (it is good data). Regarding the file naming. People often complain I am an elitist and only work with my own hi…

Hi Steve, I am laying some groundwork here..but I have not started this. I am not certain I will be able to before the end of the year. Please look for an announcement soon (If I do it). As you know, PixInsight and many other "youtubers" are produc…
-
Oooh... not good.This looks electrical.FIrst thing to do do is eliminate any variables. You should attach your USB cable (or whatever it is) directly to the camera and take some images. Do not run through the mount or near any other devices. If you …

Please see my updated videos in FastTrack Training which now show this. -the Blockhead

Thanks... look below the original FastTrack for the work in progress.-the Blockhead

Hi Richard, At the moment I am desperately trying to recreate FastTrack (which everyone should review once I am done) as well as an explainer for SPCC... I am working non-stop this weekend. I probably can't get to this immediately... but that being…
-
LOLI know what you see... we are all on the same page.I am currently making FastTrack Training *AGAIN* from scratch to capture all of the new changes and updates. In addition, I will be explaining SPCC as well. Please look for videos to be published…

HI Van, Based on this image, I agree there is an issue- but you need to widen your scope of consideration. It looks like the signature of a light leak or scattered light. Did you take your dark frames in the dark? What did you use to generate your f…
