Please note: If your image does not have an astrometric solution, SPCC won't work. You can go to Scripts/Image Analysis/ImageSolver and search for your object and then click ok to apply an astrometric solution to your image.

Shouldnt NINA add an astrometric solution to the FITS file if it's solved by ASTAP?

When using DBE, prior to SPCC, make sure you choose "Replace Target Image" to preserve astrometric information. If you don't, the processed image does not preserve this information.

Thanks James. One thing to note... Your image needs to have an astrometric solution before SPCC will work. It may have it if this was checked off in WBPP. But if you have cropped the image at all, then ImageSolver in Pix needs to run on the image to re-apply the astrometric solution.

This video helped me a lot. I am new to Pixinsight, and was not sure how to get SPCC up and running. You saved me a lot of time! Clear Skies!

Extremely helpful as usual. Thanks very much! 👍👍👍

As a point of information, storing the Gaia data in the PixInsight folder in C:\Program Files causes it to be deleted if you upgrade PixInsight. You may want to store the Gaia data elsewhere!

This is cool but I miss the old photometric calibration where one loads the focal length, pixel size, time, and then search for an object such as M31. The new SPCC doesn't work for me. Has the old PCC been retired? Love your videos. You're one of the few guys that doesn't compress 10 minutes of info into a 20 minute video.

As always, many thanks, Shawn. I'm a little late to the party, but nonetheless . . . mui appreciado, which is "New Mexico Speak" for gracias!😁

Thank you Shawn. ⛄️🎄. I know others have asked, but what 'filter' setting should I consider when using OSC with 'no filter' , such as the L-eXtreme, please?

@VisibledarkAstro

Жыл бұрын

It's a good question. For OSC on its own you can select ideal curve and then use a uv/ir filter choice from the drop down. The problem I am seeing is not all the filters are shown. I'm looking into this more. Hopefully I will find an answer.

I’m having a difficult time getting SPCC to work on a narrowband image taken with a OSC camera (ZWO ASI2600MC PRO) using an Optolong l-xtreme filter. Would you be able to give me the appropriate settings or better yet, do a tutorial?

Thanks for this video Shawn. In the filters section, what should I do when using a "One Shot Color" camera (in my case ZWO ASI294MC Pro)? Images were taken without filters. Should I choose the "Sony color sensor R or R-UVIRcut or R-UVcut ?

Should be applied to linear image. Cheers.

The file type provided in the download is XPSD, but what the program wants is XSPD. The former is of no use to the program and isn't even seen by the program. What's the solution?

Hey Shawn, love your videos and always really good info. As a request for teaching people and being clear, you often say "Check OFF background ....." when in fact you want people to select that particular option even though you say "Off". To avoid confusion could you just say "Check" or "Turn on by checking". Thank you

Hi Lynn. So modding makes the dslr transmit like a cooled camera with uv/ir. Use ideal curve and the Canon osc filter. The 5d should be fine.

Shawn, what might you suggest for an OSC with the l-eNhance filter? Would the narrowband clickbox be appropriate?

@VisibledarkAstro

Жыл бұрын

Hi Steve - yes use the narrowband checkbox. Here's a video demonstrating this... kzread.info/dash/bejne/n4mYlqZ7ptOpnLw.html

Is this superior to PCC? Both use known star/galaxy catalogues and take into account filters. I’d assume their performance is very similar.

Any thoughts why I get -->Error: Insufficient data: only 1 sample(s) are available; at least 5 are required.

My version of PI has the SPCC in the processes, do I still need to install the Gaia files from the PI website? Using the process did fail for me even with the successful ImageSolve.

Great, Thanks! SO, I assume that we no longer need to do background neutralization (used to be my second step after cropping)?

If you are using OSC, there is most likely a uv/ir cut involved. So in SPCC you would want to select Ideal QE Curve and then the Sony uv/ir filter in the RGB for OSC. Cheers.
