Hi James - I couldn't try PHD2 because I was inside, but, APT did say that it was connected, so, I think it is OK.
I got the ZWO Ha and Sii in according to ZWO guidelines. I'm hoping I have the Chroma 3nm Oiii in correctly because I couldn't find any guidelines from Chroma. I'll find out soon enough.
I was very surprised when everything worked the first time!!!! I kept waiting for the next piece of equipment not to connect, but, it never happened.
Can't wait to give it all a try. I need to have data so I can learn how to process NB images (HOO, SHO).
PS: I notice you live in Orange County. I used to live in Irvine a little over 30 years ago (College Park development just off of Culver). It sure grew fast.
Well I am sure PHD2 will work! The only reason mine didn't work is because I selected ASI Camera 1 in both APT as my imaging camera and PHD2 as my guiding camera, when PHD2 should've been ASI camera 2. Luckily you won't have the problem!
That's awesome! That never happens haha
It isn't too bad. PixelMath can be your best friend. The way I do it is I basically process three separate images to the stretch (Crop, DBE, MaskedStretch, LinearFit, and then curves transformation), and then combine them. Others probably do it differently, I have heard of people combining straight away and doing all of the processing on one color image, which is easier but I feel like you have a lot more control over the images when you do it all separately.
I would highly recommend taking a look at https://www.lightvortexastronomy.com/tutorials.html
, specifically these tutorials:
-Preparing Monochrome Images for Colour-Combination and Further Post-processing
-Narrowband Bicolour Palette Combinations
-NGC7000 North America Nebula and IC5070 Pelican Nebula - CCD Narrowband Bicolour
-Narrowband Hubble Palette
-Combining Monochrome R, G and B Images into a Colour RGB Image and applying Luminance
-Combining LRGB with Narrowband
In that order! Even if you don't use that exact process, there are a LOT of great tips in those tutorials... I learned a ton from that site, and it's free!
I would also recommend downloading the Multichannel Synthesis scripts, which make it easier to play around with the different color combinations you can do. I have been playing around with my old Canon data, separating the RGB channels, and combining some SHO with the canon data... It's pretty fun! Even though my imaging scale is a little different between the cameras, The star alignment tool is so cool and will scale the images for you perfectly! You will have a lot of fun playing around with narrowband
Again, you get to go back through half of the messier list!
I would offer up my data for you, and I can if you really want
, but I am sure there is much better data that is on par with what you will be able to do from your darker skies. My data is messy and cloudy from the LP. While it is a challenge, it is probably not the best to learn with
You probably won't need it before tomorrow! You will be shocked by how noise-free a narrowband, cooled image is, even if you only capture 30 minutes of data.
And BTW, you have no idea how lucky you have it that your mount powers your cooling for your camera!! One of my biggest pains is the super heavy AC cord for my camera T.T
No way! Irvine is 20 minutes from my house. I go to CSUF, and I'm applying to Irvine Law for the fall
