What is the difference between broadband and narrowband astrophotography..
Also, what is the most important piece of equipment for astrophotography?
I have the answers to those with a look at several different nebulae and a special look at a galaxy hidden beyond the view of the beautiful Pleiades star cluster. CAN YOU FIND THE GALAXY IN THE PLEIADES?

You are very welcomed. I am currently shooting the Helix nrebula with the Optolong L-Ultimate and am amazed ar the results. This will be my next video

Hi Martin, Well, that makes us somewhat even as I am very jealous of your fantastic observatory. There is absolutely no way I could ever construct something like that. You should be very proud of it.

Thanks, Joe. I'm working on the Helix nebula now, but had to wait for the ball of white night light to get out of the way.

You can also get some good results by adding the Ha data as Lum on the RGB data of the California Nebula. Good job explaining these differences. CS Tim

When you zoom out of the Bubble Nebula, it looks like a face of a skull with the lobster claw and the other one on the right, next to the Bubble Nebula. What is also strange was when I was looking at the Lobster Claw Nebula in a photo, it also looks like a person wearing a cloak. He looks like some sort of Sorcerer or something. And you said this was near Cassiopeia? What an odd event for those Super Novas to form in a shape of what we humans see that is familiar to what we have on Earth...except the Sorcerer part. But inside the Queen constellation is somewhat strange to me.

Nice video Pat, The same thing happened to me with the horsehead nebula, it was almost an obsession, I live in a city with bortle 9 skies and it wasn't until I used the optolong-lenhance filter that I was able to get good results

Hi Jacinto, Yes, there is some thing about that Horsehead that just facinates me. The L-Ultimate is performing well on it too. I do have the L-eNhance too and love it.

Really great video. Enjoyed it so subscribed but i am visual only. I have an insanely good figured F/9 100ED. Killer contrast so the SECOND best thing for AP would be a VERY GOOD apo for the very subtlest of details. Perhaps I will try a camera out soon. Any suggestions for a good 'un ?? Thanks !!

Hi Lance, Thank you for subscribing to my channel. A good dedicated astro-camera would be the ZWO ASI 071mc or the new Player One Poseidon-C Pro (IMX571. Great cameras but at a shocking price tag. I have the 071 but I plan to eventually get the Poseidon-C Pro in the monochrome style.

Hi Pat I like listening to your channel. I am part of the Minnesota Astronomy Society and I am up at Hilton Head Island for the week. Are you going to be up looking at the Lunar Eclipse on Tuesday morning? If so would you like some company? I don’t have my telescope with but I do have my binoculars. Let me know if you wouldn’t mind somebody looking over your shoulder I would drive down from Hilton Head.

If you like wide field of view with rich colors, then rid off ED80, and get Officine Stellare Veloce MII.

May ask what the Hubble pallet is or do you have a video on it?

@HeavenlyBackyardAstronomy Жыл бұрын

The "Hubble Palette" is from using narrowband filters and substituting the filters into the Red-Green-Blue channels for the combination. The actual palette is Sulfur 2 filter in the RED channel, the Hydrogen Alpha filter into the green channel, and the Oxygen 3 filter into the Blue channel

What about Hbeta and Hgamma? They will make some differences for your photos. Are you going to conduct spectroscopy study on Emission Nebulae?

Hi Pat. I've been looking for a clear explanation of the difference between broadband and narrowband. Are 1 shot color and rgb pretty much the same? What scope are you using on the cgem? Thanks so much!.

@HeavenlyBackyardAstronomy Жыл бұрын

Hi Perry, OSC and RGB are NOT the same. The OSC (One-Shot-Color)uses 4 pixels for the color ... one as red, one as blue and 2 as green. It is then blended together inside the camera to produce the color. The RGB is a monochrome camera where all the light goes into each pixel. So with the red filter on, all the pixels see the red, and so forth for the green and the blue. The color is produce in the software on the computer. Usually, the resolution is much better for the final product from the monochrome camera versus the OSC. The other difference is the "ease of comfort" for the OSC. There is no blending needed in the software where in the monochrome, you need to process the three different images first, then blend them togeter to get the color image, hence more work needs to be done, but overall, worth it once you see the final product ... in most cases

What would you get for dso's(assuming you have a dslr and a good tracking mount) A 6 inch f5 newt or a 6 inch rc

@HeavenlyBackyardAstronomy 6 ай бұрын

Well, it is my guess, you would get some extremely fine final images. At f/5, you would enjoy having a wide field of view which is necessary for many nebulous targets.

When you are shooting the Narrow Band Filter is this using the OSC or the Monochrome? If you using monochrome are you taking each picture of each setting with a certain filter applied?

@HeavenlyBackyardAstronomy Жыл бұрын

Hi Paul, Thank you for watching my video. The narrow band is shot on the monochrome camera (ZWO ASI 1600). The settings were all the same ... 180 seconds at the unity gain of the camera, which is 139. I also shot the same number of images for each filter ... in most cases were 180 seconds per filter. I did do an auto focus when I changed the filters. For the calibration frames, I made flats and dark flats for each filter. Dark frames were all the same So the way it proceeded was 20 frames for Hydrogen alpha, then change filterto S2 ... auto focus ... take the 20 frames for S2 ... change filter to O3 ... auto focus then take 20 frames for the O3. I stacked each filter set of images in Deep SkyStaker and processed them in PixInsight and then merged the monochrome images into the color palette via "channel combination".

What is the name and model of the windows 10 computer? Where to get it? Thanks

@HeavenlyBackyardAstronomy 7 күн бұрын

Hi Mike, The mini-computer is just a generic modest price Windows 10 Pro computer, but today, those are equipped with Windows 11 Pro. To communicate with an indoor desktop computer, they should be the "Pro" version of Window and on the same network, however, you might get away with using Chrome's Desktop Sharing. I usually use Window's Remote Desktop. All the telescope software needs to be loaded on the mini-computer including ASTAP and it's database for use in plate solving. I also have ASCOM platform, NINA, CPWI, (for Celestron mounts), EQmod (for other mounts), PHD2, Pegus Unity platform for the power box and focuser, and SharpCap (for planetary capture). I have NINA using "Robocopy" plugin to transfer the incoming subframes to my network drive. I hope this helps
