So, I've been collecting data on a couple targets. NGC 7635 and NGC 6853. I have a lot of data on different nights. I recently purchased a Radian Triad Ultra narrow band filter. The images that came through on NINA raw data are fantastic. I haven't started the processing yet. Here's my question. Can I combine the data unfiltered with narrow band filtering data? Would this combination be beneficial to the final image, or would this defeat the purpose of the narrow band filter?

Just a quick question. I'm using a QHY268 color camera. I found somewhere, which I don't remember where, that the Bayer matrix is RGGB. I have run 40 plus lights, darks, dark flats and flats through BPP in Pixinsight. I've done this with several targets now. Only once after stacking my master lights did I ever get a green cast. All the other times I get a red cast. I've looked over and tried several settings just to experiment. I'm just not sure why only once was it green? The red cast seems to be fine, and I run through processing just like the green and all is well. Just thought it strange and curious why.

Well, this could end up with thousands of thoughts however, my new system, SVA130 Stellarvue and all its gear came in at 49 pounds. I have read about all I can stand and watched tons of reviews. Just thought I would try a direct opinion or two on a new mount decision. The EQ6R-Pro I was using as my main scope mount is only rated at 40 pounds. I have read that it's best to only load to 3/4 max load for best tracking. I have a Paramount MX+ however it has a system going on it that will be permanent. I also have a Celestron CGX again it has a Celestron Edge 11HD on it. This leaves me needing a mount in the 60-pound minimum capacity. In that range it is kind of limiting my choose. Seems like that area is an empty zone. I have been looking at the iOptron CGE70G. Some of the reviews are kind of iffy, if you know what I mean. I looked at the SkyWatcher EQ8 series but again it jumps not only in weight capacity to 110LBS but jumps in price also. I have had several mounts and still have probably more than I need I'm just hoping this is my last one. Not sure what I'll do with my EQ6R-Pro but may set it up later with an 80mm scope or something. I would value your opinion. Thank you very much.

I'm running a Primalucelab Eagle 4S on my main scope. I was running an Eagle 3 and had the same issue. Now I've ran the Eagle computers for a while now but never with a QHY camera. I was using a ZWO camera prior. The Eagle is a power distribution box as well as onboard computer with all the acquisition software. I've been setting the entire system up starting with the Eagle 3 that had been used flawlessly on another rig. I started having issues when activating the power to the QHY camera. The Eagle would shut down and I would have to reboot the entire system. I moved to another power port, and it worked fine for 3 or 4 times, so I thought it had to be the port. I sent it in for repairs and have not heard anything yet. Meanwhile I receive the new Eagle 4S I had on order for another rig I'm putting together, and I install it on my present rig. Everything started out great. I loaded ASCOM, EQMOD, N.I.N.A., ASTAP, All Sky Plate Solver and all the drivers for the onboard equipment. All is going great. Again, I figure the Eagle 3 had a problem on the one power output port. Then bam! the Eagle 4S does the same thing when I start up the QHY camera. It had been working fine during the setup. Now the camera says 3-amp max, and I have it on one of the 8-amp ports. So, I'm sure it's not overloading the power port. The camera is new and has never even taken a single shot yet. If I disconnect the camera and power up just the output port, then while the port is live, I plug the camera in as if I was the switch it seems to work fine. Anyway, this may not be a problem that any of you have had but thought I'd run it by you folks to see if any of you have had issues with the QHY cameras. Maybe it is just a bad camera although it powers up and runs fine more than half the times I've started it up. Kind of a strange issue for sure. Has anyone else had issues with a QHY camera? I've been looking at a full frame mono camera. I really like the data coming off the Sony IMX455 chip and thinking about either the ASI6200M or the QHY600M. These problems are causing me to lean toward the ZWO. Hope I could get a little feedback. Thanks

So I've been setting up my Stellarvue 130. On my old system I was using the ASI294 color pro. I could align and focus during the day on far objects and basically work out the bugs prior to setting up for a nights imaging session. I now have the QHY268C mounted and setting it all up with focuser and other accessories. I seem to be missing something. I use APT as my capture software, although I have been giving thoughts to something else. I have all the drivers installed and APT recognizes the camera and all went good until? I try capturing a distant object during the day like I did with the ASI294. I turn on and off the auto stretch function and decrease the exposure time to .01 seconds and lower, all I get is a solid white image. I've altered the binning with no luck. I tried a few dark shots with the lens cap on and I get a smooth dark grey field very similar to the images shown on the QHY web page showing the zero amp glow. My dark images however do seem a little lighter grey. Just not sure if that's normal for the IMX571M chip or not? If I could get a clear evening, 😥, I will try some stars but seems like I could get an image of distant landscape similar to the ASI294. Anyway I would appreciate any input, thanks!

Well I still struggle understanding the advantage or benefits of using a focal reducer. Although I've read about all I can stand, my pea brain still hasn't understood the advantages of using one. So in photography we try to gather light photons and direct them to hit our sensor. The more you gather, up to a full well or saturation, the better the resolution hence detail. In my thought process it seems that by reducing the focal length you are condensing the photons onto fewer pixels. I would think that spreading out the targeted image onto a greater number of pixels would give you better detail wouldn't it? I have read about the shorter focal length increasing the field of view and decreasing the F/ number. When I use Stellarium and plug in my scope then plug in the reducer, as I switch between the native length and reduced length the image becomes smaller. Wouldn't this be gathering more photons per pixel of the target? Wouldn't that reduce detail? Maybe I'm missing something. I would think more stacked images with fewer photons per pixel would give greater image detail. Anyway if someone could clarify this that my pea brain could get around this it would be greatly appreciated.

I have a Stellarvue SVX152T. It's a little big to be considered portable although you could lug it around. Well I've been looking for something to replace a Vixen SD115S. Low and behold I just bought a single owner like new Stellarvue SVA130T with all the original case, manuals, 90 degree viewer and everything off eBay for 2500 bucks, yahoo! I'm going to set it up with me QHY286 color camera.

So I have a new Stellarvue SVX152T. I ordered it with the Moonlight focuser, field flattener and reducer. I was just getting things setup in my garage and thought I would focus in a couple 2 or 3 miles away with the camera and no flattener or reducer. I found that the Moonlight focuser doesn't have enough travel to bring it in focus. I talked with Stellarvue and they suggested experimenting with different spacers. Well that's going to get costly because of the size of threads and adapter to just try. Was curious if there is a way to calculate the focus point? Also I'm sure pointing at some distant galaxy the focus will be in a different location. This will be a permanent mount in my observatory when complete. Any thoughts on going about getting in focus? I did buy a tripod with the Paramount MX+ so I plan on setting up a few times in the yard until the observatory is complete. After it's permanently mounted I'll sell the tripod. I do have the 55mm distance ready to go when using the flattener and reducer. Just want to be able to use it in it's natural focus length for different targets. Thanks for the help

I recently purchased a QHY268C to upgrade my ASI294MC. don't like the amp glow on the 294. I would like to have a manual filter drawer on it and was looking for adapter rings. Where is the best place to find adapters? Has anyone tried the custom built ones I see offered her and there? Thanks

So I've been running APT for my capture software. I do have a new system that isn't quite ready to operate, it will run TheSkyX. Back to the APT system. I use it for plate solving as well as capture, mount and all hardware control. I'm just not real happy with it. Seems like the plate solving only wants to work correctly about 10% of the time, maybe less. Gets a little frustrating. I get the Runtime error overflow so I reload the plate solving software again and it works for a while then decides to take a dump again. Then other times it just seem to take forever, an hour or more, to solve the photos. I get system program not responding and forces a restart and just things like that. When it works it seems to center the frame real well just loose too many night fighting the software. Well enough about that. I would like to know what others are using for software and how they like it. Thanks
