One small but seems to be important point to add FYI - in step 1 it's important to check Distortion Correction at the bottom of the page to minmize possible star distortion along the overlaps.

Hi Russell. I’m thinking of upgrading from my z73 to a fra400 which is what you did I believe. Did you ever use the f3.9 reducer and was it any good? Less exposure time and a wider fov both sound nice to me. Would you say the upgrade is worth while or are the scopes too similar and it’d make more sense to go for something bigger? Maybe a fra500 or 80phq….

I haven't used the reducer with that scope as I also have a redcat 51, but I did use the reducer with the PHQ80 and I was very impressed. I made a video about that which you might find useful. here's the link if you are interested kzread.info/dash/bejne/hq6hp9mMp8y7hM4.html Regarding the other scopes, I've not used the FRA500, but I have heard very good things. I absolutely love the Askar 80phq, it is a brilliant telescope. If I had to pick one between the FRA400 or the 80phq (it would be a very difficult decision as they are both fantastic) I would probably just lean towards the 80phq. The stars it produces are fantastic and have a slight edge over the FRA400. The FRA400 is cheaper though and faster at f5.5 vs f7.5. I hope this helps? Any other questions, just shout.

Great workflow video Russell. This looks a lot easier than the method I used once in Pixinsight a while back. You mentioned about APP - I use that for mosaics and it works brilliantly and can be done all in one hit when you are calibrating and stacking the images and will spit out a calibrated, stacked and mosaic’d image at the end for each filter (it’s in my Vela Supernova remnant video). The downside is it is an extra cost to buy APP.

This is one of the best videos for a mosaic in Pixinsight that I've found, I'm going to use this method when I process my heart nebula! Much appreciated.

Wow, I had tried the "Star Alignment" method from another person who posted a comment on your present one. That process I found very tedious, and it was easy to get mixed up with where you were, especially with 4 panels! By contrast, this worked the first time! I can see 1 or 2 star artifacts, so I am running it again with a higher "feathering number". (Result: still a star artifact right at the meeting point of the 4 corners) This method took minutes compared to several hours for the other process I tried. You know, the "problem" with these mosaics is the camera angles. With Telescopius/ASIAIR/PixInsight combo, it is VERY difficult to get the angles and overlaps right. So I think I should just install the camera on my RASA, shoot a preview at the target area, note the camera angle, and then put that into Telescopius and make that the reference instead of trying to match the camera to Telescopius. Even then, Telescopius shows slight variations between the panes of 1 to 2 degrees. That's too much to ask, rotating the camera out in the dark by tiny increments, what do you think? Anyway, I am amazed that you sat and tested increments on the Gradient Merger Process. This video basically saved my project, and I had tremendous difficulty getting PixInsight WBPP to be able to successfully generate my 4 panels when they were all put in together. Later: was happy with photo but I could see the lines of all 4 panels. And when I would use masks, they clearly showed the bullseye target on my image. My camera angles were tilted down top and bottom on the left side, so getting that part right is really hard. Much cropping required.

So glad you found it useful and it helped with your data. Like you I tried multiple methods and thought I wasn’t going to get it to work, then I found this approach. Yeah I’ve heard of a few reports of the telescopius coordinates being slightly out, I’ve not had that issue, however I have only done a couple of mosaics. I think the biggest challenge is getting the rotation of the camera spot on. Making a note of your camera rotation first seems like a very good idea, this makes way more sense that making those small changes trying to get it spot on…which I what I did 😂 you’ll have to let me know how that approach works. Thanks very much for watching, clear skies 👍

@@RussellsAstrophotography Yes, to match the camera to Telescopius is tedious in the dark, and after every tiny camera twist you have to reshoot a preview and then recheck the angle. It's a pain. And then, every panel needs to be about 1 degree different? Oh please! If I could afford a Planewave then perhaps I could also afford a camera rotator. As I said my left side panels were canted compared to the right side and I was lucky I could still get something after significant cropping. BTW, I believe that the "Lazy Geek" suggested to take the camera angle to Telescopius instead of vice versa, and when I first watched his video, he lost me with that. Now I see why.

Good tutorial. We will try it. What about acquisition of these 4 frames? Are they identical? Did you crop them before stitching? Did you do DBE and color calibration before stitching?

I tried it and failed at first, but then it worked when changing the pixel size to match my camera. Just a tip :)

Hi, watched some of your videos and they are very good, this one seems to be the best I have seen re mosaics however, not one to assume but in this video where is your starting point? It looks to me that you have calibrated the separate images and created a master light for each one, is that correct? Also, what process has each image undergone to get to this point, stretched, denoise, star reduction, curves etc? A small critique, this information would be helpful to a newbie like me. Thanks.

Great video Russell. What steps would suggest with LRGB. eg create a L mosaic then a RGB. Then process and combine ?

Hi Russell Great vid many thanks.I also had all sorts of trouble with mosaics if ICE didn't work. Question though I see your image is taken with a color camera.I was using an ASI2600MC .Do you have to process each pane to at least de bayer them.Just to try your method I put the unprocessed images in Pix and it did a good job but trashed the colour data.It would be great to be able to join it all together and then process it but by the look, this doesn't happen. How do you de bayer to make sure each pane matches?Be easier if you could do it at the end Many thanks Stu

Thanks! This is super helpful. However, I'm having an issue. I created a nice mosaic of the Heart and Soul Nebula but when I try to run SPCC on it I'm getting error messages. This happens even if I run Image Solver before going to SPCC. Any advice appreciated!!

Thank you very much for such a clear explanation video! However, once I use the "MosaicByCoordinates" script, the resulting registered images come totally white. I cannot get through this. I can perfectly the STF streched panels once I run "ImageSolver", but not after when they are registered. No errors appear in the process. Maybe I am missing something? Thank you!

Hi Russell so I tried this last night a 2x2 and although I have merged everything its not the same as it is from Telescopius. I suspect its to do with the camera rotation. When running the plan I checked the new AAP rotation function which I think is the same as plate solving and checking the degrees and then matched that within a degree of Telescopius. I am bit confused as in Telescopius there is a position angle and a equivalent to in my case 239.3 position and -120.7 equivalent. I used 238 on AAP and its miles out. Any ideas? Thanks

Another way to merge but it seems like to top right panel is darker?

Mr Russell, I only just now noticed that in Telescopius, a default setting for camera rotation for cameras with a rectangular lenses (like our ASI2600s) requires a rotator. Well who has one of those. Without a rotator, the panels cannot be "perfectly matched". But in a mosaic, the camera rotation is critical. To get the same camera angle for each panel, did you turn that feature off? I didn't realize it was there. But then, how tolerant of not precisely matched panels is WBPP in PixInsight for mosaically registering and normalizing the frames to each other? For me, WBPP can't even get that far. Next time I will at least turn off the camera rotator option. I think my panels were off perhaps as much as 2 degrees.

Hi Paul, I didn't have that box checked no, I just tried to match it as best as I could with the rotation of my camera. I have a manual rotator built into my Askar telescope, so just eyeballed it to begin with and they had a few trial and error attempts until I got the camera rotation as close to the telescopius preview as I could. The key thing is to make sure the overlap tolerance is high enough, then you should be ok when it comes to processing the images. I hope this helps?

@@RussellsAstrophotography Yeah, as I had remarked, I plan to bump it up from 20% to 25% overlap.
