    After calibrating frames you don't have to register and stack "manually " You can put calibrated frames back in WBPP without any calibration frames, and just check weighting, local normalization, registration and integration in the pipeline. As long as there are no calibration frames present it won't try to re-calibrate the frames. Also remember that if you're shooting OSC and you debayer as part of calibrating, you need to treat them as mono if you load them back into WBPP for integration.

      If you take a look at my previous posts, you can see the skyline better. In fact I just had tree work done that removed 7 large trees, 14 smaller trees, and bobbed some other. So it is now much better than it looks here, as my SE, S, SW, and NW horizons are pretty open. I am blocked to the North, but that is OK as the light dome of Rochester is there, and I will get those objects when they are higher in the sky. My East view is blocked by trees, but I can pick up targets as they get 40 degrees of elevation there. Compared to the narrow driveway view from my old place, this is heaven!

    Excellent series and follows almost exactly my plans as well. Had originally thought I would go with the concrete foundation and with the cost estimate also decided to go with the pole barn design. I have an open 10 acres so just have to make my wife happy about where it is all going to go and with the hopefully soon decrease in the west Texas heat will start drilling some holes and filling them back up with concrete. Keep it coming and hope it does all come together in the next month or so for you.

    Enjoyed ur video. I have multiple mono cameras. I use a zero width 54MM adapter to directly attach my 2600MM to my EFW. I then can change cameras very quickly just by unscrewing the camera from the EFW body rather than removing 4 screws. Of course u need to leave tilt plate on. What do u think?

    • @cosgrovescosmos
      @cosgrovescosmos 2 หลายเดือนก่อน

      Thanks for your comment! If you can afford to leave the tilt plate on, this can be a great solution. I was concerned about whether my unmounted 36mm filters would vignette the field, so I wanted to absolutely minimize the distance between the sensor and the filter. I sacrificed the tilt plate and bolted the camera right onto the EFW, as you saw. This has turned out well for me. The mounting is solid, and I have no significant vignetting. I also did not need to use the tilt plate. I also tend not to shift my gear configuration around or change cameras. I treat the camera and EFW as a unit, and bolting them together works well for me. With your approach, you have a much greater ability to change cameras around. And you can use the tilt plate should you need it. The only downside I can see is that the camera can loosen its connection with the EFW and rotate a bit. I have run into this before myself. In the past, I set my scopes up in the driveway each night for imaging, so the rig's movement may have caused this. Clear Skies, Pat

      Thanks for your comment. I don't expect it will bind as I am not using two V-groove tracks-just one-to avoid being over-constrained. This was recommended by Jim Collins, who builds the motor system I am using. He has done this for tons of observatories and seemed confident that this was fine. I also had this looked at by a mechanical engineering friend, who recommended placing the drive near the V-groove track.

There are a lot of things I can do on my own - and have - but mechanical things and metal work are NOT in my tool box. That is where friends come and are willing to help. Having that help and doing a project in more of a team mode make it so much more enjoyable and rewarding! Having a good Man Cave is a must for projects! I'm glad to hear that you've created yours and finished your first project! Congrats! Now that you've started, I'm sure your mind is swirling with possibilities for what to do next! Enjoy!

    Wow, love watching that laser doing its thing, reminds me of being back at work at 3M UK, .we used lasers for cutting all the abrasives, albeit a little smaller, but not much…great video. 👍🏻

      Ahh - I get it now. I suppose using a traditional cutter for that kind of work would be self-defeating - the abrasives on the sheets would always be wearing down the blades. Kind of tough to wear down a light saber!

    If you go to your local metal recycling place they will most likely sell new and USED metal in all kinds of shapes and sizes. Usually for a few bucks a pound. I bought a 4 in and a 6 in metal tube, cut to length on the yards bandsaw. They even have offcut scrap. I found some perfect triangle pieces to use as supports and also a square plate 1" thick and a round plate 1" thick. What I brought home was already cut and the plates had holes in them for bolts. I paid 90 bucks for all the steal. Using the flat square plates on the bottom and the round on the top with the triangle pieces to support the bottom. I use all thread embedded in the concrete and I turned a cast iron adapter that is IDENTICAL to the top of my tripod so my mount would bolt to it with the same adjustability as I would have on the tripod. I used elongated holes on the base to allow for some rotation adjustment. And I used large bolts with a series of two nuts on each bolt to the round adapter plate to allow for some leveling adjustment. Once it's all set, and polar aligned, I should be able to forget it.

    Another great video and nice to see it moving forward, FWI the pier does not have to be perfectly level, that’s what polar alignment is for….👍🏻

    • @cosgrovescosmos
      @cosgrovescosmos 4 หลายเดือนก่อน

      Thanks so much! I know that polar alignment and the alt-az adjustments on the mount can compensate for level and such - I was just a little paranoid that the foundation and bolts would go in wrong, and then I was in trouble. And I would be if the error was greater than the alt-az adjustment ability of the mount. So this way, I can tame my paranoia! :-)

    • @astrokev99
      @astrokev99 3 หลายเดือนก่อน

      An excellent and valid point. It amazes me how many people are convinced that a perfectly level pier is absolutely essential for accurate polar alignment. As you say, it doesn't matter one iota!

    I wanted to follow your workflow of creating a SHO - Image using the Color Combination tool. Unfortunately PI refuses to CC stating that it works only with RGB - Data. I tear my hair out with PI!

    • @cosgrovescosmos
      @cosgrovescosmos 4 หลายเดือนก่อน

      Hmmm - not sure what is happening there. ChannelCombination really does not know what you are feeding it when you select the files for the so-called r, g, and b fields. Are you sure you ae grabbing the right tool? You mention "Color Combination" and "CC" - CC usually refers to a color calibration tool, and that one does care about it being an RGB file. ChannelCombination takes 3 mono images and combines them to form a 3-layer color rgb image. If the files you hand it are really S2, Ha, and O3 ( aks SHO), then it will form a color file with those. But the input files must be single-channel mono files.

      Very strange - I am not sure why you are running into this problem. I do this all of the time, and in fact, as a sanity check, I just went over and tried it again. Worked without problems. Sorry - I seem to be no help to you for this one!

    Hi, thanks for the intersting video. My question: In your workflow (0.21 min into the video) the shown starless images are already nonlinear. Is LF then appropriate to use as it's no linear data anymore?

    • @cosgrovescosmos
      @cosgrovescosmos 4 หลายเดือนก่อน

      Great Question! Linearfit sounds like it is used just for linear data. However, the name is really just referencing the numerical methodology used to put the best straight line through the data being modeled. It can do its job as long as there IS a linear relationship between the two data sets (in this case, the reference image pixels compared to the target image pixels). Now - it is more likely to work best in the linear domain as the mere act of stretching introduces nonlinearities. However, that does not mean it is not useful in the nonlinear domain. Some of the areas of nonlinearity are concentrated towards the toe and shoulder of the curve, so by clipping those, we concentrate on the middle portions of the curve, which can be fairly linear. The example workflow shown here is one I had used extensively for NB images. I should point out that BlurXtermintor has caused me to change my workflow. It does its best job when dealing with three color layers at the same time. So, I now create my SHO images in the linear domain, run BXT, and then go nonlinear. When I want to work on individual color channels, I extract them from the color image, enhance that layer, and then recombine them. So, these days, I tend to do this in the linear domain, and linearFIt is used there. But the key takeaway here is that LinearFit can be useful any time you are attempting to combine unlike images.
