Well done Chad! I tested this last week and it was spot on, no tilt after adjustments, with my edge11 and 6200mm. I am so glad he made this plug in. In the past, I would have to manually do an autofocus run and watch all four corners to document my focus locations to adjust tilt which was very time consuming, and now it is automated. This will be the go to platform for tilt adjustments, ASTAP does a good job and never had good consistent results with CCD inspector, but this plug in will be the way to go from now on and will only get better with time. Thanks again for your time spent and keep up your hard work and dedication! P.s. thanks for the shot out to my good friend James Lamb! I am sure he would appreciate that.

I have an Edge 800 and am seeing a lot of spherical Aberration from center to edge. I am guessing it is my back focus but I was at a loss for how I would know without trial and error. Now I have a tool that can help me make more informed choices. You did a great job organizing the information and building this video. I look forward to many more of your videos in the future! 👍

@@PatriotAstro I discovered my imaging train is 28mm short. I actually used Astrometric Stacking Program and FITS Viewer (ASTAP) to see the distortion of a few of my images to understand how misshaped my stars are from center to edge. And the pattern matches that of my back focus being too short. Then I took everything apart and realized I had miscalculated the distance many years ago when I first set things up. I decided this would be a good time to change to a better OAG and guide camera to get a larger field of view for guiding. Soon, I will rebuild the imaging train and remeasure the distortion. I have made good use of Nina's focus tools already and hopefully my guide stars will be much more "normal" after I get the back focus dialed in. One question - if I have Nina run auto-focus periodically throughout the night, that will cause PHD2 guiding to get messed up. Do you have any tips on using an auto-focus and guiding at the same time?

Great video instructions! Highly appreciated that you have taken the time to walk us through Hocus Focus. For me as someone who is new to auto focus in astrophotography I was able to set up my focuser within 5 minutes to reach a match of the focus trendline of 99%. 😃 I am totally impressed of the precision of these little gadgets and the software that is controlling them. Just one little additional feature I would like to see in the Equipment -> Autofocus. Today there is just one field to specify to which step the focuser should move. I would love to see two additional fields to enter values. Many people don´t have their rig set up all time and have to set it up each night of photography. Target position (the one present today) Full Retraction of focuser (for storage) Go to point of Focus (initial move of the focuser to a predefined point) This would give the user two fixed fields to start and end the session plus one field to optimize the starting point of the focus routine for each session. This way the user would have the possibility to move the focuser like today but also to predefine the focuser position to store the telescope with retracted focuer. On top the focuser can be moved by one click to the position of focus when setting up the equipment. As you seem to have good connection to the developer I think placing such enhancements to you may lead to higher chance of success if you find them useful too.

@PatriotAstro Жыл бұрын

I can see where you are going but I think some of this ends up being sort of relative depending on if you physically move the tube/configuration, etc. I do see where you are going with this and will need to think about it a little more.

@@PatriotAstro Thanks a million for your answer. I think it does not be too complicated in terms of design. Just 3 fields to enter the step where to go with a Go button. One named Fully Retracted, one named Tested Focus and then the field that we currently have to just go to any step. So just a little helper to get rid of additional files where we have the focuser steps for full retraction and the tested focus stored. 😃

@paulwilson8367 Жыл бұрын

Ha, well that was the most difficult video I have tried to watch since first trying PixInsight. I have the RASA 8, and like your comment, my "corner stars are trash". They are egg donuts. ASTAP describes my subs as having "extreme tilt". Most people seem to think that their problem derives from camera sensor tilt. Well, I have 2 cameras and both of them (ASI 2600s) have almost the same bad corners. I performed the experiment of rotating the camera 180 degrees with subs before and after. Strongly on both cameras, the tilt rotated with the camera. ZWO says that's tilt in the optical train. I switched from my Starizona Filter Holder, which is supposed to nail the backfocus to an engineered adapter of exactly 28.73mm, the ideal back spacing. Neither of these adapters helped the tilt. Ok, if it doesn't like "ideal" what does it like? I have added shims to the Starizona, but so far no improvement, so I will start going the other way. This is where NINA comes in. My ASIAIR Pro, so easy to use, won't help me with this, so I have purchased a mini pc for NINA and Hocus Focus. Getting it to recognize my equipment. I looked at defocused bright stars and they look round, but collimation will also be ruled out. So many people seem to be buying the hyper expensive octopi to just twist out the tilt from "wherever it is". But wait, I have 2 cameras! 2 Octopis? No, why should I be limited to 1 camera? That's not right. The RASA might end up getting a ride back to California. For the price of 2 octopi, I could buy a nice Newtonian and rule out where the tilt is. I don't imagine no tilt, but I do imagine "Mild" tilt, not "Extreme". I will be watching your video again and Lamb's until the procedures are more understood. Wish one of you used a RASA, it doesn't use a flattener.

@PatriotAstro Жыл бұрын

I completely understand the frustration. And it can be challenging to sort out where the tilt is coming from. shim after shim, and test after test until you get closer and closer. At some point hopefully you can get it to be 'good enough'. I too wish the correction solutions were more affordable. I'd love an octopi myself!

One question about Autofocus, what is a good HFR ? The less is the better. But for exemple I'm using filter in front of an asi533mc, I need to add spacer for the backfocus because of the filters and I guess I can find what is the good number of spacer I need to add with the HFR ?

@PatriotAstro 2 жыл бұрын

I used the Celestron one for years and it was ok but I was always frustrated with the stars in the outer 30% or so. I had to crop a lot, or just live with egg shaped stars. And that was with my 1600mm, when I put the 2600mm on there, I found it pointless since the additional sensor space was filled with bad stars. From the documentation, it seems that the best image is at 105mm backspacing from the end of the reducer optics to the imaging sensor. I tested 20+ backspacings at 105mm, inside 105mm, and outside 105mm. I never got a flat field. The docs also say it is a reducer/corrector, but they lean away from "flattener" and never say they will provide a flat field, just a better corrected field than if you were not using it. The Starizona IV is not perfect either but it is far better and much flatter. The other thing I like about it is that when you use their 2-inch sct back to connect it, the length pushed me beyond my focuser so my rotator can work without colliding with anything. Anyway, after a bunch of research and forum user reviews, I moved to the starizona and am much happier with my images now.

Super nice video! Thanks, Chad! Stupid question: is there any way, with or without hocus focus, to have some sort of temperature compensation to gradually update focus between each sub without running a full autofocus routine? I think that would great. Thanks!

@PatriotAstro 2 жыл бұрын

You can enable temperature compensation in NINA if your driver also has it enabled. I haven't used this honestly as it is kind of inconsistent for me depending on the speed of the change in temperature and the timing of the thermal effect on my equipment. There is also a trigger that will kick off an autofocus if a certain about of temp change has occured, and there is another instruction that can move the focuser based on a slope/intercept model. I think most people today are using the "AF on HFR Change %" Trigger instead to correct for any detected AF requirement wether it be temperature or airmass, etc.

Thanks! The Starizona reducer is night and day to the Celestron one. So much better all the way to the edge! I guide my SCT using an OAG.

It’s been cloudy here in Northern California so I watch you auto focus video again and being that I have a C8 with the celestron 6.3 corrector I’m thinking about replacing that reducer flattener with the starizona. Then I think why not sell the C8 and get the edge 8. I noticed that some subs had tictac stars like nearly half with 5 minute exposures. That could be something else in the imaging train or phd2 issues or cable management . I don’t get that problem with the Stellarvue 102 apo or spacecat. So is is just the field of view outer edges it does better or it just a better over all Star correction. 400 plus tax but we get what we pay for. Thanks

@PatriotAstro 2 жыл бұрын

SCT telescopes are so challenging from this perspective. Eccentric stars really could be a number of things, but assuming that you’re not running into a physical issue and grading properly on a decent mount… It’s almost always just going to be a nature of the optics themselves. Backfocus, collimation, quality of the mirrors and mirror movement, etc. SCTs require a flattener of some sort to correct for the problems with the design itself. The Starizona flattener is far superior to the Celestron one. Now with that being said, the other problem we have is that as we mature as astrophotographers… We buy better cameras with bigger sensors. Bigger field of view means trying to grab more light further away from the center… Which is really not what an SCT wants to do. :) At the end of the day, an SCT is extremely challenging… But once you begin to master it, is one of the more flexible designs allowing you to get great views of nebulas, distant galaxies, planets, and the moon. The sun, well that’s not really practical with an SCT… But that’s why we buy a second telescope. :-)

But, Hocus Focus does have superior detection algorithms, and there’s no reason it shouldn’t work for everyone. But again, there is 100% nothing wrong with sticking with Nina‘s process if it is working for you. If it’s not broken, don’t fix it. :-) glad to help you try to get it working if you want to give it a shot.

With long focal lengths, especially without a reducer, definitely adjust some of the parameters as I do in my video.

I haven't had to use it in a while so I can't tell you for sure... AND it also can be affected by your type of scope and whether or not your image is flipped, or your camera is rotated, etc. Best bet is to take a picture with something in front of an edge of your optical train so you know what's what... Basically, clip a treeline, roofline, or hold your hand in front of the top of the tube while taking a picture, from there you should be able to sort out up/down/left/right and map it to your sensor tilt.

Hey Chad. I installed HF and tried to use it for the first time last night. (I have NINA's regular AF working fine, but I was curious to see if HF would do a better job). I switched on the annotation option, but I can't get HF to annotate the stars in the image window. Not sure what I am doing wrong. It also gave me very weird focus curves on a few trial AF runs, so I have - reluctantly - switched back to using NINA for autofocus. Do you have to change all your settings between NINA's AF and HF? I expected it to just run ok based on my NINA settings.

@PatriotAstro Жыл бұрын

You should be able to start with NINA AF settings and go from there. The HF stuff is really more about tweaking the Detection settings since once you enable HF for Detection and Annotation, it uses those algorithms rather than the NINA ones. If you look up my email address on the about page of this channel you can send me some screenshots of curves and config info and I can try to help you along. Also, if NINA is working for AF for you, HF isn't necessarily required. NINA can work quite well. HF can be a little faster and work better with certain focal length scopes, etc - but not a mandatory plugin if you are already happy.
