Great. Thanks, Cuiv. Very useful. I'm just switching to NINA after buying a mono camera and 7 pos EFW.

Again I learned more good stuff, I was confused on how the offset setting was used. Not any more! PLEASE, Keep going with your tutorials! Using an ASI183mm-pro with my old Stellarvue SV80s triplet along with an ZWO autofocuser installed a few months ago. I live in the desert so many clear sky nights :)

I'm so jealous of anyone living in the desert, getting many clear nights, not having to deal with dew, and having dark skies... just great!

Thanks for the video! And how does NINA determine which way to move the focuser for a certain number of steps?

To help out the mic to not pick up the wind noise so much you could put a small piece of foam around the mic, cutting a small hole in the foam and setting it on the mic. Just be careful to not allow anything in touching the foam...

Thank you! I'm no longer using that mic (now Rode VideoMic Go or something like that), and ended up using it under the t-shirt when I did - it worked quite well. Thanks!

Very nice

Very nice concept and great video, Cuiv. I have NINA set up and been going through your videos and love them. I'm hoping you will do one on the Flats wizard. One on the manual rotator would be much appreciated as well. I always travel to a site so trying to get the angle the same is important but I didn't even see a way to bring up an image from a previous session.

You can bring an image in the framing wizard, by selection "File" as the source. First set the approximate coordinates of your image in the framing wizard (important!), then select File from the dropdown, then load your image. It will be plate-solved, and you can set that as target, along with knowing its rotation. Then, you can connect the manual rotator, start sequence with slew and center, and rotate the camera as instructed. Also, I will get to the flats wizard, but I have a confession to make... I have never used it, except to slew to Zenith! I take my flats the old fashioned way.... in the sequencer, estimating time per filter manually.

@@CuivTheLazyGeek Ahhh, thanks Cuiv. I figured there had to be a way.

All of your videos are great!! I'm binge watching :) About to go all in with NINA. Question... if I choose to autofocus with each filter change, would I still benefit from calculating and entering my filter offsets? Thank you!

@AF29007

Yes. For example, if you're switching from Luminance filter to Ha/Sii/Oiii filters, the offset is substantial and the stars may be so out of focus in the narrowband filters, the autofocus routine will crap itself. Having the offsets configured will allow you to get close enough on filter change that the autofocus routine has a chance at being near enough in focus to suceed.

Very helpful. I don't actually use filter offsets but I might start now. Here's a nice idea for a NINA feature. A filter offset calculator wizard. Somthing along the lines of first zeroing any existing offfset data, automatically performing the autofocus process on each filter x number of times and calculating the average position (prob Std Dev. too) for each, performing a sanity check and asking if this should be used to automatically populate the offset table.

Awesome as always Cuiv. Just a couple of comments/questions with regard to backlash and offsets with. In a previous video you had backlash set at 90 and then a later video it was set at 100. That is a 10 step difference and won't that affect the filter offsets if there is only a 3 step difference in some of them. I did the backlash calculator/function on my EAF with NINA and it determined 90-steps. Is that value that precise to use for filter offsets if they are less than 10 steps? I see you are getting more likes and subscribers. I think you are going 'explode' with subscribers soon. I get much more out of short videos rather than these long 45 minute videos where they spend too much time on the theory rather than 'just press this button'. - Cheers Kurt

Thank you! It was at 93 originally, in an earlier video I determined it was around 100, I have it at 95 right now and it seems to be working very well. For my focuser and scope, 5-10 steps is not a huge deal, but it really depends on your system and how your focus curve looks like. Ideally you want to be as precise as possible. As for the offsets, an offset of 4 steps could be huge on one system, and very small on another. It's all relative to the curve and wide it is in terms of focuser steps. For me, there is a significant difference between R and B for example, or HA and OIII - so when this changes it is quite significant. I'm kind of afraid of getting more subscribers!! I like being able to read an answer to the comments for example :)

Pretty useful for the new filter user! if I use overshoot method to compensate the backlash, whether the absolute focus position will change or not?

@CuivTheLazyGeek

Overshoot method will always overshoot and return if there is a movement in the overshoot direction - but if there is no change (offset = 0) it shouldn't move

Very informative videos. I have been using apt and moving over to N.I.N.A so these have a been a great help. I have also just moved over from a DSLR to a asi 183mc pro and i haven't used it yet. Hopefully you can help with my question. Shall I use the ascom driver for the camera in nina or just connect to the camera? This also brings up another question , how do I determine my offset and gain ? as the ascom driver has presets but when connecting strait to camera it dosnt. Hopefully you can help . Thank you

Congrats on your new camera! I would suggest using the ASCOM driver, setting Unity Gain, then click on Advanced - make a note of the Gain and Offset. Input those as is in NINA. This should be a good starting point.

Shouldn't you have removed the filter offsets before changing filters and running auto focus? Otherwise wouldn't the offsets improperly influence the focuser position? (Love your videos by the way!)

Eagle eye :) Yes, you are right - my offsets were mixed/improper because of this demonstration. I went back to my normal offsets off-camera :)

I just saw your very interesting video. Unfortunately this plugin will not install in my pc, I keep getting the message error Plug in installation for plug in filter offset calculator failed... I am running NINA 2.1 , pity... any idea?

Hi there! Thanks for this great video... have a question? So if my offset is let’s say 15390 for L and Red is 15405.. are you saying To only import the last three numbers in the offset tab? Or the full numbers? Thank you

@CuivTheLazyGeek

3 жыл бұрын

As long as the difference between the numbers is 15, anything works. So 0 for L and 15 for R is ok. 90 for L and 105 for R is on. 390 for L and 405 for R is ok. And 15390 and 15405 is ok. :-) The only thing that matters is whether the difference (e.g. the offset) is maintained!

Cuiv, The Lazy Geek thank you very much again 🔭

Last night when I connected the autofocuser it had position at zero. So I was lost because the telescope is never packed. It just travels like it was last used. So the focus wasn't all the way in, which is where I had it set as 0 (all the way in). I found focus again and I think I set the ascom driver to keep the last position as 18,xxx position where focus is close. So I lost the focus setting between the former session to last night. Are you saying here that you can set luminance to 18,xxx in the filter wheel section and then put the others to the focus position that makes them in focus, so they are all exact positions, not just relative? Also good idea on averaging the focus differences. I ran one on the OIII filter last night and the HFR from an actual sub was 4.08. I reran it based on the position of the 4.08 and the next sub HFR was 3.68.

You can put the absolute Focuser positions for best focus (averaged across multiple runs per filter if necessary) in the filter offset. NINA will always subtract them from one another to deduce the relative number. Otherwise I didn't quite get the position at zero. Did the driver reset its index? That can happen with some drivers, but not much NINA can do about it. However, the focus offsets (even when using absolute positions, since they're converted to relative) would not be affected by that. Good luck!

If I did not get it wrong, I do not need to set filter offsets, in case I focus manually, right? Thanks.

So if you have an electric focuser that you connect to the computer, and choose not to use autofocus for, offsets will still be useful: you could focus with a Bahtinov mask on one filter, and then the offsets would move your focuser by the correct amount each time you change the filter. However, if you do not have an electric focuser, then yes, filter offsets are not needed!
