    I’m a beginner and purchased a C8 with AVX bundle on sale last June. Now I want to try some imaging so I purchased an ASIAir Plus. I’ve been having Go To issues with ASIAir but don’t know if it’s due to AVX but have a new start up procedure I’m testing. First night with this procedure was successful but need more sessions to verify. ASIAir has been more of a problem than the AVX. Next step is to add guiding and I’m going to use a Celestron OAG and ASI174MM Mini. I’ve only got a Nikon D5100 for DSO, but purchased a ASI585MC for planets but I’ve taken a few shots with it objects like M27, M33. I’ll stick with the AVX until I out grow it and it proves unable to handle more complex projects. I’m retired so I’ve got the time to tinker. Thanks for the review.

      Just started using a Celestron OAG. The guiding now allows me to use longer exposures. I've tested up to 5 minutes and the stars appear round. Practicing on Horsehead Nebula without any filters yet. Unfortunately, the ASIAir Plus 256 I'm using gives me mount disconnects whenever I'm guiding and imaging. I can't even go an hour. Working with ZWO.

    Hi James, I am so pleased to see this post. As I watched it I thought am I seeing myself here?
    I took up the hobby about 3 years ago and the AVX was the first EQ mount I purchased along with a Sharpstar 76EDPH scope and have had exactly the same experience as you and basically arrived at the same conclusions as you do, for the same reasons.
    I now use an AM5 and ASIAIR Plus for deep sky imaging (2 actually).
    I am keeping the AVX for Lunar and planetary
    Congratulations on a very thoughtful contribution

    Thanks for the post I really appreciate the verification of what I have experienced. My AVX has been okay but I agree that it is subject to odd wanderings once and a while. It does take a long time to recover from dithers and at least 15 minutes after a Meridian Flip. All that said I love it, I have learned a ton using it and I gotten some very good results in spite of it's quirks. I am ready to spend some more $$$ on a better mount to host my C8 and my AT72EDII will continue to ride on the AVX.

    The AVX was my first mount and I admit I had problems at first. Mine is very capable of great guiding. It wasn't always the case though. I now use a mini PC with CPWI, N.I.N.A., and the star sense auto guider. With that setup I get just as good of guiding as my EQ6r pro. Main thing I've found is don't overload it. Mine came with an 8" Newtonian that, in my opinion, was way to heavy for photography, even though it was marketed as such. With my Redcat 71/QHY183 setup it does great at 5min exposures. One issue I still have is you have to remember the combination to plug in and turn on everything or CPWI will give you issues connecting to it. I wasted quite a bit of time to figure that out...........

    Interesting review James I gave away an AVX & the new owner tinkered with it for hours but never managed to get it to work properly, the handset control setting up & used for visual it's a great mount but other than that for astrophotography it was poor. The old CGE pro I have in the observatory was Celestron's flagship mount & while mechanically it's pretty good the electronics have always failed on these. Mine was dead when I got it with the RASA & I nearly threw it as it just got in the way but after fitting the ONstep kit it's totally transformed the mount. Although if I could have afforded an EQ8 that would be in the observatory.

    • @DSOImager
      @DSOImager  ปีที่แล้ว +1

      Thanks Tich! Celestron just doesn't seem to have a solid mount available for astrophotography. It feels like astrophotography was tacked on as an after thought. The whole mount line up seems focused on visual. It's surprising given the astrophotography focused scopes (Edge/Rasa)they have.

    • @dumpydalekobservatory
      @dumpydalekobservatory ปีที่แล้ว

      I agree James for some reason Celestron use servo motors on the CGE & probably all their mounts which aren't the most reliable, the onstep kit I have on it now uses stepper motors which a far more superior in my opinion.

  • @davidstearn1342

    I bought my AVX as a package with the C8 in December of 2022 along with the Hyperstar 8, 533MC Pro and the ASIair Plus and EAF.
    Back then the AM5 was making its debut.
    So far I have been pleased with the AVX. I just started guiding with the Askar guide scope and ASI 174 mm.
    My guiding has improved and I find that if I have a good Polar alignment and the rig is balanced that the guiding is more consistent although I have noticed that the RMS is not consistent.
    My next step is to move the image train to the back with an OAG and SCT reducer. Once I master that I will look at upgrading my mount to an AM5 or 3.
    I figure that when ZWO comes with revised models of the AM series the AM3 and AM5 will go down in price.

    I gave up on mine. Keeping it for planetary and moon but bought AM5. After 2 dismantles and addition of an extra bearing (see Jason Burn's excellent video AVX build tutorial) still poor guiding. On the plus side I am now more than comfortable with the ins and outs of guiding thanks to much reading and adjusting every setting on ASIair for the AVX. The AM5 just does it and when time is precious with few opportunities for imaging I feel it was worth the expense.

    @KJRitch 2 หลายเดือนก่อน

    10 months ago I posted , further down this comment list, my new experience with my AVX and ASIAir. I have a C8. Since then I stopped using the ASIAir and moved to NINA on a Mele Quieter 3Q minipc. No more mount disconnects or GoTo issues. I've been able to concentrate on improving the guiding using the Celstron OAG with ASI174mm mini guide camera. I switched from Hysterisis to Predictive PEC algorithm in PHD2. I've also played around with adjusting the DEC and RA worm gear backlash. Of course trying to remove the RA motor cover I ended up breaking it at the narrow part but now its easy to take off and the break is down underneath where it's not visible. Between those two changes the guiding has gotten better and over time I can now get RMS total averages under 1" However, DEC still spikes. It will be at 0.5 then suddenly it goes up to 2" then come down. I don't bother to dither. I put the RMS error for each sub in the title so I can pick out the bad frames easily but I'll still go through all of them., I've been able to shoot 10 minute frames as a test. I use a ASI071MC Pro OSC so I don't shoot beyond 5 minute frames. If I could figure out how to flatten out the DEC spikes it would make my guiding a lot better.
    I've been thinking of upgrading but I feel the AVX is now running good enough. If I knew what I know now I would've probably gone with the HEQ5. It's an entry mount but its uses bearings on both axes while AVX uses bushings on the DEC. There is also a belt kit you can purchase to upgrade the HEQ5 and the bearings are easy to replace. A better tinker's mount.
    Now, I'm contemplating iOptron, AM5N, Losmandy GM811. The EQ6 head is just too heavy. I have to set up and tear down every session. I'm kinda wary of ZWO. It took 6 months for the issues I had between the ASIAir and AVX to get corrected. I don't think their customer service process is very good.. I also wonder how well long focal lengths work on strain wave mounts.
    iOptron CEM40 and GEM45 seem to suffer from some issues looking at threads on Cloudy nights. I just let the iOptron sale expire, now I have to wait another year. I couldn't get my self to pull the trigger.
    Losmany seems to be a good mount but there isn't much activity of the forums from users. I'd like more information on the guiding with SCTS with this mount. It's the most expensive of my choices but if it's my last mount it may be worth it in the long run.
    Thanks

      @DSOImager  2 หลายเดือนก่อน

      Good to hear you have your AVX dialed in.
      I think ZWO's customer support is hit or miss. I considered a losmandy mount a couple of times but they have a reputation of being a tinkerers mount and tinkering is something I am just not interested in. I have known a couple of people that used G11's for a bit and found that they struggled to yield good results with 11" Edge's. The losmandys were traded in for AP mounts.
      That's another option, a used AP mount.

      Interesting events happened about software. It was behaving as you described and additionally, it didn’t want to park scope. Eventually, I called to Celestron with complaint. Technical support person sent me some version of CIPW that fixed everything. Amazingly, main site of Celestron still doesn’t have this version, despite more than 1 year past. Moreover, besides software problem, it is clear where is problem. Problems are in bearings and lubrication. It doesn’t cost a lot to fix it. I just wonder why they don’t. It really cost nothing. I understand that bearings are USA made, but still.

    yup my AS-GT does all of that ...
    sometimes resetting is the only option
    I found that after a consistent tune-up it became flawless for about a quarter of the sky... I'm consistently getting 0.4 RMS for about three hours with 0.5 secs guiding which is why I haven't sold it yet... and I'm using that quarter of the sky (no obstructions )
    I have my C11 up on it at the moment for planetary work and it handles it ok ...
    as far as using a C11 on it for long exposure... not without a further 2k investment in the hyperstar... oh ... focusing the C11 is frustrating on the AS-GT mount...
    every 3-4 minutes it does go into a spike but I only take 60-90 secs exposures ... Bortle 8-9 here ... 17.9 sqm

    thanks for this. I am just setting out in astrophotography and I'm still in two minds. It is very frustrating I agree but then it has forced me to make the effort to spend hours on the internet and reading learning how to hopefully rectify it's shortcomings. Clear nights are few and far between here so I do forget some of what I've learned or my enthusiasm wanes between opportunities. At the moment I am still at the stage of trying different settings (I use ASIair rather than PHD2) and just recently learnt that AVX requires short exposure times for guiding. Although I promised myself and my wife I wasn't going to continue to throw money at the problem (ie buy an AM3) if I am happy I can do no more tinkering with the mount (already dismantled, re greased and adjusted gears) then I just might.

    Are you able to get PHD2 to perform a successfully calibration on your AVX? Mine rarely does. The orthogonal graph is ususall off from 90° and it complains about excessive backlash. Guding Assistant isn't able to measure the backlash. I've decided to try to use the last calibration settings and it doesn't seem to make any difference as when I spend the time calibrating. I don't bother with Guiding Assistant anymore.

    I have a totally different experience and do not agree with your conclussions.
    I have an AVX that I purchased last year (2023). I have an Edge HD 8 mounted on it. I use a HyperStar, an ASI183MM'pro with a filter drawer, an ASAIR Plus 256 GB, an ASI220mm guide camera, the Celestton GPS SkyAlign, along with the PLL Alto and Giotto, and the StarSense.
    I have had no issues with it tracking. It does a maervelous job. I ran into some of the issues you mentioned, and it was the ASAIR Plus. The problem was that whenever I entered into the ASAIR from my tablet, it was getting the wrong location coordinates, even when I manually entered the correct ones before connecting. Now I enteer frm my phone, which has the right coordinates, and since, it works beautifully and at the end, it parks my mount at the home position. There is a video from Astrobender on the process to get it right with ASAIR, and he is gott it right.
    When I use it with the Eagle5 and using NINA and CPI, I use the StarSense Autoguider and have zero issues. It guides and moves smoothly. I take exposures anywhere from 30 to 120 seconds long, depending on the target, and rarely have to discard shots (most of the time, it is because shooting stars or the police chopper just getting in the way).
    Lastly, you can set RA limits in the mount via the hand controller or via CPWI.

      Good to hear that your AVX is working for you. Running hyperstar and keeping the subs short certainly helps. Also good to hear about the mount limits. Does it hold those values after being powered off and unplugged or do they need to be entered everytime at start up? I imagine CPWI would hold on to it.
      I do stand by my conclusions. We can agree to disagree :) Clear skies!
