After discovering a periodic signal (once every 11 seconds) in my guiding in the RA axis I did a bit of digging and found the motor pinion rotates 1 rev/11 sec at sidereal rate. By motor pinion I don't mean the big brass spur gear visible with you take the cover off... I mean the output from the motor before the reduction gearbox. When I spin the motor at a fast speed you can easily see that the pinion wobbles about which is not a good thing. The pinion is simply hammered onto the somewhat thin drive shaft rather than held in place by a grub screw. Dec motor wobbles the sa

Took my Celestron AVX Mount out this afternoon to familiarize my self with it in the daylight. Wasn’t sure if or how it would work, since it’s my first goto Mount. I got it setup per the directions and attached the SkySync GPS. It locked on my location very quickly so I did the Quick Align option just as a test. The polar scope was oriented north, and I used Sky Safari to locate stars I couldn’t see cause it was daytime. My first choice was Sirius and it slewed right around to what should be the general vicinity! I then chose Venus in the West and off it went! I hit home and it went back to t

Hi guys, Having had difficulty in aligning and never actually managing to get my AVX to track to the standard I know it can, is the Celestron StarSense gadget the answer? I know I can align my scope accurately if I put the effort in and having moved last year I’ve been unable to have my mount fixed on a pier so I’m seriously considering this piece of kit as an easier way to align and to motivate me to get out more often. Please share your thoughts..... Adaaam75

I have just had my Celestron AVX mount back from Dark Frame Optics (DFO) after a hypertune. Has anyone else had their AVX mount tuned by DFO and would be happy to share their data? I have a C8, 6.3 focal reducer with DSLR camera on the back so I would be keen to know what the maximum exposure time I can expect for both unguided and guided with my set up? I have seen conflicting answers from various sources. I don't think 10 minutes unguided is possible with a C8, maybe with a lighter OTA or DSLR with lens attached. Thank you

I spent a fair amount of Wednesday afternoon centering my polar scope... Little did I realise that the polar scope requires centering before you even attempt perfect polar alignment. It appears that my AVX has been very forgiving in the fact that in the past I have more or less just got polaris somewhere near the centre of the circle before aligning. However, after watching many YouTube clips on how to centre the polar scope I finally achieved my aim in having the polar scope centered. Last night was my first serious attempt at 'Bang on' polar alignment with a well centered polar scope!!

Dusted off the scope last night to check if everything is working ok, aimed for a quick bash at Jove, then some fiddling with the OAG setup using M13 as target. Attached is Jupiter at around 1030 with Io bottom left. I was quite pleased as only had 2 runs of 3 minutes before moving onto the guiding practice which went 'badly'

Celestron AVX mount - How to fix tight RA / Dec axis
ChrisEll posted a topic in Discussions - Mounts
Here's a quick guide to adjusting the tightness on the Dec and RA axes on the AVX mount. Freeing up the axes means better guiding, less wear on gears and motors (some gears in the drivetrain are plastic), lower worm PE and you will be able to balance more precisely. Dec axis: Remove the counterweight bar and cup to reveal the tension ring. To adjust this first loosen the 2 grub screws at its side... there is a small access hole at the side of the housing. You'll need a tiny allen key to do this. Then use a slightly larger, stiffer allen key and insert this into the access hole and a -

Help with AVX troubleshooting
Ottawa Ken posted a topic in Getting Started Equipment Help and Advice
Hello, I was wondering if anyone could help with an autoguiding problem. I have a Celestron AVX mount. I cannot get it to guide at all externally. It moves fine from the handset. I have tried guiding from FireCapture, PHD2 (both auto and just manually guiding) I have tried to connect via the USB to Handset, and via the autoguide port (via my ASI290mc). I know the handset port communicates (on COM4) because I flashed the Celestron Firmware. I am beginning to think I have a tech support problem, but I want to rule out errors on my part. Thanks, Long time l -

Hi guys, Okay so I have a few questions regarding my AVX mount that have basically generated from me reading up on setting up my mount. Please don’t think I’m lazy, I have read up a lot regarding my new mount (hence the questions) and learned a lot so far but as I’ve only had the mount a week and due to work and time constraints I have been unable to do any more than literally unpack the mount and put it together. I should mention it took 30 minutes to flatten all the cardboard ready for Mr Recycling Man but the more packaging the better so no complaints there at all!! So, my questio

Hi there, may be a silly question that has been answered many times before. I have been in astronomy for over 35 years. I have a celestron 9.25 SCT on an AVX mount (my first goto which I bought in march this year) , i think the mount is great in that it is portable, and pretty sturdy, but it loses alignment after a couple of hours (and its a pain sometimes to get it aligned also for some reason, the keypad spews garbage at times, so I reset). Anyone else found this problem, and is it worth upgrading to a cgemii, or something like a CGX, or maybe an EQ6 if its suitable ? I am a v

Hi guys. Recently I had the opportunity to restart my hobby with a short astro-imaging test run in the back yard - a nice quiet little playground actually, near the place where I live. My setup consists of an eq mount (AVX), a dslr (EOS 550D), and either a classical M42 manual focus photo lens (anywhere from a Takumar 35 to a Tair3S 300mm, sometimes aided by a 1.5x or a 2x TC), or an ED refractor (C80) most of the time reduced with a 0.8x FF/FR. Since the area where my observing spot is falls within a +5 NELM around Zenith, I always use a LP filter (IDAS LPS P2 2", or Optolong CLS 1.

My AVX mount is having some issues, and I'm currently working with my retailer to resolve them. I'm curious though if anyone else is aware of similar issues to what I'm seeing? Sometimes during a long slew, the mount "hiccups" as the slew gets momentarily interrupted then continues, with some inaccuracies in slews after this occurs. After a higher-speed slew, the mount starts making ticking noises, that match when the worm spur gear appears to repeatedly jerk as the drive is being taken up for normal tracking - as if the worm is sticking somehow. The motor spur gear has maybe

I can confirm that there are issues with connecting via serial to the Nexstar+ handset on the AVX mount with the latest firmware . I'm currently trying to guarantee the behaviour process I'm seeing but it's intermittent and that is annoying when trying to troubleshoot. I'm having problems in getting repeatability of the issues being seen, but this is the most consistent behaviour I'm getting. The behaviour I'm seeing is: With everything powered off, I connect up the cables between my SkyFi and the handset. I put the handset in the cradle so it doesn't move. I've previously modified the -
Hi. In preperation for a remote box-observatory i have been setting up a pc for telescope controll and more. I now have Kubuntu working with a ssh tunnel and headless vnc setup. KStars is installed with all necesarry drivers for my celestron avx, eos 550d and orion autoguider. Everything starts up in KStars and i have controll over all the exuiptment, except! The issue. 1. When slewing to an object using the nextstar hc on the mount: Recticle in KStars moves in the same path as the telescope, and ends up at desired target. 2. When slewing to a RA/DEC coordinate in INDI control panel -> Eq.C

Hi After selling all my equipment some time ago I have now started the hobby again with a C925 on an AVX mount. Last night was my first chance to try out the Starsense Accessory, which seemed to work quite well. However I was a bit concerned that when doing the calibration for the SSA camera position and during the Polar Alignment routine the tracking seemed very jerky at higher magnifications. The video I took of Jupiter after alignment did not seem to show this (although poor in all other ways) so I don't know if the jerkiness is something to do with tracking mode used by the SSA han

Hi, I have a Celestron AVX mount that has developed a minor fault. In cold weather (e.g. winter nights) the RS232 port on the Nexstar+ handset does not function correctly. If I connect to it via the ASCOM driver it will function for a minute or two and then stop replying to commands and so locks up my controlling application. I’ve looked at the ASCOM logs and can see a command being sent but no reply and then the controlling application retrying the command. I have tried replacing my USB to RS232 converter and also tried NexRemote (which has a similar problem with communicating to the han

Hi Everyone, Just wanted to post my experiences with the Celestron AVX+Advanced GT and Celestron's Firmware Manager (CFM) - Specifically Boot Loader Errors I've used Celestron's Advanced GT Mount for a few years and only had a Boot Loader error once. The Good people at FLO re-flashed my handset and away I went. Happy camper Before getting in touch with FLO, I tried desperately for days to try and re-flash myself (I've worked as an IT hardware repair technician for years so i'm not an id10T but I am certainly no programmer/software engineer). I used probably every version

I have a Nexstar+ handset on my AVX and despite reading the manual and scrolling through the options; I cannot find where to search by entering RA & Dec on the handset. Mostly I have been using the Deepsky and Stars sub headings to enter SAO, search Messiers etc but can't find search by RA & Dec can you help please? I can see that you can enter and save targets in User objects by entering and saving RA & Dec... It could be me suffering a sleepy head??

Hi there, I'm looking for an extension tube to put on top of my Tripod. It's an AVX Tripod, but I won't be using it with an AVX head; it'll be used with a Giro Ercole mount. Both the Tripod and the Ercole Mount have 3/8" threads on the connector. I know it's difficult to get an extension to which the AVX mount itself will fit, because it requires a North peg in a different location from the usual Skywatcher types, but that's not an issue here as I'm attaching a Giro mount, which as far as I can tell does not require a North peg, but tell me if I'm wrong. All I really need is -
Noticing a break in the cloud late evening on my 'Weather Channel' app; I decided to practice my new polar alignment skills on my wonderful sturdy AVX mount. Armed with my weapon of choice - the sensational Altair Starwave 102 F/11 Achro Frac which never fails to give me crystal clear and colourful views, I made my way onto the lush green grass of my girlfriends reasonable dark, edge of town garden lawn. It's fair to say that when I started it was very cloudy and it proved quite entertaining trying to catch alignment stars teasing me by peeping out between the white stuff. Last week

Here's a thing, I have a beautiful condition AVX and have been looking at the amount of weight she will take.... 30lbs 13.6kg (although there was a view 35lbs from somewhere I read) I just weighed my 150 Frac and without EP, Diagonal and Telrad it's coming up 9.8kg ... that leaves me 3.8kg for counterweight mmm I take it the load of the mount is scope plus counterweights? I think I might need a bigger boat????

Hey guys, First post here. I received my AVX mount 2 days ago, and on my second night I finally got the Go-To and tracking right. First night the controller didn't ask my for location info, and I didn't input location by overriding the preset. I was doing some visual observing, and then decided to photograph Alberio. For that I had to remove my eyepiece and attach my camera. And because the mount is ALWAYS tracking (what ever it is pointed at), the motors are running, and I was worried to put even slight pressure on the tube while tightening the t-adapter. Is it ok to put sli
