Well done catching such an early sliver of a Moon.

Thanks for sharing. It will be intersting what comes from NEAF this year on this product and the price of course.

In my 'umble opinion this is all because so many SeeStars were sold that the karmic balance of the Universe was broken and attempted repairs have since run into serious problems. It's like the repairs to the A1(M) only taking longer. 😁

Hi, interesting post. As regards polar alignment you might consider taking advantage of the fov through one of your telescopes + camera pairings when in EQ mode and directly polar aligning using SharpCap Pro's (SCPro) polar alignment tool. SCPro does require a fov between I recall 0.5 to 5 degrees. If you are intending planetary/lunar/solar imaging just don't bother trying to make an EQ set up just go Alt-Az.

Good luck with whatever you decide to do.

Cheers,

Steve

HP laptop (Intel 7500U) with 16GB RAM and 1TB SSD. Use SharpCap Pro to capture DSO's and Deep Sky Stacker for stacking then StarTools to process. With lunar/solar data I capture with SharpCap Pro and then stack and process using AstroSurface.

Hi Ratlet, thanks for sharing how you got on last night. Agree about night time not  being good for resolving IT issues. 😬 Was the issue with the iPolar down to new software? I've not used mine for a long while now preferring SharpCap Pro's polar alignment tool.

The GEM28 is indeed a very quiet mount and am really glad you have found you can save money not having to get another mount for your 102ED.

I presently use a holster that came with my CG-5 to hold the hand controller of the GEM28 but you could have a nice business selling printed adapters for the iOptron. 👍

Here's to more clear sky nights ahead.

Cheers,

Steve

Hi, sorry to hear of your issues. You can safely deal with OneDrive in Win 10/11, more here-

Windows Updates are a constant source of bother, who'd have thought? It might pay you to turn off automatic updating to give you some breathing space to either check updates before manually installing the safe ones and avoid known issues at least for a month or so. 

The overriding issue with our hobby is that sometimes an astro-programme will require the latest Win updates to function.

AstroSurface will also stack and process .ser data.

Hi Cindy, pleased you have devised your own means of setting a good 'Zero Position' to begin sessions.

The GEM has four RA lock positions-the 'Zero Position', an 'East', 'West' and storage positions. The 'Zero Position 'is the one with counterweights pointing straight downwards, the 'East' and 'West' positions can be useful when you employ the iPolar or some other polar alignment tool that requires you to move the mount by 90 degrees. Now I've found that these three lock positions are more felt by the fingers than can be visually seen-when the rig is in just the right location (be it the 'Zero Position' 'East', or 'West' position the lock will fully engage. It feels like a definite engaging clunk. Maybe it was designed that way to be able to feel the right lock position at night in the dark (and after all the lock knobs and mount are all black coloured)? Let's call it an iOptron feature.

Rather envious of your conditions allowing you to actually get out and use your mount-enjoy!

Cheers,
Steve

Hi, thanks for your feedback on first using the GEM28, your results with such a big fl are especially very encouraging. As Elp mentions the axes are very sensitive to imbalance and its my suspicion the internals aren't symmetrical-the GEM28 has connections for an iGuider which I think helps balance things.

Enjoy what you have and I hope you have more clear nights to image and test things out. I did find moving from having to star align the mount to plate solving quickened the set up time and it can be done from indoors. Getting out under the stars can be good fun too.

Cheers,

Steve

Hi Cindy, thank you so much for your very kind post. Yes, it's usual to get rain after buying new astronomy equipment but hope that soon clears away so you can properly use the GEM28. I also hope you find this thread of continuing value-please do feel free to post any comments, successes, ideas if you can to help anyone else in the market and thinking of buying the mount. 

I haven't any personal experience in pairing the GEM28 with an iPad unfortunately and a lot of sleeps have passed since I looked into the wi-fi aspect of controlling the GEM back in October-November 2021.  When I first got the mount I did sucessfully try out all ways of controlling the GEM28 including wi-fi but that was to my laptop running Windows 10. subsequently I have moved to controlling the mount from indoors using USB over Ethernet which is very useful in the Winter. You likely know the wi-fi module for the GEM28 is located in the handset and is similar if not the same as iOptron's iStarFi adapter that other mounts have to add as a separate module. I think each owner finds the way that best suits their use of the mount and their circumstances and we amateurs are never afraid of trying out new things. 

Do let us know how you get on and we wish you clear and dark skies.

Cheers,
Steve

If IR is your thing what about the 462MM

Yes, there's a few cameras now with NIR ability. Wish I had enough ££ to buy more things. I recently also contacted ZWO regarding a future ASI678MM.

So no IR Cut filter?

Seems not.

Further to my recent post I've had confirmation from ZWO Support in the US confirming the ASI585MC-Pro comes with an AR cover slip.

Added 29.2.2024 13.44 PM-FLO now list the camera as having the AR slip cover/protection window-

Thanks ratlet and elp for helping answer Sathya's concern. 👍👍

Cheers,

Steve

Hi Sathya, thanks for your post. I've had the GEM28 for around 28-29 months now and apart from my recorded issue with the iPolar USB port the mount has performed well for me.  I haven't had any pointing problems, I use a combination of iCommander software and Stellarium to control slewing and both have worked fine. iCommander has the useful return to the Zero Position capability and Stellarium its useful planetarium. In addition I have used SharpCap Pro's 'go-to image' tool to slew to past positions to add extra data to targets.

I hope this account is helpful to you. Perhaps other contributors to this thread can give their views on the matter?

I can confirm the GEM28 is light enough to be readily moved into position each night.

Cheers,

Steve

I've enquired over whether the Pro version will have an anti-reflection cover slip like the uncooled version. No one is sure right now. I'd like to try out the sensor's NIR capability.

Hi Paul, thanks for your post. You will have been rightly pleased to capture those images of the eclipse. The hobby has moved on and despite the present costs is more affordable now to more people and technology has come on in leaps and bounds though it mostly involves a computer or more somewhere along the line. That can be either off-putting or an added interest to astronomy since it allows so much more. Sometimes I wonder how far removed we might get with the AI ability to make changes to images and if it crosses the invisible 'cheating line' of letting the technology produce something that isn't there (and would we know anyway?) but that's a whole other avenue and views will range over that.

There has lately been frustration over the poor weather, certainly in the UK it has dramatically curtailed the number of sessions possible. In response my hobby has diversified to include lunar and white light solar imaging on a shoe string using older gear repurposed to get me back under the sky. Pehaps the least affected by the weather is radio astrostonomy, the detection and recording of meteor trails, again using parts from DIY stores and a small software defined radio, but again it relies upon a computer to run. Others in the hobby instinctively go for their wallets and retail therapy which last a wee while until there's no dark, clear sky to image under.

You could still use your old photography gear and try to replicate under the coming eclipse-there's a lot more choice now. Alternatively you could watch the event on the Internet.

So to sum up I'm not frustrated by image processing or computers but by the weather. I do hope you can feel that you can return to this satisfying hobby out under the stars.

Cheers,
Steve

This is exactly what I find with mine.

It's still the best tracking mount I've ever owned.

Totally agree. With engaging the clutch knob its more feeling the knob is properly engaged rather than anything visual. Maybe that's helpful at night when its difficult to see. 

Cheers,

Steve

Hi, the RA clutch knob is meant to be either in the fully locked or loose position to let you move the payload in RA but you have to get the payload/counterweight just right before locking again else you can think the RA is properly locked but it isn't and there's some wobble.  You can feel if the counterweight is either pointed down to the ground or at 90 degrees to polar align with. If there's any play it's not properly in position. Hope this makes sense. Perhaps another way to explain it is the RA lock knob can sometimes lock but not be propetly locked giving rise to the wobble.

If the mount's RA is not properly locked it will throw out your mount's 'Zero Position'.

Cheers,

Steve

Also try a gain of 100 with the 533MC and a wee offset (brightness) and see how you go. Much lower Read Noise and DR around 12-bits-

Cheers,
Steve

Hi, thanks for posting your observations using the Pegasus unit. I have the smaller brother unit the Pocket Box Micro which has powered the whole rig-the GEM28, main camera (ASI533MM-Pro), two dew heaters (for Samyang lens and guide scope) and StarTech USB over Ethernet hub. The unit is powered by the Pegasus mains adapter that you also use. I check and record the number of Watt hours and Amp hours drawn during sessions and while obviously the amount of electricity used varies mainly due to the weather conditions the greatest draw I have recorded was of 114 WHr/8Ahr when the outside temperature was -2.3C this winter. You do see a slight increase in output during slewing but that is very a small part of a multi-hour imaging session. The Pegasus unit copes very well and is rock solid in output.

Cheers,
Steve

Thanks so much for making your site available. Have it bookmarked now. 👍

I can also vouch for the 4tronix remote version.
