that’s great info thanks! I can confirm this one works fine over Wi-Fi, ip address and port 9999 as you say. You can go direct to the built-in web server or SkySafari. Prefer SkySafari as the units own web server is a bit clunky for my liking. Bluetooth is ok from the android phone but not from an iPhone.

Hi Skybadger, Are you using the native onstep app or are going through something like SkySafari on your android device? I got hold of an old android phone but although I can run the onstep app fine, apparently the android version is too old to run stellarium+ and I’m too tight to buy SkySafari again! need to learn about android….. Out of interest, what implementation of onstep are you using? cheers andrew

also worth noting that I used the company's live chat feature late last night to ask a technical question, and while I didn't get an immediate answer, I did receive an email reply by the time I woke up this morning. Good english and a reasonable reply.

Yes Luminance frames. Are they really that necessary? You say "if" you want to take them, I've sort of assumed that you had to, but maybe not? Have to admit occaisonally I've captured LRGBHS and O for an object and the combined image is better without the L.

your images are a tour-de-force! maybe I will go doublet.......

Got the usb working, didn’t push the usb in far enough!! Doh. ascom all connected nicely. APT can slew it around, as can stellarium. pointing looks about right although can’t be sure as inside due to force 8 winds and rain outside!!!! (Again) put the c8 on with the counterweights and still slews just as good, fast and quiet. Movie shows slewing from m31 over to Arcturus. IMG_3471.mov

I was wondering about this...... You buy a fab APO so you don't get colour disortion (blue fringes etc) when doing visual. And this is because the different colours have slightly different focus points. i.e. when the red is in focus, the blue is slightly out of focus. (this maybe completely wrong in which case the rest of this is misled) So if I'm using a mono camera with automated focussing, can I get a not-so-amazing scope (maybe trade some more aperture for less colour correction) and as long as I set the image aquistion software to focus on change of filter, I should be all good? (thinking I could sell my AA Wave80 Super ED triplet and get a AA 125 EDF as these seem to go for the same (ish) and be none-the-worse off? Any thoughts? Andrew

Slewing with onstep under SkySafari on iPad control. A decent rate I think. slewing using the arrow buttons on SkySafari seems a bit slower. I think from the documentation that the android onstep app might be more flexible but it only runs on android and I don’t have an android phone (going to buy a cheap one and see what happens) haven’t managed to get the usb connection from my windows pc working yet. l IMG_3458.mov

Hi All, Bought one of these to see what it's like and how it will work. I bought the "lite" version: https://www.terransindustry.com/en-gb/collections/onstep-v4-kit/products/celestron-cg4?variant=42563771302081 and it cost me GBP 119.70 all in (paid via paypal) after the introductory 10% discount was applied. It took about 4 weeks to arrive, no import duties or the like. Very easy to install although needed a bit of figuring out which bolts/washers/nuts to use where and the lack of covers for the motors isn't very pretty imho. I'm still in the process of configuring it up, so far I've got SkySafari on my ipad connected to it over wifi and slewing around works well, although all indoors at the moment as terrible weather! Still working on it from a star alignment point of view, but will need a clear night for that. Slewing is really really quiet. I intend to get it connected to my windows laptop when time allows and also to see how it works with guiding. Will update this when have more info. cheers Andrew

that's fab! thanks for sharing.

yes, it's a fascinating target for sure. and thank you, got a way to go yet though i think!! hahah

hi and thanks! it's bortle 4 where I am (according to "clear outside"). The RASA8 looks like a beast - is that a cropped image you have posted there?

thanks! I did try some 5 min subs in there as well. but i thought the deal with cmos cameras was sub length didn't matter too much and to use the sharpcap method to work it out, playing off manageability of lots of files with accuracy of the mount. 84 hours! bravo for sticking with it!!!!

Hi there, Took the opportunity to point the scope at the Squid earlier in the summer where there were lots of clears nights. Decided to go all out for Oiii and gathered 33 hours of 3 min subs. Using an AA wave80 scope and an AA183MM with an Optolong 6.5nm Oiii filter. When I stack it all in APP, I get virtually nothing, it's there but so so faint! Help! I know it's a faint target but I would have thought that much time would get something reasonable. Any ideas would be really appreciated. Duff filter? I've seen another thread about this today and it prompted me to ask this question...... Quite prepared for the issue to be something I'm doing though! I've attached the stacked FITS files for Oiii (and Ha for interest). regards Andrew Squid_June_2023-Oiii-session_1-1.fits Squid_June_2023-Ha-session_1-1.fits

i'll be chipping in to that, love APT and love the direct involvement you can have with the people who run it.

Hi, Here's Sadr and the associated clouds. RGB about 20 mins each. Ha, Oiii and Sii about 2.5 hours each. Taken with an AA wave 80 and 183MMTec. All 3 min subs. Also took an hour of L subs but the composite image seemed to get worse (washed out) when I added them to the mix. Yet to figure that one out????

yep all valid points, but worth knowing it's out there...(or maybe it will might be out there!!)

People might be interested to read about this new project being launched on kickstarter by Stuart Semple, activist artist(!). The aim is to replicate adobe CS and make it rent-free with lifetime upgrades included. Stick it to the man! https://www.kickstarter.com/projects/culturehustle/abode-a-suite-of-world-class-design-and-photography-tools I don't know if it will work or get its ass sued off but Mr Semple is a bit of a legend and worth checking out.

thank you! £5 on ebay, see how it goes! 🙂

think may have found the culprit!

"One for the price of Two!" in a similar vein to the earlier Cosmic Horseshoe pic, here's the gravitationally lensed Twin Quasar near NGC3079 in Ursa Major. 150 mins of L with 15 mins each of RGB using a Altair Astro Wave 80. This one is only 8.7 GLyr away!

hi another question...... If the fan is duff then I get why the fan light doesn't come on. But would that stop the TEC light coming as well though? thanks in advance Andrew

thank you, i bought it second-hand about 14 months ago, so not too sure. might have a look at the fan......

thank you, I may well have a quick look inside......

thank you, i have raised a ticket with Altair to see what they might have to say. and yes going back for repair may be on the cards!
