If you need any images I have one you can use ... Its not special but it is our star and taken with amateur equipment, and an ameteur bloke 😀  

FLOIKI ... has a nice ring to it 🙂 good luck all !

Heads up ... The SAM app now dithers 👍

Finally had a chance to play with it , no imaging just watching guiding.

Wonder if any PHD gurus would take a look as I'm not really sure what the numbers mean.

PA was excellent according to Sharpcap but not so in PHD2. Wonder if it's because Polaris just clears my roof so pretty unsettled air where I'm polar aligning.

The wonky calibration is (I'm guessing) due to the mount not knowing where it was pointing as only PA'd and no star alignment.

Very slightly East heavy using finder guider

Comments gratefully received.

Lovely image, did you take this with your asi1600. ?

Cheers, yes the ASI 1600 mm ... Mono beginners luck !

Don't forget, mono doesn't always mean black and white ...

Various Photoshop methods of false colour can be used.

45 minutes in  90 second subs bottle 6 Ha filter mono.

I've dreaded (although understood the pros of mono) but am so glad I with it. This is easily the best image I have taken and only just started getting to grips with the new camera.

Good luck with your choice.

Well, it works 👍 guiding was a bit hit and miss but hopefully can be tweaked a bit ... Forgot to set up East heavy in my haste to see if it survived my surgery , Dec guiding spot on ( was reasonable before operation) Ra was up and down just above the 3 px mark on the graph.

Just spent 4 hours resurrecting my AVX mount, it had become so stuff in RA it just wouldn't track at all. Googled as much as I could find and used the http://rocketsparrow.blogspot.com/2017/01/how-i-made-better-celestron-avx.html?m=1 as a guide.

Decided to use a bearing as discussed in thread. I chose the https://simplybearings.co.uk/shop/p503131/32007-Premier-Budget-Metric-Single-Row-Taper-Roller-Bearing-35x62x18mm/product_info.html?backstep=1 as the dimensions were perfect ( almost perfect, bearing is 2mm too thick but works fine)

Cleaned all the gungy grease off and used thin layers of superlube.

It's so much smoother now and I can actually balance the mount.

Only problems I had were the 2 bolts that hold the RA and Dec assembly together stripped the mount ! Soft cast ally by the looks of it but there are 4 holes for 2 bolts (almost like Skywatcher knew 😂) and refitting the motor worm assembly is tedious to get backlash adjusted .

Can't wait to try it out.

Ps the new bearing wouldn't quite fit til I put the mount in the oven @ 80 degrees and the bearing in the freezer for 5 minutes.

Not bragging but mine is bright enough, it only needs to be dim really ... Just enough to show the reticule markings but not too bright to over power the stars.

Make sure it's proper dark when you use it.

?

Is there any identifying mark on  back, maybe AliExpress would have it ?

Top job David

Why not use UK Astro buy and sell ... No fees from Mr eBay and you might find a CPC 800 or similar on there .

I'm sure they will   so, is there any alternative to lynx adapter so i can rotate my camera?   Also if i am going to use the lynx m48 , how i m going to use a 2" filter?

If you look back through the thread there is discussion of using the small screws in the t adaptor to make a virtually free rotator.

Not too sure but I think the focuser is rotatable for framing when imaging.

Hello, i am about to order the 72ed to use it primarily for astrophotography with my 450d. I choosed to match it with the ovl ff and the lynx m48 adapter.  I asked FLO if there is any other option so i will be able to rotate the camera for framming and they told me about  this extension tube.

https://www.firstlightoptics.com/adapters/moonlite-15-focus-extension-tube.html

I thought that my goal was to be closer to drawtube and not going further.

What is your opinion? 

They're great and they will look after you ?

Don't forget it can be used in EQ mode (beta firmware on SW website) as well !

Weird, I'll check my settings tomorrow

Did you check the connection type in settings  - connect settings - choose network, mine was on serial.

Can't comment on your set up but I use the app on my Win 10 laptop to connect to AZ-Gti with no probs so it can work.

Check the connection type in settings  - connect settings - choose network

Old thread but heads up, the Android app has just been updated.

Spent so much time faffing with this , I'm going to use a smaller sensor (183C)

Maybe try again later on

Old thread dig up alert ! So if my filter is 6mm thick, the glass being 3 mm ... Would I add 1 mm to the target distance and include the 6 mm in the distance ?

So the total would be the same as adding a 5 mm spacer ?

Hi, well I hope you can get it sorted. weather is going to be a pain for the next few weeks. think ill be going for TS one if you dont have any luck.

All the best. Andy

Had another try last night , just over 69mm not good at edges ? might be the reducer ? it was never brilliant on the WO ZS71, might have to go another route

Have to add, my 'glorified SLR lens' was meant tongue in cheek , it would look beautiful on my black and red star adventurer mini !

... Must resist

It's a glorified SLR camera lens ?
