Hi Laco, As an example, check out the options of TS - this one might do it for you: https://www.teleskop-express.de/shop/product_info.php/info/p9286_TS-Optics-custom-made-Adapter.html Allow me to emphasize to do the measuring by yourself, as there might be different versions of the series 5000. Your local shop might help you, and provide options. Best Regards Fabian

Hi Peter, (And all others suffering with the stock crayford focuser of the Meade 127 Series 5000 APO) Just wanted to let you know, I found another solution to replace the focuser on the telescope, no need to fully replace the M130x1 adapter from the OTA Tube. And you can keep the nice blue ring With loosening a small setscrew on the old focuser close to the blue ring for the finder scope, the actual focuser can be removed by rotation. The male thread used on the telescope side – at least on my version – is a M70x0,75. A caliper and a screw gauge is helpful. So, what I did is to order a customized adapter to match the M68x1 of the Baader Diamond Steeltrack std dovetail adapter. And with the adapter to be approx. 2cm in length, the focus travel should be quite similar to the old focuser. Glad this was working very well for me. It makes the 5” a very good scope again and I can now use it with autofocus for astrophotography. Have a good day and clear skies everyone. Fabian

Hi Peter, Many thanks for your detailed feedback! I have measured 130mm as well, pitch should be the same. I will check as well with my local astro-stores, if they can support me further on this project with a suitable adapter. Best Regards Fabian

Hi Peter, First of all, thanks a lot for sharing your experince regarding the focuser replacement! I have the same issues with the crayford focuser attached. I also plan to replace the focuser on my old 5" Meade Series 5000. Currently it is still a thought experiment. Before going ahead, the OTA male thread on your 127 is a 130M, 1 mm pitch thread? Thanks and best Regards Fabian
