  1. The third one is my favourite, it's absolutely surreal!! And Gavstar's shot shows the great potential of NV. Congratulations to all, especially those who put the great effort to do a sketch!!

    Refractor upgrade

    Thank you all for your advice. ED 120, is on it's way...
  3. The hexafoc focuser has a limited (normal to me) travel, and is equipped with 2 extension rings. You only have to play with them if you go from 1,25" to 2" diagonal, or ccd and I suspect it would reach focus with a binoviewer, if you take them off. Easy to screw, no problem,

    Same here. 0.5-0.6 seems to be the lower limit except for Luna.

    Stability of PA alignment

    Do you take the scope of the mount? If you do, then you apply changes to the cone error which you took into account if you drift-polar aligned in the first place.

    That's what I thought too. In theory, the telescope's max magnification is dependant on aperture and lens figuring, not focal length, so shorter focal length eyepiece it is! But the 150L is a whole inch more than the 120ed meaning 40-50x more mag. Or the better optics of the ed will outweigh that extra inch? My guess is that since the difference is only an inch, it will....won't it?

    The only thing that troubles me is the loss in focal length, where the bresser fracs have 1200mm and the ed120 has 900mm. I know it's better for imaging, but for visual, will I miss it?

    Refractor upgrade

    I consider my frac to be my main scope, my all rounder. Where for deep sky my other scopes are more capable combined with a ccd, I really enjoy the deep sky views, a 5-6" lens delivers. And of course it excells in planetary, doubles, clusters (compared to my other scopes). It will live on an Azeq5.

    Refractor upgrade

    Well, taking into account that the 127L will go to fund the upgrade, the budget stretches as far as a new 152L or second hand 120ed, so the total budget is £700 max.
  10. I have really enjoyed my bresser 127L for the past years. It's the hexafoc focuser version, and I was most satisfied by it's optics, the focuser and the overall build quality. I thought it would be a life scope, but as funds now permit, I started thinking of an upgrade. So... where should I go? Being so pleased by this achro, one choice would be the bresser 152L. But there is always that SW 120ed. What would you choose? It's the classic aperture vs quality dilemma.... P.S. I already own an ed80 for grab 'n go and A.P. and a bresser 150s newtonian for deep sky eaa style.

    The £5 wifi adapter

    I have plugged to the mains via an old 5v phone charger, so haven't tried with a battery. I 've used it only in AP mode, the wifi signal drops to half at about 10m, so it's signal is not very powerful, should have a working range of 15-20 meters but that's more than plenty for my intended use. The settings, once set, are saved even after power off. No field tries yet, just dry runs inside the house, checked in eq & Az mode, also with the aux encoders as push-to.

    The £5 wifi adapter

    Synscan pro android app & Skysafari settings. Download synscan pro app and go to settings. Tap 3 or 4 times the empty line between "wifi settings" and "help", and a hidden menu will appear. Go to "connect settings" and set Read timeout to 400ms, disable "find devices" and enter the fixed IP as "" Ok... you're good to go, click connect.(make sure you 've established connection to the module's network!) Then if you want to use Skysafari, go to settings, scope setup, make sure you 've got eq or az right, connect via wifi, and set : IPaddress & port 11882. That's it, clear skies.

    RS232 to WIFI

    The £5 wifi adapter

    Can it be done? Without any programming skills? Yes, it actually seems that way... THIS WAS TESTED ON AN SW AZEQ5 mount which communicates with the handcontroller on a 3.3V TTL LOGIC. CHECK YOUR MOUNT'S MANUAL FOR 3.3V compatibility (should be azeq5,azeq6,eq6rpro,eq8), although I suspect it will work with the other 5V TTL logic mounts since the DT-06 board appears to be 5V tolerant, but CAN'T CONFIRM Ingredients: - DT-06 Wireless Serial TTL WiFi board - RJ45 ethernet cable -5v power supply (or 4x1.2v AA batteries) First, take the ethernet cable and cut it in half. Strip the cables and identify the cables to the corresponding pins. Then I consulted SW azeq5's user manual hand control port's pinout. In my case the pinout is as follows: pin1: orange-white ---- ground pin2: orange ----not used pin3: green-white ----not used pin4: blue ---- ground pin5: blue-white ----mount Tx to controller Rx pin6: green ----mount Rx to controller Tx pin7: brown-white ----- +11 to+16 V pin8: brown ----- +11 to+16 V Then I connected the orange-white & blue cables to the DT-06 Wireless Serial TTL WiFi board's ground pin, the blue-white cable to the DT-06 Wireless Serial TTL WiFi board's Rx pin, the green cable to the DT-06 Wireless Serial TTL WiFi board's Tx pin, and a 5V power supply to the DT-06 Wireless Serial TTL WiFi board's ground & Vcc pins (or 4x1.2v AA batteries) , I 've ordered a buck stepdown converter to utilize the +11 to+16 V from pins 7&8 to power the module, but for now I just wanted to make sure it works! Now that the hardware connections are done, we move on to the settings. Power the module and a led will confirm it's on. It is on AP mode so scan with your phone for wifi, and you 'll see something like DoitWiFi_xxxx. Connect to it (no password was set on mine). Open your browser and type , this will take you to the Built-in WebServer where you set the parameters for the module. You will see three tabs: "status", "module", & "more" From the "module" tab's dropdown menu, select "serial" and enter the values : baud rate:9600, databits:8, parity: none, stopbits:1, serial split timeout : 200. Click save. From the "module" tab's dropdown menu, select "wifi". Here you can change the SSID name (I put Synscan), and set a password if you like (I don't). Click save. From the "module" tab's dropdown menu, select "networks". Change the "socket type" to UDP server, and assign UDPserver port to "11880". Click save. Then from the "more" tab's dropdown menu, select restart. Now you 'll have to re-join the network under the SSID name you 've given. I 've only encountered some connection problems related with the serial split timeout. I found a stable connection when I set it at 200ms at the module's Built-in WebServer, and 400ms as the Readtimeout on the synscan app. That's it, you 're set to go. Download synscan pro app and skysafari plus or pro and I 'll post the settings in those apps in my next post.

    sky-watcher az-gti eq mode

    The camera with it's lens doesn't weight much, so a standard SW dovetail should be sufficient and economic. The 21cm one, should give you enough length for proper balancing.
