EdgeHD8
This is the stock standard Celestron EdgeHD800 with a Celestron 0.7 reducer

The dew shield is the Astrozap Flexi-heat with the build in heat belt

The mount is an original version 1 EQ6 with the Rowan Conversion, Astro baby tune up including new SKF bearings,delrim shims, new PC-board and replaced worm gear on my DEC axis. I have also replaced all the adjustment knobs with the nice big ones.

There is a Polemaster camera attached to the front of the mount. I use Sharpcap with the Polemaster to do polar alignment when needed. Seems to be quicker than the Polemaster software.

The bracket on top of Edge is extruded aluminium T-Slots on 3D printed blocks connected to Primalucelab blocks. Minimal weight is the main reason for this setup over the normal PrimaLuceLab bracket that I have. The setup also keeps weight close to the scope and makes it very easy to install a guidescope on top as well. My guidescope is on a custom 3D printed bracket that just slides in and are locked into place using T-Lock screws.

The NUC PC runs all my software and also acts as USB hub. This is connected to the T-Slots with a custom 3D printed bracket and T-lock screws. Software on there is Windows 10 Pro, Sequence Generator Pro, PHD2, Sharpcap, Cartes Du Ciel and ASICAP from ZWO. Files are saved to my Dropbox account so no need to do any transfers of data in the morning.

The power distribution and dew controller box is a DIY version, also 3D printed with a dedicated fuse per supply line, reverse polarity protection. This is also connected to the V-Slots with T-lock screws. The box gets power from a 12V 105 A/H battery that is on a charger all the time. The battery acts as a nice UPS during any power outages. I easily get 6 hours of imaging on battery power only. I use a TX60 connector to connect power from the battery to the box.

There is a ZWO 7 slot 31mm EFI Auto filter wheel. I have all Astrodon filters in there. Ha 5nm, OIII 3nm, SII 5nm and then normal LRGB E type. I originally bought the ZWO filters. Was a waste of money. Stay away from those. The filter wheel however has been working flawlessly since the day I got it.

Camera is a ZWO ASI-1600 Mono. Not the pro version. I bought this two weeks before the pro was released. Still pissed of with ZWO that they did not tell me to wait two weeks. I have replaced the fan and the fan wire mesh. The fan wire soldering corroded and it was just easier to replace than to try and fix or sent back to ZWO. The chrome wire fence was also corroded beyond looking good. Overall the ASI1600 was amazing value for money.

The Off Axis Guider (OAG) is the one from ZWO. Has been working well but had to do a few minor mods (better screws) to get it to be stable.

The guide camera is a Lodestar X2. Been working perfect since the day I bought it.

USB cables are all Lindy and are either Cromo or better. Never had a days issues with these
