  • M42 – New ES APO 80mm.


  • Cottenham, Cambridgeshire, UK
  • Class 4 bottle


So my shares have vested and I’ve splurged on a new ES APO 80mm. Bit of a bodge job getting the guide scope shoe replaced since the spacing is wrong for the mounting bracket but good enough for now.

Short summary here: “It’s brilliant!” As advertised, nice sharp stars, Crawford focuser is nice. Basically a joy to use.

Ran a set of one minute subs and some individual exposures just to try it out. Managed a 10 minute guided exposure (which for my rig is good).



M42 ES APO 80mm – f/6. GPCAM – 10 minute exposure half gain. Some post processing with GIMP 2.10
