    The secondary has a 48mm secondary axis. Anyway I have shared a season with refractor colleagues with a 100% humidity beside a river and whereas they had their dew strips at 100% power, mine one was absolutely dry with camping mat outside the tube and some flocking inside.

    M34 from last weekend very close to Madrid outskirts, I could save only 25 subs of 60s taken between the clouds. Nothing brilliant indeed but another Messier to the count.

    Masked stretch preserves colors better, but it creates donuts and artifacts around big stars. I have found it is best to mix with Pixel math (In Pixinsight) a 70% fro Histogram transformation and a 30% from Masked Strech. After playing with masks you can increase the saturation on the nebula and dark the background. Cheers.

    A reprocess around M8 taken last summer, bad weather has one con, to read and test a lot around Pix.

    Latest tunning. The scope cover was broken, so a friend made me one with his 3d printer.

    Well should it be for both characteristics. The problem is that in order to get the same stiffness from CF than for a 1mm thick stell tube, you need around 5-8mm, what means several CF layers with the appropiate fiber orientation. Thermal properties and gradients are of course important, but I have been with the SW130PDS around -10C starting from 15C and if you use camping mat around the tube you won´t have to refocus in a 5h session. So invest 300 pounds in CF for a SW130PDS tube I think IMHO is useless, maybe a stronger spider with be a best improving opportunity with better collimation knobs etc..

    Just one more reprocessing that could hurt your eyes....sorry for that.

    Well for the SW130PDS a premium focuser is available at FLO, that´s what I did when talking with Moonlite to design a specific adapter for this scope. But what I don´t see is the carbon fiber as material for it. The carbon fiber offers better strength as the diameter increases (related as well to the Inertia Moment of a cylinder of course). Maybe only a composite made of a sandwich structure with a core thickness of 10mm would be a good candidate in terms of structural performance. PS: for the record I do work as composite manufacturing engineer in an aerospace company.

    A reprocessed file from NGC6819 Foxhead cluster, it was taken beside Barajas Airport (Madrid) Bortle 9 or 10 but pointing outskirts the city and with 30 secs exposures you can deal with LP (also the IDAS helps). 100x30sec subs calibrated with darks and bias.

    A new one believer for the community. What a capable imager is the SW130PDS.

    Another reprocess to M7 with sharpest detail, maybe in north Europe (and UK) you have better weather than in the South these days.

    These cloudy days I am reprocessing some of the 2018 SW130PDS "Greatest Hits", as long as I am increasing the knowledge on the tricks of PixInsight. Here I leave you some of the pics. Cheers. Mario.
  13. Mount, point and shoot....?? Unfortunately It is never as easy.
