Spectre Variant 2 (CVE-2017-5715 branch target injection)Īs you can see, script try to check if in my machine are some mitigations Spectre Variant 1 (CVE-2017-5753 bounds check bypass) Then i have executed the script (Is recommended to execute script being root)Īfter password insertion, the script can run: below results: I have just tried on my not so new pc this interesting script: Specter-Meltdown-Checker, as specified also in instructions, it is not a bible, but surely it is something could give you very useful informations – this script give you the possibility to check your pc vulnerability to Spectre (2 variants) and Meltdown.įull Hardware details are here , (i have used lshw command) You can see my astro-pictures in photogallery This telescope (Schmidt-Cassegrain type) is excellent for planetary viewing (and also photography, why not).įurthermore, if I feel like taking professional deep sky photos, I can “transform” stock azimutal mount into equatorial by buying a special wedge and buying a focal reducer. Regardless of this, I would have had space problems anyway (keeping it mounted was not an option, since it would take up much more space than the Dobson): in addition, I’ve imagined myself in the garden, able to mount everything, balance the weights etc, and I told myself (and my laziness) that knowing myself I don’t know if I would always have wanted to.Īt that point the choice paradoxically became simpler, towards a short tube: between a Makutsov (127mm, more would have been a drain) or … a 150 SC, which is precisely the Celestron tube I bought. So either I took a smaller diameter tube (150 mm) or I would have had to invest in a more performing mount (and much much more expensive, also considering that as i said, i wanted a goto motorized one). although obviously in the shops they sell them (i mean mount+scope) coupled. I then shifted my interest to equatorial mounts, which are ideal for astrophotography: I was thinking of a 200 Newtonian (Skywatcher) with a NEQ5 mount, but I was told by many experts that the mount would be undersized with that tube, very long and not at all light. I initially started with the idea of a Dobson 200 mm (collapsible with Go-to), but then I realized that I would need space in the house and above all moving it would not have been easy due to the considerable weight Premise, I absolutely wanted an automated telescope, that is, a scope that can point and above all track the object: this has inevitably increased the budget.
