I have a Primalucelab Sesto Senso focuser that I used for Deepsky photography, but I don't know how to connect it to the Pst focus screw,
I searched online for some ideas or projects but couldn't find anything

alessbonsai

How do you keep the sun so still? in my house with the terrace that vibrates, and the mount always out of polarity I always have vibrations

alessbonsai

alessbonsai

I give up on the idea, I don't have an electronic focuser and I would always have problems staying under the sun to make a focus

alessbonsai

I already have two Raspberries and the advantage would be that of not being directly connected with the laptop to the telescope so I wouldn't be forced to stay under the sun, yes fircapture exists, but it doesn't have all the cameras available

alessbonsai

Nobody uses Raspberry for video capture?

alessbonsai

well, I saw that the bresser is cheap, do you have any other ideas besides these two models?

no unfortunately by always using different crops I can't do flats, then the sky changes often and I have little time available

Can you recommend a 102mm refractor to wear for the sun? I saw the BRESSER Messier AR-102/1000 Hexafoc Optical Tube, 339 Euros and an AP 102/1100 ED Planet OTA Apo Apochromatic Refractor, 800 Euros, if you have any other advice?

Rainer, all. The best way to gauge the color of the Sun is probably visually. The problem here lies the extreme contrast between the photosphere, the sunspots and the black background outside the disk . It's a large dynamic range for the eye to adjust for. Another issue is one needs a filter that d...

Experiments and reflections on RGB photography of the sun continue. point one the earth's atmosphere is an excellent filter and blocks almost 50% of the red color emitted by the Sun and therefore a balanced photo of the sun looks very pale blue if not bluish. point two, even if there were no earth's...

The sun is a black body, but the emissions recorded by the sensor are not linear, the sensor is very easily blinded by higher frequencies which are more energetic.

Hi. The diameter of the etalon is 20mm and it's used at F10 in the PST. The collimating lens is a -200mm focal length. The collimating lens has to be 200mm in front of the telescopes focus point in order to produce a 20mm diameter collimated beam through the etalon. The re-focus lens is +200mm foca...
