Re: RMO chasers Perseids 2022 ...

Hi Stu, That is a nice record and very clear uptick from the Perseids. I am starting to doubt about my system after seeing the results but no idea of what could have gone wrong. Today I caught more then the day before yesterday and yesterday. Look at the today's graph. RMO_Ehlert_Nelson_Zapata_20220...

The Mexicans had...

Re: Less diameter / diaphragm for more contrast? (Quark + APO)

Hi,

Stopping down will not bring you more contrast. Contrast in this case has something to do with the adjustment of the etalon eg. to be in band or not ...

IMHO

Stopping down will define if you under- or oversample as far as I have learned here.

Hi Magnus, Great image. I could not get the orientation exactly as in GONG today. Look at some full disc images in this forum and you will see that you need to rotate 180° and done.

WoW Rainer. That little detached prom off the NE limb looks really faint in your image. I am surprised I picked it up so easily in my SMII60 visually. First in DS and easier in SS. I picked it up casually. It was out of view in my GONG reference image. 🤔 Thanks for your verification 👍🏻 James Hi, Yo...
