Ekos focus module does not provide "v-curve" #62221
Hi,

I am new to Astroberry and trying to get some initial experience. Currently, I am stuck with the focus module to get an optimal focus point of my camera. Regardless of the various settings (initial steps etc.), once a star is selected and the framing process is started and the star is shown in a subframe, the HFR value does oscillate around the initial HFR value rather than decrease and show the v-curve.

Does anybody made such experience or can explain what I am doing wrong? Any hint is welcome.

I see Astroberry a very powerful tool and would love to use it in the future.

Thanks,
Kurt

Are you attempting to auto focus drive a camera lense on the camera body?

Yes. I attempting to auto focus the Tamron lens mounted on my Canon EOS 550 Da. At day light I tried to move the focus point using the focus-in and focus-out buttons and this did work, I saw the focus point moving. When I did the same at night I did not see any effect. Very strange.

You will need to begin close to focus with enough exposure to pickup stars to focus on. What did the focus frame show?

Well, I was able to select a star in the full frame and start the framing. The selected star was shown in the subframe along with its HFR value. I tried with various initial HFR values. Regardless if HFR initially was at 1.5, or 3.5 or 7.5, the subsequent HFRs did oscillate around the initial value.
OK, I will try again at next opportunity (eventually in the course of next week) and will report.

Thanks,
Kurt
