Bad frame

Michael

Hello Lukas,
all the frame of my request SCO2, i got this morning.
One frame is bad (Ha, some meridian flip while exposure).
I have edited the original request to get 8 additional frames.
Can you calculate it for 7 frames?

Next question is, you wrote in april to swap the samyang optic to a sigma.
Can you say, when you will do so?

And the last question is, what's about the issue in RA-axis of the Hakops H8 2.8.
Is there still the issue? Is it recommend to use it?

Thank you
Michael

Hi Michael,

the H8 is out of order, and will remain so for the foreseeable future, regrettably.

The Samyang has been swapped today 🙂

Hi Lukas,

good to see the Sigma.
Although the first frames with it seems to be a little out of fokus,
the BlurXTerminator did a very good job (compared with Samyang-frames).
At which aperture works the Sigma?
When do you take the calibration frames?

Hi @Michael ,

it is regrettably not yet where I want it to be. Main issue is, the change of aperture is purely electronic, so we need to put it on a Canon reflex, change the aperture, and then move it back to the system. Right now it's 1.8 (!)

Hi Lukas

what is wrong with the Sigma?
Is it necessary to change the aperture at work?
I thought, that a aperture of 2.8 would be good.
What do you think, when the Sigma is ready to work?

Hi @Michael ,

we have an issue with the computer, which is very tricky to sort out. Basically when powering on the mount it reboots :/
