Alexandra

The equator is running from the left upper side to the right lower side in an angle of 27°

Hi,

I just found the image below. At least on Monday the Palm tree branches and leaves were useful

It is the shadow on the stairs to my observatory.

Hi Tareq,

Just a 1:1 crop, a simple Histogram stretch and a tiny bit of Unsharp Mask. Nothing else as I still do not understand Over- or Under sampling

Important for you is to focus near perfection.

Great images and Timelapse, Rainer. I’m surprised you didn’t make it to the centre line though. You can’t have been very far away from totality. Stu.

Hi Warren, Excellent. The best quote of the day was from a 5 year old girl that I showed the sun on my phone from the Seestar and she looked at the phone, then looked at the Seestar, and then looked at me and said, "That little thing does all of this?? That's cool!!" :girl: That little Gir...

Hi, Good, Eclipse hassle is over and we can back to normal life until maybe a week before 30/03/2052 :mrgreen: Now it takes some time to get back into the saddle with the equipment and directories and image settings but here we go slowly. Today's disks taken a bit late because I was changing some th...

rsfoto · Re: April 8 2024. First eclipse pictures! Hi James, Well done.

Hi James,

Well done.

rsfoto

Well done. How about the sag in that long optical train especially the push in connection at the very first point in the focuser.

You are a great machinist. Why not make a threaded adapter for that point?

Excellent timing. Is the pilot your friend?

Well deserved SPoD

Hi, Forgot to add yesterday. The temperature dropped by 2.8°C as you can see. uddenly my visitors and I feelt cold and everybody said :cool: At max. coverage 12:17 the temperature was 25.2°C from the highest point 27.9°C at 11:32 local time The time on the graph is not correct. It is one hour ahead....

Hi Warren,

Excellent and for sure you had fun. Even I had fun and just being a partial eclipse at my location.

The first video is very impressive, I am presuming you kept it at a fixed exposure and it gradually got darker and darker, wow!! very moody! Great videos of the eclipses too, you were so close to totality! Alexandra Hi Alexandra, Thanks and Right. Did not touch the exposure time which is 0.196ms us...

No, I did not stream but just posted my videos

Hi,

This is what I harvested today. All went trouble free except was a bit hazy due to SMOG. 3 hours and 5 minutes compressed in both videos to about 2 minutes 30 seconds. Thanks for watching

T -36 and so far looks good except a lot of SMOG... but better then clouds

Hi Brian,

Excellent. No green flash?

I was a bit worried about your location but today the weather looks good over there for today. Maybe a bit of Cirrus ¿?

Good luck

So that's a doublestack, quark and lunt - is it easy to focus?

yes, is focussing a known issue with this combination?

From what I see you are in Band and about focusing, focusing has nothing to do with being in band or not ... IMHO

Hi Alexandra,

I have a friend who is going to Melchor Muzquiz in the state of Coahuila, North Mexico, where the totality is 4m29s and the weather forecast looks exactly as you said. They rented a house there.

32 degrees! :shock: At least it doesn't say wall to wall sunshine for Sunday and Tuesday and cloudy on Monday, if it were in the UK the forecast would be like that. Hopefully you should have a reasonably good chance. Alexandra Well, I still remember October 14 2023... I would say, let us stop talki...

Well done James

What additional filter do you have in the white light image as you name it 393.3nm?

I have two choices. I can drive up to my hometown 3 hours away and stay with my sister in Ashland, OH where they get over 3 minutes of totality or stay down here and drive 45 minutes and get over 3 minutes of totality and the forecast keeps flipping back and forth as to which one is better. At this...

Nice disk. As Mark mentioned, move the disk around in the FOV to find the best overall tuning. It appears in this shot that the sweet spot is to bring the disk down a bit lower in this FOV. The typical recommendation is to first tune your main etalon, then add the DS unit and tune that one. You can...

Hi,

US $ 200,00 is a good price. I would recommend you anodize all parts for better durability over the years. Anodize in natural color. Black is a bad idea due to heat.

Well done.
