New mount in house (Uwe Deutermann)

New mount in house

Should be able to get better guiding now. Losmandy GM811G arrived today. Weather is not allowing me to test it out yet, but I have to go to work tomorrow morning anyway, hence good that it is cloudy, otherwise I would have spent a vacation day :-).

Update for the new Losmandy GM811G mount:

Plus points:

- Transportation! Since I have to carry the mount in and out I wanted to have a mount that is easy to move around, but still can handle a heavier load. This mount could not better, with the RAEXK addition the declination axis can be separated in the easiest way, super quick. For older folks like me fantastic.

- Guiding: looks very good for me, maybe because I had not such a good mount before. Polar alignment and alignment stars need to be done thoroughly though!

- Instructions: the instructions on the web about the Gemini system are awesome!

- Very sturdy, everything locks up very well.

- Azimuth and Height knobs to polar align are very nice and easy to handle (waiting for polar scope though, on back order).

Minus points:

- Cannot get used to the mini hand controller, I try to avoid it as best as possible, do almost everything via Ethernet connection.

- No place for the power supply, or eye pieces if you want to look through the telescope for a bit.

- Very first star fix after polar alignment is by some degrees off, I must do something wrong (not GPS coordinates or time, I made sure that those values are on the money). Second and all following objects are within 1 degree, that is good.

- The web interface to select objects and then move to them could be better (more compact), I have to scroll in order to select "move to selected object".

Description: Ready for more action with the new mount with my "old" 6", 1200mm refractor. After polar aligning with Sharp Cap and 3 alignment stars the average precision in PHD2 was around 0.6" with 4 second exposures. I was pretty happy about this! I cannot setup a good model for the mount since my field of view is limited, and for that I will not whine about this good guiding. PHD2 screen shot will follow.

Description: "typical" PHD2 graph with the new mount. I doubt that I can get it better than that, maybe someone else has some suggestions. Would that accuracy be good enough for, let's say, 2500mm focal length?

Description: Guiding graph of the MyT (recommend!!) with the super long 6" refractor (1200mm FL) after really paying attention to the T-Point model and polar aligning the mount very well. Cannot be unhappy with this on a portable tripod!

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
