Description: Rear panel on the control box. This is a laser cut part and I spray painted it. SendCutSend did the laser cutting and I highly recommend them. They are fast, relatively cheap, and they do great work.

Description: This is a portable Gator rack for audio equipment. It comes with wheels and a retractable handle making it VERY easy to move around. With everything connectorized, it can be rolled out and connected within a minute or two.

Description: This is the automated anti-dew controller that I designed and use on all of my scopes. It simply measures the actual dew-point spread and controls the power to a dew heater controller. I happen to use an Astro-Zap controller on this scope but I used a nicer Dew Buster on my C14. A similar arrangement controls the T-point controller on my 20" system.

Description: Here's a view of the guts of the Dew-Point controller. It is dirt simple. An Arduino controller simply runs a relay to control power to the dew controller. In this case, dual relays wired in parallel provide redundancy. Two temp/humidity sensors provide redundancy and allow signal averaging for better accuracy. The control code allows setting the dew-point spread and latched control of the power prevents rapid switching when the DP spread is at or near the switching threshold. The controller is completely autonomous and starts running when power is applied. I basically never touch it and it works incredibly well to prevent dew and frost on the optics.

Description: The left plot shows the FWHM contours for the first image with the QHY600M. The right plot shows the distribution after straightening out the camera. There is still work to be done on this!

Description: I had a few nights of spectacular seeing. It doesn't happen all the time, but sometimes the seeing in central Oregon can be really good!

Description: V-curve focusing works quite well with the PDMS from Starlight Instruments. Selecting a small central region for focus mitigates the effects of sensor tilt while you are getting it dialed in. There are some excellent tools available for looking specifically at sensor tilt. One is in Nina and the other is in SkyWave from Innovation Foresight. Simply looking at FWHM uniformity throughout the field is a good diagnostic to see the magnitude of the problem but it's a difficult tool for dialing out tilt since it can't distinguish which side of focus is causing defocused stars.

The image will be permanently deleted and cannot be recovered. All its revisions will be deleted too. Are you sure?
You will delete all other revisions (if any), and the originally uploaded image, leaving the current revision as the final and only version of this image.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.
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. |
This image cannot be submitted for the IOTD/TP consideration.
