Boris The Spider

A. I recently bought some new gear - an ASI1600mm and a ZWO 2 inch filter wheel. The filters are over-sized, but I can upgrade my camera in the future without having to buy new filters. On the first night, everything was going well until the filter wheel change to the blue filter. Every shot from then on had a weird artifact in the upper corner, even on different filters....

Description: So I took the camera off the filter wheel in the morning to find a scratch!! Maybe a loose screw in the filter wheel was dragged across the camera? Wait, that blob looks like bug guts. :( The camera cleaned up nicely....

Description: I'm going to need some pretty good flats to eliminate this! I cleaned up the filters, and found Boris dead in the filter wheel. He must have climbed in when I loaded the brand new filters into the brand new filter wheel. Problem solved, right? ...

Description: On my next night, my luminance shots looked like this. Its the ghost of Boris!. How can this be? I took everything apart the next morning and there was nothing in the filter wheel. There must be a way in and out for spiders.... (or it was a real spider ghost)

Description: There are 8 holes for camera mounting on this wheel. The ASI1600 covers only the inner 4, leaving the outer 4 open. This must be the path the spiders are taking, so cover them up if you live in a part of the world like me, where you are never more than a meter from a spider at all times!

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.
