Widefield Tulip Nebula + Black Hole + Kidney SHO Hubble Palette (SH2-101, Cygnus X1) RASA8

I have a special fondness for Tulip Nebula as the town I grew up in held a Dutch Tulip Festival each year. Conditions where challenging during the data I captured this data with average wind around 12-15 mph each night and smoke across the Midwest. FWHM for each channel was between 4-4.5”. I also had to scrap 40% of the Ha data due to wind and focus issues.

Last year, I completed a zoomed in version with my Edge 9.25 and this year I wanted to see what a wider field image with the RASA8 could yield. I also wanted to capture the bow shock of Cygnus X1. In addition, I was unaware of the kidney like dust formation in the widefield image on the upper right which I find fascinating.

Sh2-101 referred as tulip nebula is a hydrogen emission nebula located 6,000 light years from earth in the constellation of Cygnus. The nebula measures 28 x 16 light years.Cygnus X-1 is an x-ray source that was eventually discovered to be the first black hole scientist found. It was a large supper giant star 40 masses of the son that collapse directly into a black hole that measures approximately 45 km in diameter. The black whole is in a binary star system with the bright star in the picture (see arrow). The stars are roughing 15-20 million miles part and orbit each other every 5.8 days. The black hole pulls stellar material from its binary partner that accumulates in its accretion disc. As the material increases in energy some of it escapes in jets perpendicular to the accretion disc. These jets are the x-rays that we first observed and created the blue bow shock pattern seen in the image.

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.
