Elephant Trunk - First Light with ASI1600

I recently installed a Takahashi FSQ106 and ZWO ASI1600 on top of the Planewave. I was concerned that this added weight at both ends (counter weight too) would degrade the guiding performance of the Planewave. It does seem to have more variation in the model error, but my guide error is close to where it was before. The model error moved up from 5a-s to 12a-s, and my guide error is usually in the 0.5" rather than 0.4" range.

But this does not impact the results from my 1.46" image scale on the Tak! The resolution I'm seeing from this little scope is quite nice! I haven't got things completely dialed in but I have been able to capture good data.

This is a SHO image with the following blend:

Red = SII+33%Ha

Green = SII25%+Ha 50%+OIII25%

Blue = OIII

Luminance = Ha

Star color is SHO

Pre-processing in CCDStack and Post-processed in Photoshop.

Post-processing included lane darkening with a High Pass filter, Sharpening with Unsharp Mask, Luminance noise reduction via Topaz, color noise reduction with Gaussian Blur and Dust and Scratches.

Description: This is a quick starless version. I used StarNet++ to create a starless version, and then did a difference layer over the original. That allow me to better select the stars and let the PS fill command to the star replacement. I was also able to deselect some non-star areas. Since I don't have any plans for this I didn't do a full job clean up. Just for fun!

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.
