A quick outing before the weather got bad as a tropical storm hits from the Gulf. I wanted to test the new T-adapter fittings I got for the AT60ED to attach the camera instead of using the 1.25″ eyepiece adapter, like I had to do for the first light images.
A beautiful evening for the Moon and Mars conjunction on October 2, 2020. Condition were so good that I was able to capture the moon rising behind a tree. Usually the muck is so thick at that altitude that I would not be able to get a good image, but this night it was extremely transparent.
The moonrise shot was a single frame. I had to do a composite for the still image of the Moon and Mars together. 10 frames were stacked in AutoStakkert of just the moon and 2 Mars frames were combined for the disk of Mars.
The MP4 video file is the first time I have tried including one in a astrophoto post. It is small enough in size to download in a reasonable amount of time. Video editing software I used was rudimentary and I really couldn’t get the background color corrected very well. I’ll have to find something that can do that job for future projects like this.
The night of August 7th/8th, 2020 was relatively clear, but hot and slightly muggy. Average transparency at first and below average towards the end of the night. I wanted to get out to my dark sky site, but at the last minute decided to stay in the big city, being that the conditions were not ideal.
I observed quite a few things and did quickies on them and some of the images are not really worth being posted. Here is one below of the Ring Nebula, which was. I was actually after the little galaxy next to the ring, IC 1296, which my Canon cameras never showed despite shooting the ring with them from much darker locations. It is nearly 15th magnitude and even dimmer in blue light, where it predominantly radiates
Below is a rendition from previous sessions data and this nights efforts.
Finally, with the Witch’s Broom Nebula data from this night and 2 other nights, I combined the data to make this updated rendition of the W. Veil/Witch’s Broom Nebula. Check it out:
These are all the objects I managed to image on the night of Wednesday, April 29, 2020 and on into Thursday morning. SharpCap 3.2 LiveStacking with dark and flat calibration plus dithering was used for acquisition. Only minimal processing for all of these captures in Fitsworks and PS CS3.
I was trying not to waste a very clear evening after a storm had moved through earlier that day. Not too bad, I guess.
Six images bagged in one night, although a few need at least another nights worth of additional time. Big city light pollution was circumvented with an Optolong L-eNhance filter.
30 second sub-images for the DSO’s. The moon was 5 frames stacked in SharpCap 3.2. The Cone Nebula has 130 subs from last night and 63 from a previous session. I also shot M51, but it was only a few frames before twilight and was not really enough for a display image.
Sunday evening was beautiful here in Cajun Country and I did not let the night go to waste. I shot a number of things, but I went back to the Cave Nebula early on to add more data to my existing image of it.
I shot the moon next, even though the seeing was not that great. I shot 10 stills starting out slightly underexposed and progressing to over-exposed to show the dark part that was lit by Earthshine. My experiment to blend them all together was not what I had in mind in terms of look and feel. Plus, I had shot them in 8-bit mode instead of 16-bit mode in SharpCap 3.2. It was a learning experience, I guess. I’ll figure it out one day, hopefully.
I did the Monkey Head Nebula last and it hardly needed any post-processing. 50 minutes worth of data was enough to show most of it. Guiding and composition were good and the image was easy to post process. I packed it in after this, since it was nearly 2:00 am and I needed at least a few hours of sleep before work Monday morning. lol
Like before, these images were all taken from a metro area with Bortle 8 red zone light pollution levels. An Optolong L-eNhance filter was used to shoot through the muck.
