Denizens of the Solar System

Most of my early planetary and Moon images shown here were obtained from 1-2 minute movies taken using a converted Logitech Pro 9000 web cam through a 10" LX200R at prime focus. Starting in May 2015, I used a Celestron Skyris 132c single shot color camera and a Powermate 2.5X. I was very happy with it until it started acting up on me, forcing me to do some research on new planetary imaging cameras. So, since October 2018, I have started using a ZWO ASI385 camera, usually with an IR-cut filter unless otherwise specified. And now more recently, since 2020, I've started using a Meade 12" LX200 Classic. AVI or SER movies were imported and then processed using Registax 5.1, images stacked and the final image post-processed using GIMP. In 2022, I started using the superior AutoStakkert program for alignment and stacking, but still using Registax for wavelet enhancement.

Comment: The Moon just barely grazed Mars near my house in Concord MA...I originally wasn't going to go to the trouble of getting a picture, considering it was mostly cloudy and I had been having issues with my pointing. However, I did, and it was glorious! At the last moment, the clouds cleared and Mars popped into my field of view! Fate, I tell you... I got this beautiful image with a surreal look to it that is ultimately mesmerizing... a fitting metaphorical image for Artemis: first the Moon, then to Mars!

Comment: I have been strangely drawn to this part of the Moon for decades now. I even have a B&W photo I took of this same region (coincidentally) using a film camera on my old Edmund 8 inch f/5 scope about three decades ago! I finally realize why that is...near the center of this photo is the crater Kant, the namesake for my website and a tribute to perhaps THE most enlightened individual on this planet. Interestingly, the location for the Apollo 16 landing site is near the left edge of this photo as well.

Comment: Part 3 of my triple planet image acquisition. Here's Mars using an orange planetary filter. I was a little perplexed why I couldn't see much detail on Mars, given its proximity to opposition, until I learned of the global sandstorm that had started June 20th! It's the first time in a long time I was truly disappointed in an astronomical event - I was so looking forward to getting some good views of Mars this opposition, but looks like this might last until September!! Sheesh. We'll see.

Comment: Since Mars was so bright, I could use my dark blue filter (which I rarely get to use) and still get a very nice frame rate. I was pleasantly surprised with the wonderful detail this filter was able to extract. Usually blue filters are supposed to only enhance polar ice caps and limb haze, and generally obscure surface features. I've read that ocassionally surface features are darkened and made visible as well (as in this image!), but that the phenomenon is not well understood.

Comment: The next time Mars will be this close and so well positioned in the sky, it will be 2052 and I'll be an old man! This image was taken with Mars at an equatorial diameter of just a shade over 20", 2.5" less than at it's closest approach of 38.6 million miles on Oct. 6. What can I say? the weather just wouldn't cooperate. Nevertheless, I have some nice detail, with the south pole on the top, and high altitude clouds on the bottom. I can add this to my collection of previous Mars opposition images. Here's a great schematic showing recent oppositions and the next one 26 months from now.

Comment: I really didn't think the weather would cooperate, so I didn't really prepare for this. But this is the beauty of having a semi-permananent mount with a beautifully aligned scope...everything was ready to go within minutes. The clouds cleared and I ran out to uncover my scope. I hadn't even tried out my ASI2600mc for planetary imaging yet, but the standard ZWO capture program let me get it up and running just in time to catch some spectacular photos of this 1-in-800 year event. This image is what you would have seen had you looked through my 12 inch scope at 4:24PM EST on the day of the solstice. The images here (a stacked version) and here (a magnified, more focused version) are better, but I liked the spontaneity of this one - not completely in focus, but wondrous in the realness of the event - even the great Red Spot made an appearance. Now how spectacular is that? So big deal you might say...a part of me thought the same initially...the event has no significance physically - just a meaningless superposition of two planets we see all the time. But then I thought...think of how beautiful these two planets are...the largest planet in our solar system, with colored bands and a 400 year old raging red storm - the other, a gas giant planet with almost fake looking (but real!) rings of ice and rock - both in the same field of view for human eyes to witness in a moment in time that won't come again for almost a thousand years. You're alive now in just the right time in history with technology sufficiently advanced for you to get to see it. That's something isn't it?

Comment: Here is Mars using a dark blue filter again but this time using my new ZWO ASI385 camera. Mars is only half the size it was during opposition. Odd thing is the color of Mars using this filter was much more "normal" with my Skyris camera...not sure why that would be the case. South is at the top, and east is to the left. Notice the phase of Mars is completely obvious here, with Mars only 87% illuminated.

Comment: Here's my first picture of Mars since I started working with the Skyris. Seeing was horrible, but I still managed to get some detail from the red planet. If you click here, you can compare my image with a labeled picture taken by Phil Miles with his 20 inch scope around the same time as mine. The main structures on Mars came out quite nicely despite my poor conditions. What I thought was an artifact of my processing also turned out to be clouds at the south pole! I often go by Registax's call on quality and sometimes even hand pick planetary images. However, this time, Registax indicated that all but about 100 images were any good, so I decided to use all of them. Shows you the power of image stacking!

Comment: My best image of Saturn yet! I could always get Cassini's division to the left and right of Saturn, but imaging it in front and back was always a challenge...you can just barely make it out in this image! You can also clearly see a major cloud band around Saturn's equator and a fainter one higher up. To get this image, I stacked over 2800 images extracted from a video taken at exactly midnight the morning of June 24, 2016, only three weeks after opposition, using my Skyris camera and powermate. Saturn's low altitude also resulted in significant atmospheric dispersion causing the rings to appear bluer on top and redder on the bottom.

Comment: One of my first small wmvs for a double moon transit is shown here. You can see both moon shadows clearly, with Ganymede casting the upper right shadow and Europa casting the lower left. I remember the first time I ever saw a moon transit across Jupiter's surface. I was only 16 years old and likely only one of a handful of individuals on the planet witnessing the event. Realizing you're watching the shadow of a real object moving across the surface of another planet over 400 million miles away is a humbling experience - making you truly appreciate the physical reality of the Universe.

I was really looking forward to the multi-shadow Io-Europa event the next night, but though the sky looked clear, the atmospheric conditions were horrible and I couldn't get much of a shot. This night was not great, but I still managed to pull off a half-decent image.

Comment: Funny how comets that are often predicted to be spectacular end up being duds, while others, like Neowise appear suddenly and surprise us. This comet was discovered by the Wide-field Infrared Survey Explorer (WISE) space telescope in March 2020 and is the brightest comet seen in the northern hemisphere since Hale-Bop in 1997. I was surprised to be able to see its tail visually quite easily. I took this about an hour after the sun set on July 15, 2020 using my DSLR with a 200mm lens on a tripod and a 10sec exposure using an ISO setting of 1600. Here's another picture of it.
Designation: Comet-46P
Alternate Name: Comet Wirtanen
Constellation: Eridanus
Imaging Date: December 7, 2018
Imaging Location: Madison CT
Exposure Time: 50 frames@20sec ~ 16.7min
Gain Setting: ISO 6400
Imaging Device: Canon Rebel T3i
Optics: LX200R 10" SCT
Focal Reducer: Optec Lepus 0.62X
Filter: none
Comment: Still at only magnitude 6.0, Comet Wirtanen should hopefully be brightening as it gets closer to the Sun. This GIF shows the traversal of the comet against the background star field in Eridanus over a period of about 25 minutes. The field is about 30' x 20'.
Designation: Venus-and-Jupiter
Alternate Name: Venus and Jupiter Conjunction
Constellation: Leo
Imaging Date: June 30, 2015
Imaging Location: Concord M
Exposure Time: 1 frame@3msec ~ 0.003sec
Gain Setting: ISO 400
Imaging Device: Canon Rebel T3i

Comment: I got lucky with this shot! Just as the clouds came rolling in, I managed to take this image of both Venus and Jupiter a mere third of a degree apart on June 30, 2015! Of course, Jupiter had to be enhanced separately, but with a little work, the composite came out great! If you look closely, you can see several bands on the planet, including a small reddish smudge, which of course, is the red spot! - I verified it wasn't an artifact of the processing by looking up the transit time of the Red spot - right where it was supposed to be! Pretty amazing considering the magnification and the resolution of the image! This image also shows that it *is* possible to get a reasonable image of both Venus and Jupiter in the same frame using a single exposure time (in this case 1/400s and ISO400), provided you can enhance Jupiter sufficiently. Regarding the image processing: Jupiter was taken from another frame with the same exposure time but only about 30 seconds after the first Venus/Jupiter image was. The Jupiter region in the second image was enhanced, then cut out and pasted over top of the Jupiter in the first Venus/Jupiter image, then blended around the edges to improve its appearance. Absolutely, creative license, and maybe too much, but representative of the reality at the time, and the end result was a quite pleasing, capturing the moment as I saw it. To me, that's what much of this is all about - preserving memories and capturing the Universe's best moments!

Moon - Montes penninus  by Terry Riopka
Object: Jupiter
Description: First Skyris Image
Imaging Date: May 23, 2015
Imaging Location: Stow M
No. of Stacked Frames: 4776
Imaging Device: Skyris 132c
Optics: LX200R 10" SCT
Optical Train: Powermate2.5X
Comment: My first serious Jupiter attempt using my new Skyris camera! With my Powermate 2.5X, I can get 0.12 arcseconds per pixel resolution, which, combined with the higher frame rate of this camera, has the potential for some pretty nice images. Now, obviously, no one can expect to get much better than about 2 arc seconds visual resolution, but with "lucky" imaging and image averaging, a finer resolution can give you more pixels to interpolate regions in the image to ultimately obtain better images. If the image above under fair conditions is any indication, I should be able to eventually get some pretty impressive shots (for Concord that is:)
Object: Moon
Description: Montes Apenninus
Imaging Date: November 3, 2022
Imaging Location: Concord M
No. of Stacked Frames: 3774
Imaging Device: ZWO ASI385
Optics: LX200R 10" SCT
Optical Train: Powermate2.5X
Comment: Well, my Meade 10 inch LX200R still has it! I managed to RE-fork my 10 inch to near perfect pointing accuracy! I couldn't believe my luck - pointing to within a half radius in my 26mm eyepiece, just like when I bought it! Needless to say, I was very happy, and after collimating, spent the rest of the evening observing Jupiter and the gibbous moon. While at it, I thought I'd hook up my ASI385mc to the scope and got this wonderful view of Montes Apenninus and the Apollo 15 landing site. You can even see Hadley Rille in the upper right corner, where the Apollo crew landed, shown magnified in the inset image along with the landing site location. This was the fourth landing, with the first use of the lunar rover. The astronauts also did the famous Galileo experiment and returned the "Genesis rock", one of the oldest rocks ever returned from the moon and estimated to be over 4 billion years old.
