Another beautiful sunset from Holualoa tonight. ๐Ÿ˜Ž

Thatโ€™s pretty stunning image of M27 for only 50 mins. Nice work! ๐Ÿ‘

Thank you. I used a pretty neat masking technique to preserve details I would have otherwise lost in normal Siril processing. Credit goes to Photon Rookie for sharing a tutorial on YouTube.

Iโ€™m so sorry I didnโ€™t see your note sooner. I have both now and theyโ€™re great. Hard to pick a favorite, but I suppose Iโ€™d recommend the S30 Pro first. Iโ€™m hoping to see an S50 Pro or perhaps an S70 Pro in the next year. That said, if you got the S50, youโ€™ll love it.

Sorry for the late reply. Are you using a smart telescope like the Seestar? If so, you can get some great results simply using the stacking & enhancing tools in the Seestar app. For post processing, take a look at the video tutorials posted by Photon Rookie on YouTube. His are excellent.

Just checked your website. Iโ€™ll be sure to visit next time Iโ€™m in Honolulu.

I agree. Very lucky to be living here. Waikiki ainโ€™t bad either. ๐Ÿค™

Sorry about the late reply. It was just over 2 hrs. EQ mode with 60 sec subs.

Timelapse vid of the Lunar Eclipse. I accidentally stopped it too early, but itโ€™s still pretty cool seeing the start of the eclipse thru totality with color changing. #moon #lunar #eclipse #lunareclipse #nature #astrophotography #nightsky

A still image of the total lunar eclipse early on March 3rd from Hawaii. The image is a full moon with an orange cast to it from the sun light refracted thru the earthโ€™s atmosphere.

The Blood Moon during the eclipse earlier this week. It was pretty cloudy, so I didnโ€™t get the clarity I was hoping for, but I thought Iโ€™d share it anyway. #moon #bloodmoon #lunar #eclipse #astrophotography #nature

M42, the great Orion Nebula.  This is a 2 hour exposure using a Seestar S30.  I learned a masking technique for post processing that really helps to preserve nebula detailsโ€ฆespecially in the center where the long exposure tends to washout the details of the gas cloud.  Thanks to the Photon Rookie on YouTube for sharing the technique.  His skills are undeniably brilliant and he graciously shares them.

My first image using a new Seestar S30 Pro. Conditions were not ideal, but I think M42 came out nicely. I did some post processing in Siril and used a โ€œmaskingโ€ technique that I recently learned from Photon Rookie. #Seestar #Orion #nebula #stars #photography #astrophotography #nature #nightsky

I had an almost identical experience. lol. I bought a Meade 8โ€ Schmidt Cassegrain and took some blurry photos of Orion. Iโ€™ve been enjoying my S50 for over a year and just received the new S30 Pro. Enjoy and clear skies!

NGC-2359, Thorโ€™s Helmet Nebula, from Holualoa HI.  Iโ€™m pretty pleased with it after only 70 mins before the battery died on my Seestar S50.  If I have clear skies again tonight, Iโ€™ll try to add to the stack.  I will also see if I can improve on it with post processing using Siril and Graxpert, etc.

Thorโ€™s Helmet. A beautiful emission nebula in the Canis Major constellation. My Seestarโ€™s battery died and, so I had to limit the exposure to 70 mins. Iโ€™ll try to add more to the stack tonight or tomorrow. #nebula #stars #astrophotography #Seestar #nightsky #Thor #cosmos #nature #Hawaii

Horsehead nebula with part of the Flame Nebula too. Approx. 500 FITs images from a SeeStar S50 stacked and processed in Siril, Graxpert and GIMP.  I like the results a bit more than whatโ€™s possible with the native SeeStar app tools. Sadly, I couldnโ€™t use Astrosharp, since it is apparently only available for Windows; but Iโ€™m looking for alternatives. A big shout-out to Photon Rookie for his excellent tutorial on processing the Horse Head Nebula (among other deep sky targets)โ€ฆheโ€™s truly the GOAT of SeeStar Astro imaging.  Check his work out on YouTube.

Old Seestar S50 image data of the Horse Head Nebula, but I reprocessed it using Siril, Graxpert & Gimp. Thx, Photon Rookie, for the great tutorial. I still need a Mac alt for Astrosharp, if anyone knows of one. #Nebula #stars #astrophotography #photography #nature #cosmos #nightsky

The Hawaiian Hawk. I donโ€™t see these in my yard often, but I got lucky yesterday. This beautiful hawk is only found on the Big Island of Hawaii.

A studio portrait of astronomer Carl Sagan standing with his arms crossed, smiling warmly at the camera. He is wearing a red turtleneck sweater. Behind him is a stylized cosmic backdrop featuring a spiral galaxy and scattered stars, giving the impression that he is positioned in front of a vast, luminous universe.
