Getting close to calling it for the season on my Rosette Mosaic project. To be continued next season. As it's Galaxy season was considering options for a project. Might do a 9 panel LRGB mosaic of Markarian's Chain. - #astrophotography #astronomy #galaxyseason

Watched the movie Elevation. Been wanting to see as it was filmed here in Colorado. Enjoyed it. Interesting concept. Then at the end this happened. They were looking through a telescope. I mean, no one caught the fact the telescope was backwards. - #moviemistake #elevationmovie #colorado #astronomy

Finally! Telescope is back up and running. Back to my Rosette mosaic project. Getting late in the season, may only get a few more runs then shelve until next season. It will be time to pull out the ol’ Meade LX200 10” OTA. Tune it up and enjoy galaxy season. - #astrophotography #astronomy #colorado

WOW! 21 days since my last post. Life's been busy & the weather here in Colorado has been crap. I did get a new dovetail plate for my telescope. Feeling better about it's placement in the saddle. Weather may improve the next few days, hoping I can back at it. - #astrophotography #astronomy #colorado

How the mosaic looks like after aligning the 4 panels. 11 hrs of data per panel; 44 hrs total Ha. Now time to do SII, or maybe OIII. Planning on same amount of exposure time for all filters, 132 hrs total. If the weather Gods cooperate I might get it done this season. - #astrophotography #astronomy

Grabbed a shot of my setup before covering it this morning. As with most, I’ve been fussing with finding the right cable mgmt solution. Recently got some Alex Tech split sleeving. It’s worked well so far. Doesn’t get as rigid in the cold as other solutions I’ve tried. - #astrophotography #astronomy

Cold has loosened its grip and skies cleared. Got the telescope back up, realigned, back at the Rosette Mosaic project. Had an Amazon delivery tonight. Driver saw my setup, rang the doorbell and we had a great chat. Turns out he’s into #astrophotography as well. Talked about projects. - #astronomy

Processed latest data for my Rosette Nebula Mosaic Project. Last image I shared was 2 hours per panel; 4 panels entire image. Since I've gotten another 4 hours per panel. Here's a comparison image. Right is 6 hours, left from the 2 hours. Details starting to come out. - #astrophotography #astronomy

Did a screen capture last night of N.I.N.A. doing the meridian flip process. Another successful fully automated run. With the extreme cold coming in I have to take down the telescope and bring it inside. Doesn't look like any imaging sessions for quite some time. - #astrophotography #astronomy

Super stoked! After a lot of tweaking I finally have a fully automated run to include my first successful meridian flip! My sequence has completely done everything. When tonight’s session is done, I’ll have 14 more, 30 min each, Ha images for my Rosette mosaic project. - #astrophotography #astronomy

After our big move finally getting first light at our new place. I set up the scope a couple of days ago but it’s been non-stop clouds since. Patience paid off. Back to my Rosette project. It will also be the first time to do a meridian flip. We’ll see how it goes. - #astrophotography #astronomy

Happy New Year! May your skies be clear and your telescope guide true! Unfortunately nothing but clouds for me the next few days. Itching to get the telescope setup and first light at our new home. - #newyear #2025 #astronomy #astrophotgraphy #telescope

We’ve been settling in at our new home. No telescope time yet and probably not until after Christmas. Meanwhile thought I’d share a 3D Blender project I did a while back. Inspired by an image I came across online. - #blender #3D #SciFi #3Dart

Update on my Rosette Mosaic project. So far 4 exposures per panel, 4 panels, Ha only at 30 mins each; 2 hours per panel and 8 hours total. With weather and my family moving to a new home in a couple of days, no work will be done for a bit. Hoping to pick back up soon. - #astronomy #astrophotography

More OAG action and I'm in love. Started a new project on the Rosette Nebula. Doing a Mosaic of 4 panels. Very beginning results of two nights, HA only, 30 min exposures, 2 images per panel. No processing other than putting the panels together and doing a GHS stretch. - #astronomy #astrophotography

Should be a good night to see those planets. Also a great chance to checkout and learn about the historic 20” Clark-Saegmuller refractor.

Follow up to my new OAG. The quality of the guide is definitely changed. Been testing exposures at times that before were not possible with my guide scope. I've done 20 mins consistently. Decided to try 30 mins on the Rosette. No processing done, just a stretch. - #astronomy #astrophotography

Did my first ExoPlanet observation and excited to see results showing I caught the transit! - WASP-12 b is a hot Jupiter that orbits so close its star that it’s being torn apart. - #astronomy #exoplanet

So excited! My OAG and new guide camera arrived! Upgraded to the ASI174mm Mimi from my ASI120mm Mimi. Needed the larger sensor to match the mirror in the OAG and have enough stars for guiding. Now to get it installed and then everything focused, hopefully tonight. - #astronomy #astrophotography

Mars is now very close to the Beehive Cluster (M44). A stunning Binoculars and photographic opportunity. Look east from around 9.30pm. 🔭 🧪 #astrophotography

Excited to be converting over to an off-axis guider for my telescopes. Been wanting to use my Meade 10” 2500mm LX200 OTA more but needed a better way to guide. After some research I decided to go with the Askar M54 OAG. Can’t wait for it to get here! - #astronomy #astrophotograpy

Today ‘s 5787 known exoplanets from NASA’s Exoplanet Archive overlaid on the Gaia EDR3 star map of the Milky Way. Transiting planets account for nearly 3/4 of confirmed detections. If we just built 360 more Keplers, we could finish this thing. 🔭🪐

Finished up my work on NGC 2174, the Monkey Head Nebula. 5 hours of integration per each Ha, SII, and OIII filter. Done up in the Hubble palette. Rather pleased with the result. - #astronomy #astrophotography #thenightsky

The bright moon is too close to my primary subject, NGC 2174 (The Monkey Head Nebula). So having some fun with Barnard 33, the Horsehead Nebula. Trying some 20 minute exposures in H-Alpha and so far the telescope is tracking well. - #astronomy #astrophotography #thenightsky

One of the fun things I like to do with my 3D work is recreate scenes from movies/shows. From one of my favorite classic sci-fi movies, Forbidden Planet. I wanted to recreate the landing of C-57D on Altair IV. It was a fun little project to work on. - #Blender #3D #3dart #art #scifi

Recent astrophotography image. After several nights of imaging using H-Alpha, Sulfur II and Oxygen III narrowband filters with a total exposure time of 5 hours per filter. This is my take on the Tadpole Nebula (IC 410). - #astronomy #astrophotography #lookup #thenightsky

10 years ago today I saw the movie Interstellar. It has been one of those movies that has stuck with me. This is my 3D version of a scene from the movie where they approach a planet caught on the edge of the black hole Gargantua.

Time for something new. One of the many that have moved on from X to something more sensible. I was a long time Twitter user but it died some time ago.
