The Cocoon Nebula captured with my backyard telescope. 🔭✨

@AstroBackyard You should definitely add Sky Guide to your list, it's by far the best astronomy app I have ever used.

My Must-Have Astronomy Apps 🧐 I have about 15 stargazing apps on my phone (seriously), but I only use about 3 of them daily. It should come as no surprise that the ones I look at most are for checking the forecast (it's a love/hate relationship) 1. Stellarium 2. Astrospheric 3. Clear Outside I've rounded up the 20 best astronomy apps for your mobile phone - from aurora alerts to checking when the next ISS pass is. I bet you'll find a good one you don't have yet: astrobackyard.com/astronomy-apps… Did I miss a good one? Let me know!

@AstroBackyard Well done!

The Horsehead and Flame Nebulas 🔥📸 I tracked this dramatic area in 'Orion's Belt' for nearly 8 hours to capture the light for this photo. This image includes 2 of the absolute best deep-sky objects in the sky: The Horsehead Nebula and the Flame Nebula. See that bright star at the top of the flame? That's Alnitak - one of the 3 belt stars in Orion. Believe it or not, images like this are possible using a compact telescope from the city (my backyard is a Bortle 6!) For a deep-dive on the telescopes I use for photos like this (including this one), check out my updated guide: astrobackyard.com/best-astrophot…

@AJamesMcCarthy Space Debris in front of the sun?

You’ll never believe what I just captured. Not just something I’ve never captured before, but something I don’t think *anyone* has captured before. If you guess it right in the comments I’ll dm you and let you know, if you promise to keep it a secret til I’m ready to share!

@chucksastropho1 Insane! Well done!!

Hello Everyone, Comet LEMMON is going out with a bang The tail was as bright as ever last night. Captured with my Celestron RASA telescope, ZWO ASI533MC color camera, and an Antlia L-Filter.

Comet C/2023 A3 (Tsuchinshan-ATLAS) from my backyard observatory.

@BrandonButch 16,2 GB for my iPad Air 5!!

iOS 26 has been released!

@astrofalls How much would a RASA 11" on a CGX-L cost?

One funny question we get at the observatory a lot is whether or not we are going to randomly increase prices on everyone. It’s funny because this is the total opposite of what will happen. The core mission of starfront is to improve access to dark skies, and so the cost for you will only ever go down. This post is really to announce that we are cutting the cost of our heavy tier size from $799/mo to $399/mo. Sticking to the mission of making dark skies accessible to everyone!

@r3a9an_k_ @DrVooDoo13 If I forget to turn on the shielding gas when TIG welding stainless steel, this orange color appears over the entire workpiece. I think it results from severe oxidation of the stainless steel.

@DrVooDoo13 we don't know what the test tiles were made of

after reading replies, all the orange does appear to come from these 3, so I'm buying the rust theory

@r3a9an_k_ This orange color comes from severe oxidation of (stainless) steel.

@chucksastropho1 Beautiful! Well done!👍

Here is my latest capture - the Lagoon Nebula (M8). It's a giant star-forming nebula that is visible to the naked eye under dark skies. M8 is between 4,000 and 6,000 light years from Earth. Celestron RASA telescope ZWO ASI533MC camera Antlia L-Filter Starfront Observatories, TX

@AstroBackyard Beautiful!

The Veil Nebula 📸 The western portion of the Veil Nebula is my absolute favorite, with that iconic star glaring at the center of the 'witches broom'. I captured this stunning supernova remnant in just 1 night from the backyard using the new Apertura CarbonStar 200. While I am usually a refractor guy, this astrophotography-first reflector is super easy to set up and can handle my 2600 (APS-C) camera sensor. I used a color camera and a dual-bandpass filter to isolate the intense gases of this deep-sky object (mainly hydrogen and oxygen). I hope the Western Veil Nebula is on your 'must-shoot' list this summer. Equipment Used: Telescope: bit.ly/4o010mQ Camera: bit.ly/3CaQWUI Filter: bit.ly/3SxH7Gl Mount: bit.ly/3WNMemz Image Details: 72 x 300s (6 hours total exposure)

@AstroBackyard Incredible!

I've been learning how to capture the sun! This is a nice solar prominence spotted on Tuesday 🌞

@Erdayastronaut Instead of pushing the rocket, the arms could be used to fuel the rocket a little bit longer. A flexible hose for cryogenic propellants is needed.

New video in 20 minutes! What do you think? How much performance increase would a Starship yeet produce, how much energy would be required? 🤔 Get ready for one of the most numbers heavy but fun videos I've ever made!

@Erdayastronaut I think it would be easier to build a higher launch pad and launch it from there.

@BStarr119 💯

CyberBrella is the redneck way to cybertruck ✅

Galaxies M81 and M82 captured with my backyard telescope. 🔭

@GJDonatiello Incredible! Well done!!

M8 - The Lagoon Nebula (below) is a giant H II region in the constellation Sagittarius at 4,000-6,000 light years. M20 - The Trifid Nebula is a combination of an open cluster, emission, reflection and a dark nebula that divide into three lobes. +ALT text flic.kr/p/2rawRRX

@DJSnM Radiation

Any guesses as to what this is?
