RASAでナローバンドフィルターが使えるようになるオクタスライドなる製品が出た。RASA11用のフィルタホルダも開発中とか。RASA8だとオブストラクションがデカすぎる気がするけどw RASA11だったら許容範囲なのでは……

Chris H. scored a 2-for-1 w/ his latest 📷️, featuring #NGC6888 & the elusive #Ju1 just below it. Combining fresh Ha narrowband data from '21 & the bluish-green OIII fringe surrounding the Crescent, adding incredible depth to the image.

So I have two other setups that are stable. I have Redcat/AM5 rig I use with a 2600MCP, and I have a RASA8/GM811 (same camera). I'm looking/piecing together to set up an 8" SCT rig as well for deeper sky shots. All of which I can setup at my observatory and or Kopernik Observatory.

About 12 million light years away, #M81 (#Bode'sGalaxy) & #M82 (the #CigarGalaxy) lie in the constellation #UrsaMajor. This stunning spiral & irregular galaxy duo was captured in about 12 hours of exposure w/ the #Celestron #RASA8 & Light Pollution Reduction filter by Mike Shapiro.

And now for some actual content. This is my 2024 iteration of one of my favorite targets. M42. Pleiades. The Seven Sisters. Just shy of 17hrs with my RASA8 hosted at Starfront Observatory in Texas.

Paul, what semi-permanent mount would you recommend for a RASA8 and Edge HD 9.25? Something beefy and heavy is fine. A few years down the road I’ll be close to getting both rigs. I’ll be putting them on a wheeled tripod base and rolling them out onto a concrete pad to shoot, not on a permeant pier.

✨ The Flower & the Eye—a celestial masterpiece, skillfully captured by Ryan. In the bottom left corner of this image, we encounter SH2-101, the Tulip Nebula, in full bloom. #Celestron #RASA8, all from a Bortle-7 backyard in Kitchener.

Every winter, I look forward to Orion rising, and with it the Orion Nebula. This is one of my deepest images yet. Almost 10 hours of imaged at f/2 from light-polluted Long Beach.

10 seconds with the RASA8 - straight from the ASI183MC camera. This is all I got before the clouds moved in.

When the skies are calling, you pack the car, chase the dark, and let the stars guide your way.⁠

Chris spent the weekend in the #EasternSierra, where the #RASA8 captured the:⁠
🔹 #ClamshellNebula
🔹 #M5
🔹 B142-143⁠

This is what happens when clear skies meet fast optics—and you answer the call.⁠

Getting setup to do some astrophotography with a #RASA8 and an 8" Newtonian in South East Queensland. Had to wait until midnight for the 1/2 moon to set.. hence the shadows. Don't look to close at the cable management..

Realizing that it’s been a month since you posted this… but my rasa8 has been running at Starfront since July. AMA.
