Wolf-Rayet 134 was a challenging target. I had to push the Oxygen to see enough detail in the bubble. This was also my first time using the Antlia Quad filter to capture more natural looking stars than the Ha/OIII filter produces. Others had done a much better job on WR 134, so the point of this video is simply to show what you could expect to get from a basic telescope like the Celestron 6SE imaging in Bortle 8 light-polluted skies. CS!
And here I was thinking I should have gone for the tri. I don't know if I like how much the quad bleeds into the IR. I'm working on a project combining the quad, with the dual and UV/IR Cut, and the Quad's stars actually seem washed out in comparison to the UV/IR Cut, even though it picks up more nebulosity. CS!

Nice video, and an amazing picture! Question, what is the device you put on the tube of the 6SE?
Thanks! I added a counterweight to the OTA because I had to push it forward past the primary mirror in order to fit the camera. Here's a closer view (before I added the filter tray) Celestron NexStar 6SE With Wedge Astrophotography Setup ruclips.net/video/IpqPej8mayI/видео.html
Thanks JD, I appreciate the feedback. I usually overdo the gain on the audio, tried going lower this time, but did not reduce the background music enough. CS!
How do RUclips manage to get such good star on the edges? I use the same focal reducer but all of them are alongated. I Washington looking for anoche focal reducir which could give me round stars. Whats is your secret ?
Hi @yvangarcia3535, no secret, just collimation and back focus. If you are using filters, you need to add a spacer to the standard back focus distance. I have also found that this telescope is very sensitive when collimating. Although I typically collimate indoors using ASTAP, I still have to tweak the collimation by shooting a rich star field (look for open clusters) and looking at the corners. I still get it wrong quite often, but I'm getting better at reading the difference between a corner being too close vs too far. Just the same, I have not yet been able to get a completely flat field of view. Maybe a better flattener would help. Clear Skies!

Looks like it came out great wish I'd bought the quadband instead of the triband but hey ho it works ok I guess.
Clear skies!!

I'm at 36h with the L-Ultimate and want to reach 60h before I start processing because the OIII is so faint. Good job.
Let me know if you post it!
Very nice video and great capture!
The sound level of your voice is quite low in my opinion, especially compared to the music. Great job anyway! CS!

I also have a 6se but I use alt az.
It really is a very versatile scope! CS!
👍🤩!
May be you are using dithering ?
I do, but limited because the NexStar mount takes a long time to settle.
