Pillars of Creation using the Celestron EdgeHD Telescope at F/10 and Optolong OSC LP Filters

- When using a one-shot-color camera, certain filters will enhance the output of the target. But what filter to use? This video gives insight into the Optolong series of L-type filters and the particular light frequencies they allow. Also, Using a telescope with a super long focal length requires critical guiding. I used the Celestron 11-inch EdgeHD telescope at F/10 to shoot four different targets highlighting the different filters. They are Messier 51 (The Whirlpool Galaxy), Messier 5 (Globular Cluster in Serpens), Messier 20 (Trifid Nebula), and Messier 16 (The Eagle Nebula, containing the famous "Pillars of Creation). The guiding system I used was the StarSense AutoGuider from Celestron and was able to achieve 5-minute sub-frames on each of the targets. At the end of the video is a short music video of the Heavenly Backyard Garden for June 2024.

Great captures Pat. Thanks for sharing.
Thank you for watching my video, Ron
Very nice lot of captures there Pat. I particularly liked the Trifid nebula image. The garden is also looking spectacular. Clear skies.
Thanks, Logan.
You should be getting some longer nights there now.
Clear skies.
Beautiful images there Pat!! Your garden is absolutely amazing! Thanks for sharing!
Thank you
Well done, Pat. I'm in AZ at 32 deg also. And it is hotter. In fact, to hot to image IMHO. Love your thought processes and creativity!!!!
Hi Charles,
Thank you for watching my video(s). Yep, it gets mighty hot in Arizona. I wonder how your heat affects the onboard equipment, particularly the mini computer?
Nice video Pat. You've captured some lovely targets there. That globular m5 looks fantastic and m16 too. Garden is in full bloom though it looks like a lot of work in that heat to keep it so. Clear skies bud.
Hi Rob,
First of all, thank you for joining my channel.
It seems that globular clusters are often overlooked but certainly worth viewing and capturing. What can I say about M16 ... lots and lots of captures of that famous target. Yes, the garden is certainly high maintenance, but it's what I like to do, so I am happy to keep it going. Right now, water is the issue and it has dried up out there and now the temp is in the mid to upper 90s (35-38C).
Clear skies to you, but I see you are way up north so little astronomical dark skies for now, but clear skies anyway.
As you have such a good guiding, I believe you should dare to put a barlow 2x to image the Pillars. Like operating at f/20. Guiding is really everything and if you can achieve it at a long f you can really image anything. Would you try it? A bit challenging, though.. you have an awesome garden as well, and when I saw the fountain there, Liszt's melody from "Jeux d' eau a la Viila d' Este" started to cross my mind.. cheers from Greece.
Hmmm,
That would be interesting to try.
The garden is a great stress reliever and I enjoy working it. Thanks
Clear skies
Hey Pat. Some very nice images! I'm wondering, how are you doing 5-minute subs in a light-polluted city in broadband? Wouldn't background sky glow limit you to much much shorter subs, even with the LP filters? Just curious. Thanks.
Hi Grey,
I am in a bortle 4.5 zone. When looking toward the E-S-SW, I am looking out toward the ocean and marshes. I do get some light pollution when looking W-N-NE when looking back toward Savannah. These LP filters are certainly a game changer for me.
Wonderful video, thanks Pat. M5 is my favourite globular. I have a C11, too, and I'd like to ask you which imaging camera are you ising? I'd like to know the pixel scale especially, thanks.
Thank you for watching my video.
The camera for this video was the ToupTek SyyEye24. It has a massive pixel size of 5.96 microns. The other OSC is the ZWO ASI 071 which has a pixel size of 4.78.
My monochrome camera is the Player One Poseidon and has a pixel size of 3.76
@@HeavenlyBackyardAstronomy Thank you so much Pat. I have given a fuller reply covering this topic in your "Celestron's StarSense AutoGuiding Setup for Perfect Guiding" video.
Clearr minds & happy skies, Simon
The Trifed is out of question at 43 N, below 30 degrees at best. I've been trying to image the Eagle, as it's skirting 30 degrees after midnight for 3 hours. Having technical difficulties with asiar firmware upgrade forcing coordinates of China WTF! Imaged it with Seestar. I'm embarased to say😮. (As you said, can't NOT image on a clear night). I tried again this morning with 840mm Askar 120, but clouds rolled back in. Your pillars are amazing.
You think 2800mm is even do-able in an urban environment with the thermal convection of all the city surrounding me?
Too many filter choises for broadband. I'm just using UV/IR cut on galaxies and clusters. Idas GNB, and now your suggestion of L-Pro. What to do?
Hi Mike,
Yes, at 43N, your view of the Trifid and Lagoon are very low. I have no knowledge of ASIAIR but would bet it has something to do with the time zone setting ... perhaps a negative sign need for longitude??? I am very impressed with the Optolong L-Series of light pollution filters. I tried using only a UV/IR filter, but it just allowed way too much of the polluted light. The 2800mm FL scope is excellent for planetary but at least with me, also good for certain nebulae, and great for globular clusters and some galaxies.
Hopefully, those pesky clouds will leave you along during the short window of astronomical dark skies you have this time of the year.
The LP, and moon gradients are brutal with UV/IR. graxpert to the rescue. I've spent WAY too much lately on this hobby, but maybe the L-Pro is affordable?
3:13 Is that a 10 element 2 meter Yagi and a 70 cm Yagi you have there, are you a ham operetor, if so I am SM3RWZ.
No, that's my TV antenna. I get 38 local channels from it. Works like a champ with my Tablo DVR
OK! Thank you.
