Buckeye Stargazer Upgrades for the Explore Scientific ED102

- I had to put the Celestron C9.25 SCT "on the shelf" as I solved the ZWO camera fan vibration problem and had an unexpected need to use my Explore Scientific ED102 refractor while I still had some clear nights. I've added some Buckeye Stargazer 3D printed plastic parts (from Agenaastro.com) to the ED102: filter masks for the ZWO filter wheel and a support bracket for the Pegasus Astro Ultimate Power Box. I also added the new ZWO ASI220mini guide camera to the ZWO OAG. Check out the images of SH2-170 (Little Rosette), SH2-142 (The Wizard), and the Cygnus Wall at the end of the video!
I appreciate having the opportunity to learn from your very practical experiences!
Great! And thanks for watching!
Hi James, been re-watching a lot of your vids. I'm currently putting together a first gen Redcat 51 with EFW, OAG, etc. on a EQ6R so your vids are quite helpful. I'm in a Bortle 2 (Maine) so if I get some clear skies theoretically a good spot.
Bortle 2! I can't even imagine what that must be like. On the other hand, I can imagine what shoveling all that snow is like. Thanks for watching!
Hi James,
Good video as usual.
I just bought the Antlia 4.5nm 2" mounted SHO filter set. I see you have the 3nm set. It would be interesting to see the comparison of the two. I am testing them with the new Player One Poseidon mono camera and so far, am very pleased with the Antila filters ... actually, blown away. That embossed dust bunny "on the flats is rather interesting. How many flats did you take and what was the time exposure for each? (an inquiring mind wants to know" thing.) It looks like several clear nights (with no jet stream) heading our way with a waning crescent moon ... wow, we need to jump on this. You might want to fire up the SCT again and try for Jupiter, Uranus, and Neptune.
I bet you’d be hard pressed to tell the difference between the 3 nm and 4.5 nm filters. I do like the Antlia filters - they seem to hit a nice performance vs price point. Those flats were 0.5 sec, I think.
Oh, and I took 50 images for the master flat
Thanks for sharing. Great video.
Thanks for watching!
hi James! nice add-ons!
happy hunting for those fainties!
in your opinion, is it worth getting the 0.63 reducer for a C11 or is it just a waste of time ?
Yes. Very handy little doodads. Thanks for watching!
I had exactly the same problems: vibrating fan on camera and inaccurate filter wheel. This screwed a lot of hours astrophotography.
Eventually, I rid of both; then got QHY pair (camera-filter wheel). All problems are gone.
I have no more ZWO equipment and no more problems with rig.
Well, I’m not quite prepared to ditch all,of my ZWO equipment. For better or worse, I’m stuck with it. Something to consider down the road, maybe.
@@Aero19612 Fortunately, their re-sale price is very good, since popularity of ASAir. Basically, I lost almost nothing due to resale and little bit higher cost of ASI294MM compared to QHY533m. Moreover, despite having qhy268m, I mainly use 533m camera. Superb product!
That’s good to know. Thanks
Nice work Jay?!
Thanks, Bill. Didn’t want the fan vibration problem, but it was nice to use a refractor again. I gotta get back to you on the 3D part we’ve been discussing. I still think we can make something fit. I’ll do some vibration analysis this week.
Curious -- When moving the ultimate power box do you move the small dovetail bar with it (i.e., take it off the L bracket) or do you have a Vixen bar on each mount and simply unclamp the V bar clamp with the thumbscrew?
I move the dovetail bar with the UPB attached. It's just the one socket head screw, so it's pretty convenient.
Nice!
Thanks for watching, Rob!
Does the slightly larger sensor size of the asi220 show up on the small prism of the ZWO OAG ? And does it capture more guide stars? I am thinking about upgrading from the 290 as I am starting to run into problems finding enough guide stars on my iOptron HAE69 at a 1500mm focal length (as it requires .5 to 1 second guiding).
It should - the small ZWO OAG mirror is 8 mm x 8 mm, which is larger than the ASI220 sensor. For my ED102 (700 mm), I don't have to even think about the guide stars and OAG view. The ASI290 I had been using was perfectly fine - I just needed a new guide cam since I decided to use the WO Uniguide guidescope with the other two refractors. For your 1500 mm focal length, you can certainly use the extra sensor area of the ASI220 (I use the ASI174 with my SCT).
@@Aero19612 Thanks for the input. I ended up getting the ASI220 and both the sensitivity and the larger area made a substantial difference. On the Bubble Nebula on one side of the meridian I was only able to pick off one guidestar with the 290, but I was able to find multiple guidestars with the 220.
@@dirkfierce2525 Great! I’m glad it worked out for your setup.
And, do you shoot a separate night for each filter or all filters each night?
I generally try to shoot with one filter and get all of that data. In the real world, however, clouds might move in and I'll lose a lot of data for a given filter. Then I'll have to "get caught up" by sharing time between filters on the next night.
Thanks. I saw one youtuber set up NINA to run through each filter and repeat that block run through but doing as you do seems more effective.@@Aero19612
What is the math for the ratio of O-H-S?
Not sure what you mean by the "math" for the SHO channels. If you're asking do I have a formula for how much imaging time to spend on each filter, the answer is "no." For SHO, I generally shoot about an equal amount in each filter. You could argue that OIII and SII are fainter and need more time. Or, alternatively, that Ha provides the detail so shoot more with that filter.
