Nice setup Chris. Do you have issues with vibration when observing from that deck?

Are those railings up to code? looks like one could topple off your roof either in the dark or in a drunken stupor




I've learned how to "walk softly" well enough to prevent deck vibration from being a problem when it's just me up there during an observing session (the great majority of the time). When I have guests observing with me, sometimes I have to politely direct everyone to please sit with quiet feet except for the person viewing, and I often have to gently cajole the person observing to walk softly, small steps, to avoid inducing vibration visible at the eyepiece. I'm more or less successful in getting sufficient happy cooperation from everyone, but fortunately when I'm up there by myself, it's second-nature now to move around without inducing vibration (especially when I'm barefoot in warm weather). Wind-induced vibration can, however be a problem, though I get enough relatively calm nights that this isn't a severely prohibitive issue; on nights with a stiff breeze, I content myself with low-power panoramic views in an Ethos 13, 17, or 21.

As to the railing and the deck, my house (on a coastal barrier island) was built "Hurricane Andrew" structural standards in 1995, when memory of that event was still recent. Gradual deterioration (on the scale of one to three decades) from harsh marine weather and sun exposure is a significant long-term issue, but the inherent structural soundness of the deck is very solid. My builder is known for high-quality no-corners-cut work, and houses built by him out on the island have a bit of premium value because of that. The railing is tall enough that falling off isn't a risk unless someone gets foolish enough to climb up on the bench up onto the roof itself at night. Not something I encourage to do unnecessarily, even in the daytime.

Hi Mike Clemens,

I watched the video with interest. It's nice to be young and strong!
It don't last forever, unfortunately!
I don't have an observatory, so I mount my 155edfs all the time. One thing that lightens it and makes the job easier, is to mount the rings first. Then put the tube in the cradle.
Nice observatory and mount!

Ross

Nice one! Some TASCO telescopes are top notch! I do not know why they do not advertize their good stuff. Like it is a big secret or something.

Impressive photo of the 200 next to the 175! What a difference an inch makes.

Where's this video that Ross references?

This is the ES 152mm that I use in my observatory for my outreach program. The scope is setup on the second floor in the refractor room. The scope is used for deep sky objects using a Siebert 25mm binoviewer and a Siebert 2" binoviewer. The observatory is up and running, but still needs to be finished off inside.

This Tasco 10K is around 35 years old so I don't think advertising would be of much use now.

Rolandos, that looks like a very sweet set up. I bet you get some nice wide field views. What mount and tripod are you using?

I see you have a Canon lens attached on there...do you normally attach a camera body to it or something else?
I always get interested when I see other ways people use their camera lenses.

Well finally got my new Sky Watcher Pro 120ED APO last week and the Moonlite focuser the same day. The hand controller on the Atlas mount directions buttons were not working. Orion is sending a new one. Will have to wait for first light with it maybe this weekend.

I use the lens with my Canon 7D and 5D MK-III to take photos of the moon which I print out and give to the kids that show up at the observatory.

A few years ago I bought a 90mm dark blue/purple Meade DS2090 OTA on ebay. If you ever owned one you know it's a terrible scope due to its focuser. I was able to motorize the original focuser but it was still bad.

Hence I decided that it was time for a makeover of the one and only refractor I had. Because I like the look of the Vixen R120Sf that I own as well as the look of the white Vixen refractors I made up my mind to give the Meade DS2090 a similar look.

I replaced the tube with a white one (also from ebay for about $15, S/H included), added a used 2" slightly problematic dual-speed Zhumell SCT focuser (yes, I put an SCT focuser on a refractor), covered the 3 screws that hold the focuser with a flexible toilet bowl ring from Home Depot, added a 2" extension for the new arrangement to reach focus, added a variable intensity red-dot finder by Barska, made a dew shield for the finder, added a weight made of cheap WalMart bearings on the front (they were on sale at $2 each), changed MEADE's logo to resemble that of Vixen's, added my own logo and there you have it.

I do get pretty nice views of Saturn and the Orion Nebula. And before you start screaming about copyrights and stuff, I can change any logo I want for personal use as long as I do not sell the product and as long as it is changed by more than 10%. Read the law.

The modified scope sits on the Astozap EQ mount I motorized and reviewed in other CN threads and it's solid as a rock with the correct balancing I have done.

I know it looks fancy but it's my baby and I like it.

Thanks. It was an interesting project and the end result was satisfactory enough for me. Before the mod it collected dust at some corner of the house. Now I use it regularly and I have started experimenting with older CCD cameras that I attach to it. I know I can get better results with my other scopes but this one makes me feel better. And it's the least heavy of the group... :-)
