How could you, living in Massachetts?

I've had a Meade 90 Mak (I gave it away) and have a Questar (which I'll likely sell). I prefer refractors in that size.

Have you ever observed from areas about 2.5 hours West of Manhattan (e.g., just East of Hancock, NY off Rte. 17)? Are the skies clear enough there to be a useful observing location?

Hello all! I live in midtown Manhattan which probably has some of the worst light pollution in the world. I am limited as to what I can see, the planets and the moon mostly (I did see the Orion nebula and the Jovian moons last night with 10x40b Zeiss binoculars on the roof of my apartment building.)

I want something small and portable which I can take the roof or walk to Central Park with. A 90mm Mak might fit the bill!

I am trying to decide between the two common ones. The Celestron C90 and the Orion StarMax 90 tabletop.
I have read good things about the Celestron, but not as much out there about the StarMax. The StarMax is $50 more, but comes with an extra eyepiece and a simple mount.

Any opinions on choosing between the two? Any other diminutive ones I should be looking at?

Thanks!
Rafael




I just sent you a PM.

John-(return PM sent)
The only observing I have done so far is through my binoculars, this will be my first experience with a telescope. The Amateur Astronomers Association of New York is having viewings in Central Park on December 20 and 21st. I hope to go, talk to some people to find how they deal with the city!

Does anyone know if there have been side to side comparisons between the Orion SkyMax 90mm and the Celestron C90? I know they have same Chinese manufacturer, but I assume they could have slightly different specs...

The differences optically are very minor between these two--and the other Chinese MCTS, as well. I would give a slight edge to the C90, though.

I have one of the new C90s and it has suburb optics, and seems to be built like a tank. The finder is junk, however; I tossed it and installed a "Mars Eye" red dot finder from an old Stellarvue scope. Actually, pretty much all the accessories which came with the scope are junk except the carry bag, but the whole setup was only about $160 so definitely worth it.

Bism (?)

Thanks for posting the link to the Central Park Observing blog. Very cool. I have not seen that before.

There was a question asked about Hancock NY (off of Rt.17) and how good would that be to observe. In a word great! If you look at the light pollution maps you will find that it is in a blue zone and as dark as it gets around the Big Apple.

The place I go to, also in the blue zone and not far away is Stone Tavern Farm I was there last month on a weekday and had it all to myself.





I try to get there once a month when my schedule permits. It is a private horse farm and more and they charge $20.00 a head to set up and camp. This time of year I just set up and stay in a motel. If you have a spot in Hancock already I would say you are set though the horizons at Stone Tavern are excellent.

As far as observing in the city; well I observed from the corner of 72nd and 3rd last year and looked at Jupiter and the Moon and drew a crowd. My girlfriend, who had never seen Jupiter before noted that the telescope is a chick magnet. Better than a dog or a baby!

I also take peaks from my apartment windows which faces east and south and is ok for a fix. This past spring I got to the roof to observe the transit of Venus.



That is a 92mm TMB on a Universal MacroStar that I like for the city as well as this.



66mm WO that I keep set up all the time.

Good luck and I hope to see guys around.

Al

Al- Bism was a fellow I responded to on a previous page...
Thanks for all the pictures! Stone Tavern Farm looks wonderful. I need to get out of the city more often. Maybe I should try Metro North to Cold Springs.

You can see the sky from 72nd and 3rd?!

Al,

Thanks for the local info.

I did notice that the area around Hancock, NY has dark skies (according to the Dark Sky app). Do you know what the average night time cloud coverage is? If I moved to NYC, I'd be tempted to get a parcel of land outside the city if the weather was cooperative.

There is a package under the Christmas tree with my name on it that looks suspiciously like the dimensions of a C90 box!!!

Good luck! I may end up getting the Orion StarMax since it comes with everything needed. Although I wish it came with the nice little backpack!

I'd opt for the Celestron tho both are probably ok. You shouldn't be in Central Park at night at all for anything much less with a scope. Opt for the rooftop or balcony. Open window observing is subject to flaring and bloating from temperature differences but if its dogging at you low power is passable here. Obviously thru the window is an astigmatic night mare.

I will say a 5" sct by Celestron takes up no more room on an apartment than a C90. It's extremely negligible. It costs a little more but it's still cheap and the angular resolution and magnification carrying capacity is substantially higher.

Pete

There are people who set up in Central Park, with telescopes, at night on a regular basis.

The mayors girl friend walks her dog there by herself at night.

New York, I think, is very different from what people remember it being. It is the safest big city in the US.

I myself walk through the park often on my way home.

I have a Questar 3.5 (see sig) but I prefer binoviewing w/my C5 and Brandons. Also use a BIPH w/that C5. Real portable...fast setup. Love it.

Unfortunately all I see from my apartment windows is the next building over! Also, I would really like to be able to take the scope with me when I go traveling. I can always get a larger one!
