102mm achro for cheap
Posted 10 July 2013 - 10:07 AM
Thanks Laz, I have used a digital level for the Alt with a
Az circle, this coupled with a Orion 8x50 raci finder, very
easy and fast to find objects, just didn't like doing the look ups for current alt/az readings but have not tried
the app you mentioned, will have to check it out.
I roll a dew shield with black art paper and tape it together. It retracts backwards onto the tube so I can still use the lens cap. Yes I added an az circle plus an alt scale and bubble level,-- works well for finding dso's with Sky Safari app.

most hardware type stores sell them I believe.
Thought about getting one, however by the time I pay for shipping to Canada and customs have their share it becomes a $200 OTA, not worth it, for me anyway , what annoys me is that you see all sorts of great deals in the USA but in Canada its the old take it or leave it with the prices,DA.

Per the Celestron manual (at this link) on pg 15, the OTA weighs 8 lb. Be sure to add the weight of accessories (finder, diagonal, eyepiece, rings/dovetail, dewshield, etc.) to get the full weight for your situation.
Does anyone know how much the OTA weighs? I tried to find out on the net but none of the specs list the weight of the OTA. ...

I didn't care for the OEM focuser so I ordered a GSO dual speed Crayford and it will be here early next week. I looked at several mounts and wanted a goto that I could afford. So I ordered a iOptron Cube Pro. The tube out of the box weights 6.5lbs. The new focuser adds about 5oz to that weight. I'll be using 1.25 eyepieces most of the time. So the Cube Pro should handle the weight ok. The advertised payload for the Cube Pro runs from 6 to 12 pounds. iOptron started out saying 12lbs and now says 8lbs. I've read a few reviews with the owners running 10 to 16lbs and they weren't having any problems with the mount. I'll see how it handles the tube length and balance.
I also ordered a longer vixen style dovetail and 2 100mm rings for it. I can then mount the tube in the rings and be able to balance it on the mount better. If this all works out it will be a great grab and go scope.

I haven't had a chance to get it out and observe with it but tomorrow night is supposed to be clear again so I'm hoping to get some time at the eyepiece then.

It's a 4", and this should help me understand what I can see with that aperture. I understand I'll have CA, but at this price I can deal with it.
100mm rings on order. Since I can only use one scope at a time (I have one mount) the OTA can borrow the upgraded diagonal from the 80ED.
