TAL 100 RS on a CG-5

Posted By Walter Hamler
Usually the TAL ota's come with rings. The swivel bolt/screw combo they use can easily be removed and the attached to whatever you want, I'm sure.
I use my TAL-100 on the larger TAL-2M mount with a taller center colume. I am very pleased with its stability and tracking accuracy, althought I have replaced all the bearings and relubed/adjusted to tweak all I can out of the unit.

500 mm lens question

Posted By Walter Hamler
That's what it do! You "preset" the other ring to the f/stop you want, then turn the O-C ring from O to C to take the picture. At O the image is brighter for focus.
If you are using with a camera that has Shutter priority metering you can put the click ring to a large number, say 22, and turn the other ring until a shutter speed lights up that is appropriate for the situation.

LONG. AND LAT. HELP FOR NEWBIE

Posted By Walter Hamler
Somewhere north of Lancaster, PA?
If yours is like the Nextar 8 you have to multiply the decimal portion x 60 to give minutes of lat and long. When you enter the lat, ie, 42* 22', you will probably have to confirm + or - for N or S hemisphere. When you enter the long, your first digit will be a 0, ie, 076* 06', then confirm the long is W.
I hope this is correct, as I'm giving the way it is on the Celestron Nextar 8.

NGC4536 LRGB with remote telescope

Posted By Walter Hamler
Hey Ron, can I put in a request for NGC 4565? My favorite edge on galaxy. It was my first introduction to a ngc object in a moderate size scope (8").

panoptic 15mm plus 2.5x tv barlow for planets?

Posted By Walter Hamler
It seems every time a 15 Panoptic is mentioned on this forum the comment is made about its lack of eyerelief. I personally find this not to be true, and I have compared it to Radians, Naglers and XL's. I admit it is the tightest of all the Panoptics, but I find it comfortable (I don't use glasses when viewing). I have not used it with the 2.5x Powermate, but have with several other premium barlows, including the new 2x Powermate. I find the combo in every case to be sharp, to the point that I sold a 6mm Radian that, IMHO, was not as good as the Panoptic/barlow combo.
All this is, as stated, jusy my most humble opinion, which man not even be worth .02.!!

1.25" or 2" Ultrablock?

Posted By Walter Hamler
I would vote for the 1.25 as you will find that those type filters work best at the max contrast output of the scope, and generally that is with eyepieces that give middle range mags, ie exit pupils around 3~4mm. If you don't buy any more 2" filters (ok decision) then a 2" filter would be used on only one eyepiece. With the 1.25 you have the opportunity to use/try on any 1.25 you have or borrow.

What is the red spot?

Posted By Walter Hamler
If you see it in every photo of M-31 then it is most likey a red star, either a red giant very far away or a closer class M or one of the even dimmer and redder variants??
There are lots of them out there and when you come across one in the eyepiece, it's almost like a stop light, that red, so you are supposed to STOP and look.
