Hi Roland You refer to the seeing as rated by Clear Sky Clock. Is that a free web site or a subscription service ? Do you have any techniques that you use yourself to estimate what the seeing is ? I w

Hi Vincent There have been several discussion threads on the forum concerning the type of grease to be used (search for messages about "grease"). One of the recommended types is Aeroshell 33, but Rath

Hi Nick There are two distances that you must be concerned with: the distance from the back of the flattener to the CCD chip which is fixed, and the overall focus distance for which you use your focus

I wonder if maybe they have already switched to a different supplier. The cable on my keypad (purchased in 2017) has a matte finish and is very flexible. When did you buy your controller ? Unfortunate

I know that the A-P folks have been busy. I was notified on the 19th that they have a 92mm Stowaway for me. Best Regards Michael Hambrick ARLANXEO TSR Global Manufacturing Support PO Box 2000 Orange,

Very good comparison Roland Thanks I have read that the signal to noise ratio is higher for long exposures, but is there a limit to what can be accomplished with long exposures ? What happens to the s

Another question: Is that a DOVE15 on top of the 160 rings ? I sure wish you still made those. Best Regards Michael Hambrick ARLANXEO TSR Global Manufacturing Support PO Box 2000 Orange, TX 77631-2000

I LIKE the laser pointer holder. That is a great idea ! Is that designed specifically for the purpose, or is it just one of the dovetail finder brackets ? Best Regards Michael Hambrick ARLANXEO TSR Gl

Hi Kevin I think Astro-Physics makes most of their own cables. You might be able to get them to make a modified version of the CABLPF to put whatever kind of connectors you want on the end. I like the
