I recently purchased a TV-85 on astromart, and I'm having extremely severe problems with lens flare. This happens for both normal observing and photography (see attached example), so I know it's not the focal reducer, diagonal etc. It has to be the scope itself.

I've performed the obvious check of looking for uncoated surfaces inside the tube but can't see anything that would produce such bad internal reflections.

Is this common with the TV-85's? Is there a simple fix or do I have to send it back to Tele Vue?

I've also looked for contact details for Tele Vue but can't find any on the net. Is there an email address used for organising inspections/services?

I'm just starting to get going with my astrophotography, and once I solve a few minor problems with my scope (see thread on TV-85 lens flare) I'd like to start stacking exposures of faint objects.

I hear that everyone uses Registax for planetary images. Is there an equivalent program for faint objects or can you use Registax for that as well?

What I'm after is the easiest, cheapest way of stacking 30sec-5min exposures.

Last year I bought two EP's from a guy called Milton Esquinaldo. They never arrived and I've tried to track him down since but his email addresses don't work anymore. He has reviews posted on cloudy nights so he's a legitimate astronomer, but I can find a current email address for him.

I think he lives in the Florida area.

If anyone knows Milton or has a current email for him, could they please send it to me outside the forum, or alternatively send him my email address.

Paul,

I'm amazed you can get a noise free image at such long exposure and high iso. Can you elaborate as to how you have done this?

Also, do you have problems with a red fog apearing on the right side or lower portion of the frame on long exposure? I see this effect on my d60 at iso400 after only 50 seconds.
