Hi All, Although I've been a long standing member here, I feel I'm starting from scratch again so please bear with me. I've owned a VC200L/GP-DX for just over...
Hi Sean, I use a very similar set up to you. I have a VC200L mounted on a GPD2 and find it ideal in terms of weight. Comparable scopes are the Celestron 9.25...
Cheers for your response. Yeah it seems like tech really hasn't changed that much. Optics-wise I can guess that there's not much that can be changed there. I...
Regarding goto kits any eq5 type kit should be an option. Synscan EQ5 upgrade is what I use. The bonus here is it lets you use the EQMOD software to bypass the...
I recently replaced the spider of my VC200L with one made from thin sheet steel. I plan to tell you all about that when it's done and tested, but I'm now...
OK, I take back what I said about only being able to see the edge if my eye is way off center. That was a bad observation. Still, it's darn near impossible...
hello, yes this is the same in bin2.... difficult to choose between the two camera , the kaf1603 is a real very nice ship with a higher quantum efficiency.......
I have used both cameras with my VC200L mostly for photometry. The ST9 is more sensitive and will download a little faster. My ST8 doesn't have as flat a field...

As most of you VC200L owners know a well known fault of the VC200L is the large diffraction spikes and squarish looking or ruboid stars due to the excessivly...
I have an odd focal reducer issue. Essentially I'm getting a diffraction spike centered on the brightest part of the entire image. Hard to describe, so...
FYI, I have solved this for the most part. It was light hitting the spider vanes. Why the sensitivity to focal reducer position is a bit of a mystery... but...
Okay, a while ago I ordered a Vixen VC200 telescope. With the help of someone from this list (thank you! you know who you are) I got a replacement spider vane...
At last I managed to have enough time to process my “first” image took with the VISAC and its focal reducer. It is also my very first time in putting a new...
Thank you Olivier! I put a Starlight focuser on mine and it is perfect. Now I have to find someone to mill my spider vanes. Nicola ... -- Nicola Sky Monsters -...
Thought I would pass on to group first for anyone interested in purchasing a used but in excellent shape VC200l. Comes with rings, focal reducer, finder with...
After my good start with M33′s 7 hours integration time, the same night I had three hours of dark left and didn’t want to spoil them. Therefore I started...
Hi Nicola :) very nice picture taken with the visac, amazing color and perfect balance for me ;) I must show my M51 in grey scale, think in few days :) olivier...
