Hi Alex, Not sure why we'd be harsh - it's a good shot at a deceptively difficult object. Given the limitations you're working with it's a great shot. Darren. ...
Nice one Alex, the color came through well. On my monitor the black point looks a little clipped - maybe having a slightly lighter background would reveal some...
If I stacked 70 images on one night and then 30 images taken from the other night, and then combined two resulting pictures (first stack of 70, second stack of...
Hi, I'm weighing some alternatives for a mid-fi mount upgrade (really, Jeff, I *swear* this time! <g>), and am wondering if anyone in TAC-a- ritaville is using...
Hi Jim, I owned an EM200 many years ago. I now own an AP 600EGTO, which is based on the same overall design. The EM200 had a significant improvement over the...
Hi Paul, Thanks for the informative reply. Wow! -- 5 sec @ 2x!?!? That's VERY high. Though nothing can touch my CG-5 for Worst in Show in that regard. :) ...

Glad it was helpful. Keep in mind, that's just one sample out of a whole lot more. I think my EM200's problem was in the motor gearhead reduction assembly, not...
Richard Navarrete tried to sell a C11 recently on TAC but I called him out as a fraud, because the instrument had been mishandled and broken several times. Do...

Umm, errr, thanks for the warning. I don't begin to understand the depth or breadth of this inside joke, so I'll just leave it alone. :) As for DEC backlash...
Jim, The MI250 is a great mount and is about as portable as an AP900 or AP1200. Its kinda of in between in size. The Dec assembly comes apart from the RA ...
I have Hap Griffin Astro-Cable for canon 350D, any idea where can I get an adapter to use with 20D ?? anyone can sell one ? I am not too friendly with the ...
... Purely a joke. You're witnessing my smartass streak. Richard and I are good buddies and it does him a world of good to have his nose tweaked once in a...
Although I have tried rotating the camera and moving the target around on the chip, I simply can not find a bright enough guide star when shooting Ha from my...
Hey Paul, I had/have one somewhere, I had trouble finding bright enough stars to guide by so I ended up using an 80mm achromat as a guidescope. --Ivor _____ ...
Another option would be to use an off-axis guider and external guide ccd, placed in front of the filter. You'd still have the hassle of rotating it to find a...
I had no problem guiding with a 200mm FL camera lens and the ST7E main chip. As you probably know, the guiding software calculates centroids across the ...
Hi All, My TOA-150 scope arrived back from Texas Nautical from its re-collimation. To cut a long story short it's only about 50% fixed and is on its way back...
Hi Paul, I don't use an e-finder, but I do have a simple 200mm/50mm acromat with a ST402 (based on a Chris Patterson/Cloudbait obs. design). This design does...
Nice image, I can't see why you returned the scope again! Make sure you are in 8 bit mode when making your final adjustments for the jpeg because if you are I...
Thanks, John, Ivor and Darren. I thought about an OAG and was reading about the (expensive) Astrodon ROAG and MOAG units. It seems that I need a separate guide...
... I'm sure everyone would like to see that. I definitely would. Paul ____________________________________________________________________________________ ...
Hi Ivor, Unfortunately star testing still shows the scope is significantly out of collimation.When focusing most of the star light is offset from the center of...
Hi Iver, Sorry for the late reply. On my refractors I use the robofocus motors (the sleeve coupling they provide is very useful) with a home-made controller...
Hi Paul, Its in AstroPhoto Insight vol 2 issue 4. Backissues can be found at http://www.skyinsight.net/astrophoto/current.php The appropriate issue is the Dec...
