    Well I took some photos and played around with it some more. still can't get the red dot to fit in eyewhole of collimator or see it near on solomark one, but I see a bunch of red with the Aperatura one that came with it. I also realized that the battery was low in the collimator and replaced it and saw that it was much stronger. That could be one part of the problem. Also with my aftermarket solomark colimator and the collimator that comes with the aperatura, I noticed an alignment difference. They are not the same when put in the view finder and when I trotate the solomark one in the eyepiece it does not sit still rather uneven circles. The aperatura one seems to also hold firmer in there.

    I messed around with the back to the point the primary mirror was loose from the screws (not planned) but I do see how it operates now and how much dust it collected so far from just a few months of use. I placed the mirror and knobs back on and back to this point in the photos. i will play with it more after dinner and hopeflly I can get it aligned by later this evening. I can align the secondary mirror no problem but could the angle be mesed up since I messed with the main center screw and lossed it? One thing I did learn and thanks guys for pointing that out is the locking knobs are the white ones, before I was adjusting all of them until it aligned.

    It sounds like your solomark collimator is out of collimation. It could be the one that came with your telescope may be as well. I know mine was when I got it. To test it, I got a block of wood and nailed two sets of nails in a "V" pattern to make a cradle, dropped the collimator in it and pointed it a wall about 12 feet away. When I spun it, I could see it making slow circles on the wall so I knew it was out of alignment. Good news is, with a little allen wrench and a lot of patience I was able to get it pointing straight again.

    That is possible. Pretty sure I read somewhere that there should be no need to touch that center screw for anything, and I see a lot of thread showing there on the secondary adjustment screws in your last two photos. I'll have to look at mine when I get home for comparison, it may be normal. Its hard to tell from these photos also but you'll want to make sure the secondary is centered directly under the focuser as well.

    You really worked over those primary black and white knobs!

    I found the Apertura laser collimator to work satisfactorily for me.

    Once you get the procedure down you'll find it easy.

    Thanks Don & Greg

    I will try that test with my collimator and see if I can collimator my collimator . As of last night the two collimators when inserted and aligning the secondary mirror show about 1 1/2 inches difference. Also thanks for checking the secondary. I will make sure when I get back it is right under it.

    Here is the view though the focuser before I went out last night with the telescope (I couldn't resist since it was clear and next few days rain plus just to get some footage of how it performed as it was.) Saturn had a fuzzy glow on the ring outside of it and Mars Had a some outer glow as well but did not seem as sharp as I had it before.

    Here is the view of the Aperatura Collimator when it was in to get the results of the above photo. It tried to get it to the hole but just see the red light scattered.

    Thanks for your help again guys.

    I built that V rig and tested both. The Aperatura was perfectly aligned and the solomark drew circles about 2 inchs in diameter. Thanks for this suggestion, now I know why I couldn't get the light to shine back in the hole. I see what you mean my patience when it comes to aligning the laser pointer. I have the allen screw and have been at it for a while. So far the best improvement was to get it the diameter of a quarter and other times as large as a plate lol. I'm gona keep working on it but on my spare time since I know the Aperatura works and I haven't really gave that too much time yet. I also ordered a celestron colimator eyepiece. I figure I could use that along with the Aperatura laser to fine tune it. And it was the only one that would be delivered by tommorrow as the skies should be clear tomorrow & Monday night. It has been nothing but cloudy or rain here this past weeks with an average of 2 nights of viewing per week.

    Thanks again for the help with this

    All is good now,thanks for the help everyone. I received the Celestron Collimator eyepiece for $30 and that seemed to really do the trick for aligning. My secondary was way off. Also I used the aperatura laser. That seemed to be slightly different results, but I am gona go with the the results from the chesire eyepiece since that aperatura laser light was so bright and I played with the allen screws a tad. Also I contacted Svbony (not solomark as I thought). I emailed them about the issue and how I couldn't align it even with the allen screws and they are sending a new one in 5 days or so, no questions asked free. Great service on their part. So now I just got to wait for somewhat clear skies.

    My next job is gona be flocking because when I saw how dirty my primary mirror was, I knew it needs a good cleaning so while the mirror is out might as well flock. I was just affraid before to take it out, but when working on it for the collimation and it came out, I figure might as well do it, plus I am now familiar with collimating it from ground zero. I'll post a flocking thread with my questions as I am sure I will have many lol

    Awesome news Butcher! Glad everything is falling in place and that we could be of help.

    Flocking is a good and fairly simple upgrade you can do, its not really that hard if you come at it with a plan. I did my 10" Skyline last year, came out pretty good. Some of the questions you have, may already be answered in the thread I made:

    Flock. Not the bird kind.
