Back in the late 70's I ordered a Cave reflector.Thomas Cave was in trouble finacially AND sick. To make a long story short,I didn't think I was going to get...
Thank you for your supportive words Mickey. I think lots of us with an order at Discovery think as you did then. We want a Discovery, no matter what and we are...
Johan,nice to meet you. I have my own observing agenda called "Burnham's Club". I have tried to observe everything in the Burnham's books.I have most of the...
Hello Mickey This is a very nice tip you gave, myself I found an interesting book called "the 110 Best of the NGC" by Paul Dickson. Very handy tool for...
Johan, Rule one is that when you receive new astronomy equipment it rains for AT LEAST three weeks..hahah!! My (humble) advice is for you to buy a OIII filter...
I never get used with those groups and their message. 2 empty message posted and I cannot remember I sent them! Wel... What did I do wrong?!?!?!! Mikey, I...
I also have a 12.5" f/6 split tube & I'm able to reach focus with my Sieberts black night binos & 1.8x OCA. Loosening the primary mirror equally on all three...
Chris, I have had good results using the lens assembly from a Meade 2X Telenegative (barlow) where the provided OCA did not come to focus. Try any barlow lens...
Chris, I had to move the mirror in 1/2" on my 12.5 to use my 31 Nagler. I soon found out I needed that for my TV Binos too and didn't know it at the time....
... Has anyone estimated the reduction in fully illuminated field this modification produces? I'm assuming that it's minimal since so many are doing it. ...
John, The secondary mirrors I have seen in Discovery Dobs tend to be on the large size anyway and as you pointed out any change to the main mirror would be...
Johan, If you havent looked at the Veil in Cygnus with a UHC filter you are in for a surprise.Work your way to the field of the object without the filter and...
John, There is no light reduction. When you move your mirror in some to obtain focus you got what you got. After you move it (your primary) in enough to focus...
Hi Mickey, "you're in for a surprise" reminded me why I bought those filters in the first place. I was reluctant using my OIII-filters on small aperture...
Well, thanks for the replies all. What I did was quite a bit simpler to reach focus with the binos. I had some really cheapo color filters laying around so I...
... move ... Chris, I also had stiff azimuth motion with my 17.5 pdhq and got great results by putting 2 or 3 plasic milk jug washers on the center bearing. In...
Hey everyone I am new here and I have some questions about the 15" split tube. Right now I have an Orion XT10i and I was thinking about upgrading the the...
Andrew, I have owned the 15" Discovery Dob (the split-tube wasn't available at the time) and I absolutely loved it. I also owned the Orion 10" XTi and I like ...
Hey Bill, Thanks for writing, I will check into the Discovery DSC. I am excited about the future upgrade and I am trying to watch astromart for any used...
Andrew, Sorry but the site for some reason will not allow me to upload photos. I believe if you look within the group under photos, a photo(s) of "Big Brother"...
I haven't done this myself but probably the cheapest way is to by an Orion 6" Intelescope for $380, take off the COL parts and adapt them to your 15", and have...
An interesting idea. However, I would be most curious to see if the encoder compatibility is there from the physical installation standpoint. I have owned/used...
Here's what I did for my 10" DHQ. I purchased a pair of used encoders and a DSC computer off Astromart, and got a hardware installation kit directly from...
Hello Ken, Agreed. I once did the same thing. From what I understand, the unknown in the equation these days, is whether or not 'anything' can be obtained from...
Moving the encoders over is the "adapt" part of project. I haven't looked at an Intelescope setup so don't know what would be involved. I'm sure it's...
