Low Cost Equipment Upgrades
Monolux 60mm Lens Upgrade
Project Cost: $20.00
Time Required: ?
I made many upgrades to this scope that my dad got for me in 1963 - the one that I want to mention is the new 60 mm objective lens. I certainly misused and manhandled the old one over the last few decades. Cleaning it without keeping the orientation of the two glass elements, etc. etc. I ran across a 60 mm objective, with 700mm f.l. at the Apogee internet site. It was a whopping $20.00 for a new objective, and I went for it! I have a few good eyepieces, a 12.5 mm Ortho for planets, a new Orion 2X Shorty Barlow. Let me list a few things that I can see now, but never could before: Cassini's division in Saturn's rings, Jovian moon shadow transits, clean separation of castor A and B (separation 2.2 arc-sec), M1. If you want to try this upgrade, I would heartily recommend it. Apogee's site is: http://www.apogeeinc.com/ by the way, they also have f/15 60 mm objectives and a few others.

Lens Cap for Orion Sirius Plossl Eyepieces
Project Cost: $1.40
Time Required: 1 minute
This suggestion may sound trashy at first but it really works. One of my pet peeves about the 40mm Sirius Plossl I have sitting in my case is that it did not come with a lens cover for the top portion. Even though it sits in my closed case I have noticed over the year that it collects a disproportionately high amount of dust. A few days ago I was sitting around drinking a Diet Pepsi (1 Liter) and I noticed that the cap was about the same size as an eyepiece. I gave it a shot. The cap to a wide mouth Pepsi One liter fits perfectly as a cap to the Sirius eyepieces. Make sure that you clean and dry the cap before using it on your eyepiece. This has saved me time and a little bit of money and overall I am happy that my eyepiece finally has a cap.

1 1/4 Inch Mirror Diagonal
Project Cost: $30.00
quick upgrade for those department store telescopes that come with the .96
Lenses. Picked up a Meade 917 used from Astonomics. Price about $30.
The views of Saturn and Jupiter were muchd improved on my Meade 60mm after
making this upgrade. Made a Christmas present usable.
