Great Telescope easy to use Fantastic to use

Having been in Astronomy since 2018 I purchased this particular Telescope because I like to see the Night Sky. I have seen Stars and Star Constellations and many bright Planets including Jupiter and the Moon . I also bought the Celestron First Scope Accessory kit and it includes an H12.5 and a H 6MM Eyepiece plus a CD and a carry bag plus a Moon Filter and a 5 X 24 Finders Scope & Bracket. I also like that the Telescope includes an H 20 MM and a SR 4 MM Eyepiece. Although the Celestron First Scope Accessory Kit comes with a 5 X 24 Finders Scope I bought a Celestron Star Pointer Red - Dot Finders Scope and I attached to the Celestron First Scope I will keep the 5 X 24 Finders Scope & Bracket as a Spare Finders Scope. One good thing about this Great Telescope is it's on a Dobsonian Mount and all you got to do is loosen the Lock Nut and you Select, aim, point and focus and put in your desired Eyepiece. and you just go up and down and left & right. You don't even need a Tripod you can just put it on a hard surface like a tray table or a pick nick table. It's really a fun Telescope for Beginner's and experienced Astronomers.

Cute Grab and Go

OPT is a trusted name in Astronomy with their fast service and unconditional full support. The Celestron FirstScope is truly a great starter scope because it fits under the arm, is simple to use, and has no mirror adjustment or calibration points. Far better views will be obtained with aspheric glass eyepiece replacements. I added the finderscope with resin lenses as it essentially weighs nothing and does not upset scope balance. The little Dob mount is smooth as silk, The telescope is a legend and an icon, a true collector's item, and great for engaging in "no-fuss" astronomy. Highly recommended!

A Great Telescope And a wonderful Learning Experience

I have had the Celeston First Scope and it comes with two Eyepieces an H 20 mm and a SR 4 mm Eyepiece both are Great Eyepieces. I also bought the Celestron Firs Scope Accessory Kit. The kit has the following items to make using the Celestron First Scope very enjoyable. The Kit has the following Astronomy items. An H12.5 mm Eyepiece and an H 6 mm Eyepiece, a Moon Filter, a 5 X 24 Finders Scope & Bracket and a Nylon Carrying Bag it also has a Bonus Astronomy Software a CD Rom called " The Sky X " which is fun to use on a Computer. I am debating on attaching the 5 X 24 Finders Scope & Bracket onto my Celestron First Scope. I feel you would not need to attach it because once you put it on a tray table or any sturdy surface you can Pan the Telescope up and down and then Left and Right. All in all this is a great telescope and you canhave fun and learn all about Astronomy.

A Great Telescope

I have purchased the Celestron First Scope Model # 21024 at Celestron and I called them up to order the telescope. The telescope is a mighty one and I feel it's a great telescope to learn all about Astronomy. It comes with two Eyepieces an H 20 mm and an SR 4 mm Eyepiece. You can even print out the handy Celestron First Scope Instruction Manual for the Celestron First Scope Model # 21024. It's easy set up and design is a Snap you don't need any tools you just insert any lens. and you can use the Celestron First Scope on a Picnic table, a tray table even your car hood or the back of your car or any hard study surface. Also I have ordered the Celestron First Scope Accessory Kit. I have found an old Finders Scope and I attached it to the telescope. It's a great telescope and as a beginner I feel that this telescope will be a great item to learn all about Astronomy. I believe that this telescope will be a great item now and in the future. Also the telescope is wonderful and easy to use. By using the Celestron First Scope and the Celestron Finders Scope just select and object, aim, point and then focus.
