What can you see with a 4.5″ telescope? – Moon

Today I saw the moon and it was awesome. In a way this is the first light for my telescope even though it is second hand. I could clearly see the mountains, impact craters, lava filled craters, craters with a small peak right in the middle, the dark colored flat regions on the moon, craters within a crater, so on and so forth ……………… 🙂

When I used the 25mm (36X with a Meade 4400) eyepiece, the moon filled the field of view while the 12.5mm (73X with a Meade 4400) eyepiece allowed me to view about half of the moon and more details. The 4mm (228X with a Meade 4400) eyepiece showed only a small fraction of the surface but it enabled me to see numerous surface features. However since I was at a high magnification, the moon moved while I was viewing it and in few seconds I had to realign my telescope. After a while this became irritating and I switched back to 12.5mm eyepiece.

My 3X Barlow lens was not of much use since any magnification at or above 200X causes the moon to quickly move out of view (I do not have tracking mount).

Pics are coming sooonnnnnnnn ………… (if I can manage to aim my DSLR into the eyepiece without smashing my camera’s lens!!)

PS: Viewing from backyard in the light polluted city of Phoenix, AZ, USA

Pics are not at all good since I was pointing my DSLR on the eyepiece and contorting my body in all possible ways to align with the optical axis, a.k.a. “afocal coupling“. This is pretty much the size that you will get to see with a 12.5mm (73X with a Meade 4400) but it will be much more clear and sharp.
