Well just a simple sketch. It probably just convey only 70-80% of what I saw. Observing and sketching will enable one to see more details. :) Anyway there are really beautiful and colorful sketches done by other people… looks real artistic and accurate.. I don't think I can ever reach that level. Haa.

It has been close to 1 year since I brought out my 12.5" telescope to study Jupiter; as Jupiter rise very 'early' for months and I cannot wake up at 4 or 5am to observe it… Now Jupiter is rising earlier in the evening and at 11 plus PM it is high in the sky, prime for detailed observation of th...

Think there are 4 obsession telescopes in Singapore. The smartphone with its small lens can match the exit pupil of a large aperture telescope. This image is at around 100x magnification and with a ultra wide angle nagler eyepiece is able to cover more than a full moon. If I were to use 100x with sm...

Just took this picture through my 12.5" Obsession dob + paracorr + 17mm Nagler Eyepiece. The moon just fills up the width of the iPhone5 chip. I got a iPhone afocal adapter and was able to centre the phone quite well to the eyepiece. :) Attached is the link to the raw single image. http://posti...

Hi Gavin, Jupiter is pretty low that is why you won't be able to use higher power. Typically there is at least a difference of 100x useable magnification of Jupiter from low to high (close to Zenith). For my 12.5" my most used eyepiece is 5mm Pentax XO at 320x. It gives a pleasing 1mm exit pupi...

Cool. Great to see Obby's bro working fine!

Hi, For f/5, using barlowed laser collimation is sufficient to get very good results. Note that all lasers have some form of misalignment and also the 1.25"-2" adapter also have its own errors which will contribute in some way. However, using barlowed laser collimation technique for the pr...

Ha actually it started out I wanted to show my 20 month old daughter the moon. Was afraid she cannot view through the eyepiece so thought of using the iPad large screen to show her. Turned out she manged to view the 'big moon' when I carried her to the eyepiece. The iPad did manage to capture the mo...

Attached are two images I took by handholding my iPad looking through the eyepiece of my 12.5" telescope. They are unprocessed. Turns out not bad for such crude way of taking images. Considering that the iPad camera is pretty lousy and far inferior to a iPhone5 camera. 12.5" Obsession tele...

Yes thankfully my mom, wife and daughter were safe in the fire and were rescued by the firemen. All the things are back to what it was.
