Stargazing 2019.007.1 – Trying for Mercury and Mars with a Celestron NexStar 4SE

My son’s grandparents have a cottage up in the Kawarthas, and it is relatively dark skies. From the dock area, you have a pretty good view of the sky to the South and West, whereas North and East are blocked by trees. We took our son up for a week, and just took his scope rather than his and mine (mostly due to space limitations in the car). He didn’t want to keep the scope to try on his own through the week, so we were leaving him but bringing the scope back with us. Which meant only one night to try viewing, July 6th.

The Clear Sky Chart was showing great clear skies, but the clouds didn’t get the memo. We set up around 8:00 p.m., and by the time we were set up, the moon was completely covered as was most of the Western sky with dark clouds. It opened up about 10 degrees above the horizon, and we got a great sunset, but that wasn’t my goal. I had updates from the sky trackers that Mercury and Mars were trailing the sun, and it was possible to see them as the sun dipped below the horizon. Maybe they were there, I have no idea.… Read the rest

Stargazing 2019.006.1 – Testing a Celestron NexStar 4SE

My son enjoys looking through my telescope and has been wanting his own scope for awhile. So we went through a number of designs to see what he would like, with me trying VERY hard not to lead him to any specific conclusions about his own preferences in design. He has a few extra mobility challenges over me, and he ended up going for the smaller version of my Celestron NexStar 8SE — he chose the 4SE.

It comes with a couple of advantages and one disadvantage over mine. For the disadvantage first, it’s simply smaller. A smaller light bucket gathers less light, so things won’t be as bright for distant objects. On the advantage side, the 4SE is a slightly different design (Maksutov-Cassegrain design) which will make for crisper images; it comes with a built-in wedge (if he wants to try equatorial tracking for astrophotography); it is smaller and much more portable; it has a sturdier tripod vis-a-vis the overall weight (his scope is light for his tripod, as it is also designed to hold the 5SE model which is heavier whereas my 8SE is on the high-end of the load options for the tripod it comes with); and his alignment worked perfectly right out of the box.… Read the rest
