Post by Mike Q »


The skies cleared up late afternoon and the forecast was for clear skies. I decided to do a big and small night. The AT 102 EDL and its iOptron mount and the XX16G were rolled out. I picked a spot where I could get on Orion one last time. Alignments were done and the first target was picked.

NGC 2362, Tau Canis. If there is a prettier cluster overall I am not sure what it would be. In the 4 inch it looks hazy in the center, in the 16 all the stars are very bright and the two companion stars show up nicely. There was still a bit of haze or nebulocity in the center, but it was stunning none the less.

Off to M42. Five stars in the trap with the 102 and 9 with the 16. Not to bad given Orions position. I am still amazed of the amount of texture the 16 inch delivers with 9mm/100 degree eyepiece.

NGC 1990 was looking good in the 4 inch with plenty of nebulocity showing. In the 16 the blue white central star almost blew away the nebula, but the beauty of the pin point star was undeniable.

I was bound and determined to get the flame, but it didn't happen as I wax distracted by the Horsehead. So I traded the flame for the Horsehead and called it good.

The Hercules Cluster was up and it showed well in the 102 with a 6.7mm, in the 16 a 9mm gave a view that won't be forgotten anytime soon. The ES 9/100 might just be my new favorite globular eyepiece.

Numerous galaxies were observed including M84 and 86, M101, M51, M104 and wrapped up the night with M81 and 82. As expected they revealed themselves smudges in the 4 inch, in the 16 structure could be seen in all of them.

It was well past midnight and teardown was going to take a bit so I packed it in and finally rolled into bed around 0130. It was a great night that I am going to gladly pay for all day today.

A couple of takeaways from last night. The iOptron mount was aligned using its GPS alignment and the Orion using a 2 star alignment. I thought it was interesting that when the slewing was done they both were looking at the same point, I had really expected them to be a bit different, but I am not complaining. The frac gave its usual pin point stars, but the big 16 was perfectly collimated was delivering pin point stars as well. I also noticed that the defraction spikes of the big reflector were almost imperceptible. They were there, but very small. You couldn't ask for better iamge.

Neither of the two times i have seen it had i used filters. The first time i was using my ten inch and the skies were very good. Now bare in mind i didnt "see", i could see a piece of it and a break in the nebula behind it. Last night was also unfiltered but despite Orion being in a less then perfect position, aperature got the job done. I did put a h beta in so the wife could see it and it did bring it up more so she could see it easier.

I know what you mean Mike. Visually it is nothing like in photos. Still, you have good skies if you manage to observe it without filters.

Last nights skies were pretty good. Clear and stable, it was the second or third time this year I have been able to use 200x. When I saw the Horseheads the last time, Orion was almost at Apex and the skies were even better. In my part of Ohio 200x is "high power". In the last two years I have been to 300x a couple of times and 400x once.
