A Clear Night...Finally

It has been a very cloudy month in the Pacific Northwest.  However, the night of March 30/31 was a cold, clear night.  A friend of mine uses Megrez to determine how well the seeing is and for me, the 3.3 magnitude star stood out fairly easily in my urban sky.

I decided I would tackle a couple of galaxies...M101 and M51...and took out the ETX80. 

After aligning the scope, I punched M51 into the Audiostar Handbox and watched the scope slew towards the area of M51.  When the scope finished slewing, I looked into the eyepiece and at first saw only a couple of stars.  I was using a 32mm Plossl and after a few moments, noticed a little fuzzball about midway between west side of the view and center.  I had to move the scope a little to center the galaxy in the view of the eyepiece.  I don't think I will ever hit the correct manual slew button on the first attempt...hehe.

I was pleased the GOTO found the galaxy as I wasn't exactly perfect in aligning the scope.  Through the 32mm, M51 looked a lot like a fuzzy comet.  It being rather small in the view, so I swapped out the 32 for the 13mm. 

Again M51 was to the west of center and a slight adjustment (still didn't hit the correct directional button right away) put it more or less centralized.  With the 13mm, I could see an oval shape to the fuzzball, but no other detail.  I was rather disappointed in that.  I thought The Whirlpool Galaxy would show some arms.  I switched out the 13mm for the 6mm, but I lost the contrast with the 6mm and went back to the 13mm.  

With the 6mm, there was a star of about 8 mag to the east of M51.  With the 13mm, I could see one other star north-northeast of M51.  It also appeared at about 8 mag.  All attempts at using averted vision to see some detail didn't bring out much, although I thought for a moment or two I was seeing some banding of arms.  It would come for a split second, then disappear.

Being the "Old Fart" that I am, my fingers were beginning to go numb in the 28 degree temperature, so I decided M101 could wait for another day.  After seeing what I saw of M51, I wonder what M101 will show.

Maybe I'll use the ETX 125 on it.

Feb. 10 and 11, 2017

It's a milestone day!  My first true astro post...

Feb. 10 brought a penumbral lunar eclipse at moonrise.  Since my eastern horizon is rather blocked by tall trees, I waited until I could see the moon well enough to see if the Earth's shadow was visible. Unfortunately, I couldn't see any chance in lunar brightness from the time I began watching and the time the eclipse was predicted to end, which was around 6:45 pm.  But in my defense, I have old eyes and the moon was very bright.

Several hours later, I grabbed the binoculars and went outside to look for Comet 45P/Honda-Mrkos-Pajdušáková.  I had a good idea of where the comet would reside in Hercules and went to the south side of a storage shed on the property where I live.  I tucked myself into the slim shadow of the building and scanned the area below the keystone.  I didn't see 45P, nor did I see anything which looked greenish to my eye.

Once again, the bright moon interfered with what I wanted to do.

I did briefly consider bringing out the camera and tripod, but it would have been difficult to set the tripod in a spot I could frame the image based on several factors...the moonlight, the snow still on the ground and the proximity of the building to about the only place I could setup.

Snow depth is falling finally, and should open my regular observing area soon.  I don't have great sky views here, but I do have a north-northwest to east view of the night sky, and a sliver of a southern sky.  But I do have a nice view above me.

Not sure when my next update will occur, but I do want to give the ETX-125 a maiden voyage.  I spent a few hours this afternoon mating my Lenovo laptop with both the Meade scopes.  I had to order another USB-to-Serial adapter and it arrived in today's mail.  After loading the drivers for the adapter, I made all the connections and was able to control the scopes from the computer on most of the astro programs I have on the computer.  I didn't test the setup on all of them, as I will only be using the Meade Autostar Suite program and C2A to control the scopes.

Well, that is all for today.  Clear skies and no moon, y'all!
