    Default Just arrived: 150mm f/5 refractor



    This evening my 150mm Skytraveller arrived. I spent the evening re-arranging accessoires. And I made a finder on it.
    The evening was not clear, I had trouble finding the Summer triangle in the misty skies. Nevertheless it showed various DSO's.
    I like him already..

    I'll make a report in the morning.

    As promised, my report of the first light.

    At arrival in the original box the 6 inch was in a perfect condition. No scratschmarks, no stains, no dust inside. The first owner used it as a photographic instrument and had mounted a far better focusser than the original. I had seen his pictures with this instrument and knew nothing could be wrong optically either.It seemed a bit lighter than my fully equipped 4.7 inch. Soon I found out that was not the case once fully equipped.

    It came with two Vixen dovetails, one of which was used as a handlebar and photographic platform. The gap between handlebar and tube was rather narrow so I enlarged it by adding some extra nuts. Since the new TS-focusser had no finder-shoe-holder, I used the handlebar to act like a good base for that. Drilling and tapping an already home-made existing hole took care of that.

    Time for mounting. Balancing showed me that I had to move one counterweight a bit outside. I had to shove the tube down in the cradle and mount the middle of the dovetail a bit off the middle. While looking at the zenit I want to sit down on a small stool, still I have to bend a lot, but luckily I won't have to sit on the floor. The picture above shows the balanced telescope.

    I aligned the finder on some trees far away, it was not really dark yet and in the meantime found out I could not reach sharp focus. Since It had been designed for use with a 2" mirror, focus was far more further away than I could reach with the 1.25" Zeiss prism. A comparison of its behavior with a mirror will follow in near future:-)) Luckily I still had a 2" extension tube from previous experiments. It fitted of course and focussing problems were over.


    Time to check if the telescope sits on the mount the same way as my 120mm refractor does. It does. Vega was still in the memory and after entering it showed up in the 30mm Eudiascopic eyepiece. I checked collimation with my Pentax XO 2.58, at 300X and found out it was all right. The startest on Altair did not reveal major problems. I was a bit surprised about the small Airydisc, until I remembered that an F5 system produces smaller Airydiscs then a F7.5 Nice promise for double stars. A bit of axial coma in the order of 1/10 wave, but nothing to be alarmed, quite normal for its budget range. Spherical aberration seems to be in the order of 1/5 to 1/6 wave. According to the program Aberrator it should even be better. I did not check on axial astigmatisme, but as I did not detect it in the first place, it should be low-leveled. This refractor meets the 0.8 Strehl limit effortlessly.

    Since it was a very misty night, the Summer-triangle was the only naked eye-object, I wondered how much this telescope should reveal on some DSO's I had in mind. I put in a UHC filter and went for M27. I was not surprised to see it quite clearly and I could detect its form. M57 was even more clear and sharply defined. I nodded, this is how I wanted it to be. M71 ( without the UHC) was visible, but without the well known little stars. M15 showed individual stars in its periphery. I wondered how M13 would look like. Surprisingly well, as if I looked down a ( dark) sugarpot.

    The one issue almost every review keeps dragging on about, the CA ( as if there is nothing else to remark about this telescope), is no issue for me. Surely I saw a blue halo around Wega an Altair, but I think it was a moderate one. I was not impressed. Maybe due to the use of a prism instead of a mirror, but I am gonna find out. Saturn was all right. Jupiter showed some cloudbelts and zones, the GRS ( ever so clear) and was certainly not what I am used to in my 120mm Apo. Well, it is not made for Jupiter, that's for sure. But it shows me 99% of all other objects with a big smile.

    I could have been going on like that for several hours, despite the very bad circumstances. But the weather worsened , I saw lightning on the horizon and heard rumbling. So I called it the day and went in. Satisfied. Can't wait for a real transparent night.

    Hello John,

    I have sent you my congratulations already in advance, now enjoying your first light report.
    The performance of this achro as you have found, sounds very close to my assesment of basically the same scope.
    With the right chosen eyepieces (and other accessories) it is a great performer, and you will enjoy it very much.

    Best,

    Thanks to all for you kind remarks.
    Like you I am looking forward to my first real transparant night out with this telescope.
    As promised I will give a report on the behavior of this instrument with a Zeiss-prism and a BBHS mirror diagonal.

    Sounds great John!

    I am sure you will continue to love the scope. I was blown away by mine (Celestron badged) when I took it to a really dark sky. One view that stuck out for me was of Eta Carina. I know this is not in your sky, but it is a bright emission nebula (the wide-field nebulosity gives M42 a very big run for its money!): and the "homunculus" surrounding the star itself is becoming easier to resolve. When I checked this at 150x in the scope I was amazed that I could see it as a red colour: something I hadn't noticed before, even in an 18" dob. I assume this is because the transmission of the doublet is skewed towards the red (JG: correct me if I am wrong!), but in any case it was quite a sight: I likened it to two small reddish cauliflowers either side of the star (just like the Hubble images! sort of...).

    I will be interested to see if you have a similar experience with any of your northern emission nebulae.

    I am tempted for future dark-sky camps to take just the 150 F5 and my TSA102, and not bother with my 12" dob: the views through the refractor are that good! (...and besides, there is always someone nearby with a 18" dob that I can have a look through!).

    Have fun!
