  1. This is just a log of my observations last night from my balcony. It has quite a restricted view due to it being recessed so the floor above me gets in the way. It faces south-east-east and I have around 80-90 degrees of azimuth view. If you’re prepared to watch the constellations appear it is ok and put up with the streetlights on the paths it’s ok. I have places nearby where I can set up to get a better view of the sky but it’s summers and I could hear some people having a party in the park. I thought I’d leave them to it as it will be cold in the winter and the night time park will hopefully be empty! I was using my 102mm Mak on an eq2. I’d been hoping to have another attempt at the Ring Nebula in Lyra but the floor above me was getting in the way. I should have got out a bit sooner – with it not really getting dark enough until ~2330 and it going out of view for my viewing spot I’ve only got a short window of opportunity for this target at the moment. So I settled for Albireo. This was the first time I’d gone for this double in Cygnus and it’s a lovely sight. A warm orange spot with it’s hot blue partner. It’s not as hard to split as the Double double (which isn’t hard either but it’s the only double I’ve seen so far which I know the name of J ). I then decided to try and find M31 which isn’t visible to the naked eye for my location but the Andromeda constellation was easy to make out by following along from the belly of Pegasus. M31 proved a hard target to find at first. I’d initially started to use the two stars I could see that formed the waist of Andromeda which seemed from Stellarium could be used as a pointer up towards M31 but no amount of wriggling the scope whilst moving up worked so I consulted Stellarium again. Although I can’t see Polaris to polar align I can get a good enough polar alignment by pointing the polar axis north and the latitude for my location. So I could see that if I went up to the centre of the cross of Cygnus (Sadr), moved my declination up a couple of degrees and then scanned back with RA I might hit M31. Whilst getting my up and down mixed up on my declination axis, I happened across a star cluster which took me by surprise a bit. It seemed that I’d mistakenly found M29 after checking with Stellarium. After M29 I decided to put the scope in the right position I’d intended to scan back to M31 from Sadr in Cygnus. This approach didn’t help either! Back to the drawing board. I used the star near the head of Andromeda as a guide next and moved my declination up whilst giving the scope a wiggle and M31 came in to view. In my little Mak it was only the smudge of the centre but I was surprised how big the smudge was. I was expecting the core to appear smaller but I would estimate that I could see around 0.2 to 0.3 of a degree (I was using a 20mm Erfle which gives me ~1 degree in my scope). Having found M31 I was starting to notice more stars in the sky now. I could see the two brightest stars of Aries and the Triangulum so decided to attempt M33. I spent ages trying to find this but couldn’t do it. After doing some research today though it seems that M33 surface brightness is very low so maybe my scope is too small and I have to be a bit more patient when scanning the sky. The same research threw up the obvious question as to why I didn’t see M32. I should have been able to see it with M31 however I probably mistook it for a star. Now I know how to get M31 I’ll look out for it next time. My next target for the night was M34 as I felt this would be easy to find by scanning in RA from Almaak in Andromeda. Whilst lining up on Almaak I noticed this was double with a small companion. This was a double that I was going to put a name to! I’d seen a few without naming them but it’s so easy to find in Stellarium that I had no excuse although I was a bit thrown out when Stellarium didn’t show it as a double in ocular view. Some wiki research today confirmed this though and Almaak’s companion is a double itself but they are seperated by less than an arc second so not sure if I have the resolving power to try this when I go back to it. I found M34 after looking at the Almaak double. It wasn’t hard to find this time. Whilst the open clusters are nice and I like the way they jump out at you as you’re scanning across I must admit I preferred viewing M13 when I first found it. Even though I couldn’t really resolve stars in M13 I just found it a more exciting target. I suppose as it seems like a galaxy within a galaxy. I could now see Jupiter rising through some trees in the distance so tried to get the double cluster but I was just restricted by the floor above again and I could only see the southern half of Cassiopeia so I went to M45 which I could just see as a smudge 20 degrees or so above the horizon. There’s no way I can get all of the Pleiades in my FOV but it was fun scanning around it and all the other stars appear within it. Finally Jupiter had cleared the trees so I concentrated on this now. The seeing was quite bad, the transparency was getting worse (a haze was starting to develop around the planet) and Jupiter was still quite low.I found that my 10mm plossl was giving me a bit too much magnification and I was better of using my 15mm or my 20mm erfle with the barlow cap in the end to give ~100x magnification. Detail was hard to make out though and I was restricted to seeing 2 bands of brick colour on against the cream background. Unfortunately the moons were nicely spread out this time; I’d been hoping for a repeat of when I watched one of the rise from behind Jupiter a week ago. I’m looking forward to when Jupiter starts rising earlier in the autumn so I can view it higher in the sky to beat the seeing before the Sun rises. So that was last night on my balcony waiting for the earth to spin. Next week looks good my way for weather so hopefully I can repeat it soon.

    Quick Andromeda Galaxy

    I got a new telescope a few weeks ago, a Skywatcher 150P-DS, and I've just had it out yesterday, as the danish summer has been absolutely horrendous.. But it's only just now, that the astro-dark nights are returning again anyway. And what better easy target to test it out on, than the Andromeda Galaxy? But there were only like a total of 2-3 cloudless hours yesterday, so I only managed to get 26.5 minutes of 30 second subs, as I was also observing and getting used to the new scope. The focus is a slight bit off, as I've still to make a bahtinov mask that fits this one, and I can see that I really do need to get my hands on a coma-corrector. I am currently looking at the Explore Scientific HR Coma Corrector. People have recommended the Baader Mark-III MPCC, but some have also complained about it introducing spherical aberration? Other than those issues, I am very pleased with the quality of this scope and how easy it was to produce these images. Just the fact that the DSLR can actually reach prime-focus, without the use of a barlow-lens or something similar, is just a big plus compared to what I've had to deal with! I'll give it some longer tests when the next dark, cloudless nights hits, which might be a while! The field of view of the 150P-DS is a bit too small for something like M32, so I might make a 2-pane mosaic sometime.
