I've been trying to image a couple of galaxies per night, one pre and one post flip. On early Saturday morning at 1:30am I changed over to M82, and acquired 63 x 3 mins subs, OSC, totalling 3 hours and 9 minutes of data.
Camera: ZWO 2600MC at -10 deg C, gain 100, offset 50
Telescope: Skywatcher 250PX (blue tube), 1200mm F4.7
Mount: Mesu e200
Guiding: ZWO OAGv2, 290MM, PHD2
Software: APT for capture, APP and PS for processing
I havent really had a chance to get much use out of this camera since I bought it in December, and I havent processed many OSC images before. I've a bit of work to do, but still very happy with the quality of the data for just 3 hours of integration time. I would like to add some Ha to this, but purposely didnt bother during the recent clear spell, as it was moonless nights and I gathered some broadband data on other targets instead.
Good evening everyone.
I am seriously considering purchasing a Mesu mount for my ROR observatory. This will be a set up and forget mount as many of you have alluded too. I have spent quite a substantial amount of time pondering over in my mind the many telescope combinations and what I enjoy looking at and would like to photograph on the astronomy tools website.
So with the mount, I would pair an esprit 120 with a suitable wide field scope of around the 60 to 70 range and around 350 to 450mm focal length. The sharpstar 61 seems to fit the bill and with the option to fit a reducer, the scope can go even wider. The esprit is a well loved instrument but the Sharpstar scopes are fairly new so I would welcome any feedback from new owners.
The Mesu, what can I say? From pouring over various owners posts and threads these past 12 months and seeing the impact on ‘relatively’ trouble free use, it is undeniably worthy of consideration. My only concern is the sitech control system and the numerous ‘niggles’ users have encountered over the years on this forum. Another consideration is the Gemini EFric but for the price and a little bit more money, the Mesu makes a very good case for itself. Do I need 50kg carrying capacity, probably not. Possibly like the majority of current owners. And lastly the Ogem (now the Trident), it’s difficult birth and delays on production and delivery have made me a little wary to be fair.
The final piece of the jigsaw is the camera. Not too sure but the one shot colours are preferred due to time and the different objects I want to view / image. Thinking along the lines of the Atik Horizon II.
The star of the show though is clearly the mount in the equipment list. Just been speaking to Bernard at MA and he has one left in stock (pre Brexit stock) and I am sorely tempted. I don’t have the funds at the moment I’m about 2 months away from having the money, do I - get a low rate loan and pay it off when the money arrives or pass it up and wait until the money is here and the mount is likely sold and wait for the next one (post Brexit). Not sure 🤔
Update - deposit now paid!
As always your thoughts are welcome.
Monday 5th Oct: un-boxing & 1st View
During the day outside I unboxed a Nexstar 8SE (25mm EP) and did a course alignment of the red dot finder. I'm using a TalentCell power bank & that worked well.
I planned to leave the scope outside but rain arrived.
In the evening I attempted to setup the scope in the dark. I misplaced the camping and the OTA fell into the luckily soft lawn. So that's the metal Shell christened 🤔
I did get to see a glorious moon surface. More detail than from my 80EQ firstscope.
Evening 2: Tuesday 6th
Mars was tonight's planned view.
I didn't get on with a skylight so did a solar align on Mars.
Compared to my old scope I've made Mars a brighter White disc with some greyed areas. (25mm & zoom EP)
The worst thing was mars drifted and when I tried Goto the scope went further away. Looking at my setup I found North America rather than U.K. 🤔
Eve 3 Friday 9th
Last night i.used a GPS to add my garden's Long & Lat as well as a time entry using seconds with my iPhone as the visual time aid.
I failed again at the 1st skyalign. The solar planet align was used again.
Mars was the target and my viewing.
It was a bright disc again but with maybe more obvious slightly darker areas.
Mars drifted again even though the scope's Motors could be heard.
I retired a 3 bright object alignment and this time the Nexstar was happy.
I could choose over planets and Goto back to Mars. It wasn't central in the eyepiece but OK
How similar to novice backyard astronomers is my early experience?
I am surprised at the drift in a goto.but hope.that I just need to be better at Skyalign.
The focus setup looks good as Mars out of focus is two perfect circles looking like a doughnut. I didn't observe how an OOF star looked.
****** Bottom line, when the scope fell out of the clamp that 1st day, have I damaged it's function and not just good looks? ******
****** Is drift a sign of inaccurate alignment? *********
ps Not mentioned is my garden is poor for light pollution and with the old scope it became just viewing the moon & Sun I relied on for interest.
Mars did look ok ~2000 we saw a polar cap with the old scope.
Thanks for reading.
I am upgrading my mount for my observatory. I will be doing AP primarily but to be honest, I also enjoy some visual. I need about 30-40kg capacity. I had my heart set on the ridiculously expensive 10 Micron 2000 (coming in a about 12k when you figure all the extras needed). Something seemed wrong about that price....!
I now have an opportunity to get a Mesu 200 Mark II. The mounts engineering looks unquestionable and I have yet to hear anything bad said about these mounts. The price is also very attractive compared to the 10 Micron. My issue is the control. I’m going to be honest - the controller looks rudimentary (and with no screen, controlling from the computer for visual may be annoying). I have no knowledge of Sidereal technology at all. I am very close to purchasing this mount but I would like some feedback on user experience regarding the software and control of the mount. I note the new version will have the Scitech I controller but I thought (perhaps incorrectly that the older version has the II controller). I am not sure if this is significant or not.
Opinions and feedback greatly appreciated.
