START : 22:03 WEATHER : 17 DEG C - ??% Humidity
FINISH : 00:42 WEATHER : 13 DEG C - ??% Humidity
UPDATE : Used PemPro tonight to align the mount. Adjusted both axis. The adjustment is nowhere near as easy, fine or accurate as the ME. It's shocking how much you need to pay to get a decent mount. I have done the best I can and will now leave and try and track another night. I can't wait to get the AstroPhysics mount!

START : 22:23 WEATHER : 9 DEG C - ??% Humidity
FINISH : 23:42 WEATHER : 5 DEG C - ??% Humidity
UPDATE : So I still need to polar align the mount using PEMPro. for now I have attached the Telrad to the scope to help align at the start of the evening. I also still need to cook the descant. I will take that in tonight. I have performed pinpoint and synced and all is well. Noting that EQMOD does not let me slew if it is pointing at the trees as laid out by my personal horizon within the sky. This is a good safety feature. To get around this as the parked position is within this horizon boundary I manually slew the scope above it. After that I can point within TheSky and then slew.

I noticed tonight that 1 min is fine without guiding however 5 mins caused huge star trails. I must get this mount aligned. For now that's another few things this evening completed so I will now poack up and take the descant in. Then once aligned maybe I can image the faint Sharpless 73 object.

Date - 2nd May
UPDATE : So the first update for some time, I have tried to go out recently but failed to get anything working including being able to update this Journal. Goodness knows why! Anyway since February and now I have purchased and installed the new NEQ6 mount (temporary but maybe for some time!) I have focused the camera, fitted the new focal reducer/flatner from Williams Optics. I have also fitted the Lakeside motor focus and got that working.

What I now need to do (when it stops raining, as it has rained for nearly 3 weeks!) is to polar align the mount probably using drift alignment with PEMPro. Tonight I failed to get the Pinpoint working however I have had working the last time I came out. Since I did not record in my Journal how O got this working I now clearly cannot remember. I think, indeed as I left the dome, that it may have been the Maxim sw not connecting to the Sky correctly.  I'll check the next time I go out.

Date : 9th February
UPDATE : As you can tell I have not been very active in the dome as of late. A mixture of work (a necessary task) and the more fun outward bound Astronomy with my society. I must say it has been a busy start to the year with Stargazing live events, the start of our Basingstoke Astronomical Society meetings, committee, practical and main. I have also been into my local Junior school to continue teaching Astronomy to the children and then back for a very successful clear evening viewing with some 50+ children. Fantastic! So now you know why I have not been in the dome. 

I have also been dismantling the Paramount ME mount that I have now sold to Chris from Scotland. I hope he has as many good evenings with it as have I. I am in the low point of now saving for my new setup on my wish list of an AP3600 and CDK20 OTA with a wide field camera. Whilst that is more than likely still some years away I will be buying a Sky-Watcher NEQ6 mount from Astrofest tomorrow and mounting my Williams Optics back on. Over the coming months and years (until I can afford my dream setup) I will be taking wide field images and learning to process them on Pixinsight. To start my friend Tim Powell has processed the raw data I gave him for SH171 and the image is below. I hope to learn to process this well soon. It is a spectacular image from my narrow band data. I'll put more info up about it on it's own page soon.

START : 18:45 WEATHER : 6 DEG C - 58% Humidity
FINISH : 19:59 WEATHER : 5 DEG C - 58% Humidity
UPDATE : Finished the Blue data for the Californian Nebula tonight. I wanted to take a few frames to practice on PixInsight processing LRGB before I get into processing my narrowband image of SH 171.

TARGET : 

NGC 1499 - Californian Nebula - 4 x 5min Blue (WO)

DATE : 2nd January 2012
START : 18:23 WEATHER : 4 DEG C - 64% Humidity
FINISH : 21:03 WEATHER : n DEG C - nn% Humidity
UPDATE : So the second day of the year and the first time out to image. I decided to do a quick imaging run of the Californian Nebula NGC 1499 in LRGB. I got 4 frames in Luminance, 4 in Red and 4 in Blue however the clouds rolled in before I could take Green. I shall gather that during the next clear night hopefully tomorrow.

TARGET : 

NGC 1499 - Californian Nebula - 4 x 5min (L) 4 x 5min (R), 4 x 5min (G) (WO)
