On Saturday night I was able to make time to do some imaging. I decided to image a section of the Veil Nebula. I ran a LRGB session of the Veil Nebula which finished early in the night so I thought I would try a Ha image. I have never imaged through the Ha filter and was interested to see my test results. Since this would be a long exposure it would be a good test of my auto guiding system as well. The LRGB run was 3 images at 600 sec images for each filter with guiding on a 9.5 mag star. My guide exposures were between.10 and .35 sec. The Ha filter required 2 sec guiding exposures meaning the AO would run at .5 Hz, I was interested to see how that all worked. The Ha image was to be a 1500 sec exposure so my system would have to guide well for 25 mins. The image above is the result. This is 1 exposure at 1500 sec Ha with an auto dark, no flat field. The only post processing was de-blomming in DL and levels adjustment in PS CS5. I was pleased with the resultant image and the guiding of my system, good structure in the nebula and nice round stars. PS- the LRGB images has not been processed yet. Enjoy and keep the telescopes pointed up.
News– Well it has been awhile since I have written anything so thought I would share with you what I have been up to this winter here at Windy Hills Observatory. The weather this year was an improvement over last years cloudy winter weather so I have been able to image several targets, the Horsehead Nebula, M33 and M1. I just completed processing them and will share the images later in this post. I am still fine tuning the remote operation of my dome/scope and have made progress. I added a Optec TCF-S focuser and a Pyxis 3-inch rotator. This allows me to rotate the camera to place a good guide star on the guider chip, the rotator is controlled by software and can be placed at any angle. The focuser is controlled by CCDsoft camera control software which allows for auto-focusing. The dome follows the scope by using Dome Works Dome TraK. I presently use TheSky, CCD AutoPilot 4 and CCDsoft with PinPoint to control the whole setup. My goal is to automate the data capture of targets and to be able to image several targets in one night with out being at the scope.
Images – Below are several new images that I have taken this winter.

First Impressions – I purchased TheSky X Professional as an upgrade to TheSky 6 late last fall but had not integrated it into my work-flow until last week. I also purchased the add-on camera module and Tpoint module. I thought I would share my first impressions of the software. TheSky X has all the features and functions of TheSky 6, some of the names have been changed and the icons relocated but basically the program functions are the same. I did play with the software a lot before I put it on line in the dome. The switch was painless, I set the COM Port, selected the telescope type from a pick list and established a link with the LX200R with no problems. The new real time graphics are GREAT! The tool bars and windows are customizable you can add and delete tools, buttons and windows to fit how you operate. The windows and tool bars can be moved about and placed where you want them. The camera add-on is basic at this time with few camera setting available. Software Bisque has stated that they intent to increase the camera functions later. I would imagine that since Software Bisque owns CCDsoft many of CCDsofts functions will be added to TheSky x. If this happens this will be nice since you will be able to image from one software package. One thing that was easier in X to me anyway was setting the slew limits for my set up. I now feel comfortable that my scope will not go pasted the limits with out me telling it to do so. One of the reasons I upgraded was that I wanted to improve my telescope pointing. I looked into Tpoint. Tpoint is offered as a package that will work with TheSky 6 but with TheSky X it works in the program. If I purchased Tpoint for TheSky 6 I would have to purchase an upgrade for Tpoint TheSky X version later if I upgrade to X so I decided that I would just start with the X version. This was not a mistake as I have improved the LX200R from a 150 arcsec error to 27 arcsec. This was done with Tpoint in less than 45 min. Tpoint and TheSky X took 50 images and plate solved them, I then pushed the Super Model Button and was done. Before Tpoint I would slew to my target center a star and sync on the star. CCD AutoPilot would then use Pinpoint to try to center the target usually with in 50 arcsec. The best I would get was about 20 arcsec. I can now slew to any part of the sky and be with in 27 arcsec of the target center, CCDAP4 with PinPoint then corrects and moves the scope to with in 5 arcsec. The upgrade was worth it to me as the improved pointing of my Meade LX200R production mount has made my goal of automation easier. Clear skies and keep the scope pointed up.
