There are several extremely active threads running on CN about the LX850 and about Meade’s future and all of the mistakes that drove Meade to the edge. One frequently-reported mistake is that Meade didn’t offer the kind of telescope the poster wants, as though the poster’s  preferences alone drive the market. In many cases, the product Meade “failed to deliver” was actually a good seller for a decade or more; in others, it was tried and no market was found. Either way, it appears that the poster is just unfamiliar with Meade’s product history and is merely making stuff up to complain about. The truth is that Meade made real mistakes, most notably the premature RCX400 and LX800 releases – but those are old news. They contributed to Meade’s current problems, but they aren’t relevant to discussions of the current product line.

 

In the active threads, one might wish that the majority of posts were from folks with experience with the new products – but this is not the case. Most of the posts come from a few people who haven’t used the gear but  just can’t stop repeating their rants and who apparently don’t read posts from folks with more knowledge of the products. Between the attacks and the fact that posts apparently aren’t read anyway there has been a chilling effect; those with the greatest knowledge of the relevant products are posting less and less. I certainly don’t feel like entering the fray until I have something specific to report or a new image to share.

 

The funniest bit is that one of the most active of the Meade bashers is actually a dealer for several mount manufacturers who compete with Meade! This kind of thing is one of the primary reasons for the restriction in CN’s Terms of Service, which forbid a vendor from “commenting, directly or indirectly, on competing products”. I believe that he has simply worn the moderators down by posting all day, every day (no other vendor does this on CN). If the mods tried to enforce the rules on this guy, they’d have to quit their day jobs.

 

I did see my name mentioned today; someone commented that I seemed to be pleased with my LX850, but that it wasn’t outperforming my previous mount. If one doesn’t know what that mount was, it might seem like a disappointing result. As my previous mount was a Takahashi NJP, that would be a misunderstanding. I’m certain that Meade never hoped that the LX850 would outperform an NJP – but in one sense it actually does! Out of the box, it does a better job than the NJP did out of the box. The NJP required additional guiding hardware (OAG, guide camera) at the focal length I’m using. If I thought I could easily find that post again out of the pages and pages of noise, I’d probably step in to clarify that.

I see that it’s been over a month since my last post. Weather, time, and health have kept me out of the observatory so there are no new imaging sessions on which to report. Here’s what I know since then:

I mentioned a while back that I seemed to be seeing about 18 arcseconds peak-peak error when unguided in RA. The good folks at Meade wondered about that because their preshipment tests on my mount were better than that so I now have a “loaner” RA assembly to install and try. Fortunately, the mount is very modular so it’ll be an uncomplicated swap once the mount is unloaded and the c/w shaft removed; I’m just waiting for weather and time to get that done. I’ll need to open the roof to remove the OTA so it can’t be raining and I’ll need to see what I’m doing so it can’t be dark. Given the weight of the OTA and the counterweights, it’ll probably require a relative humidity of less than the 80% it has been here (that’s real work for an over-60 guy in hot weather). I’ll report on that project and any performance difference I see afterwards.

note: I relocated the Starlock to the top of the OTA to compensate for tube-ring-related flexure after posting the last image so I haven’t seen what difference that made. If possible, I’ll try to grab one image with that configuration before making the RA change in an attempt to isolate the effects. It shouldn’t affect true PE at all; just RA drift.

For anyone who doesn’t want to bother going through all the earlier posts in search of information: all images posted here were captured using an AT12RC at 2400mm focal length and a QSI683WSG-8 with 5.4 micron pixels. Some of the images are binned to double that size. All were guided with Starlock using the autoset parameters. Polar alignment was done using the mount’s assisted drift alignment routine. Mount control is via TheSky6, using the LX200GPS drivers and the mount’s HPP/Starlock autocentering. Capture and calibration software is Maxim/DL, alignment, noise reduction, and combination are done with CCDStack2, and final processing with Photoshop CS. My last mount was a Takahashi NJP. All images were captured from my red zone location: http://cleardarksky.com/lp/UrbnObOHlp.html?Mn=astronomy .

Finally had a decent weekend night here. No Moon, decent seeing, unusually good transparency. Grabbed NGC5907 and M101. M101 has always been a challenging object for me; the images always appear “flat” when captured from my urban location. I spent more time than usual gathering data on this relatively dim extended object, hoping that the combination of more exposure time and lower-than-usual skyglow will make a difference. We’ll see what I get when I process that one. The other galaxy is a new target for me and I think it came out nicely.

 

The mount appeared to perform well. No wind and no discarded frames in several hours of steady work. It would have been a good night for some data gathering but I wanted to enjoy the unusually good conditions rather than doing work. Next time there’s decent seeing but a full Moon I’ll do it.

Things didn’t look great at the start, but after the 20mph gusts died down the guiding settled down nicely so I stayed up and started over. It’s 3:00am local time and I have to be in the office later this morning so I’ll add to this post tomorrow. Just wanted to get the image up right away.

lrgb-7-1000

Had big plans this weekend; the Clear Sky Chart claimed I’d have my first two clear weekend nights since the mount was delivered. M57 is a challenge object on CN this month so I figured I’d grab some LRGB plus some ten minute  Ha and OIII exposures and put together something nice. Waited a couple of hours Friday night but it never cleared. Sat in the observatory for an hour Saturday night waiting for light, fast-moving clouds to pass, then started a long series. Clouds came back; I left the series running in case it cleared but that never really happened. Got a few L, R, G, B frames and a couple of Ha but that was it. I am accustomed to getting by with less data than most folks like to use, but with only three or four each LRGB frames things are gonna be noisy. Only got two Ha frames; also inadequate. I never tried to stack only two frames before – CCDStack2 did that surprisingly well but it wasn’t very smooth.  The original plan was to shoot 1X1 and crop to make a large M57 image. When I saw the clouds I switched to 2X2 for shorter exposures so no cropping.

M51LRGB-5-1000

 

Clear sky, light wind, good transparency, and no Moon. If it were a weekend I’d have gotten a lot done tonight. As it is, I have to be in the office tomorrow morning and I’ve already stayed up too late. Checked the seeing just before I shut down and my urban surroundings (plenty of asphalt, concrete, brick, etc.) were still dumping lots of heat. Translates to big stars (FWHM around 3 arcseconds) in long exposures and dancing stars in short exposures.  No use trying to record tracking errors with the centroid moving around on its own but I can image if I can live with fat stars and some funky star shapes. I gave Starlock a star below 30 degrees declination this time (the handbox warns if using one farther from the celestial equator but I’ve been ignoring it) and let it set up the guide rates (ended up 16 and 10) and then cleared PEC and trained it and added one update run. Chose M51 as a target because it’s near zenith (reduced seeing effects) and because it is in a star-poor region; I wanted to see if Starlock could find something on which to guide. It did, and seemed to work well.

Talked to the guys at Meade today and was told not to read too much into the recorded pec data; I’ll have to wait for good skies to evaluate tracking. I might still be within the 10 arcsecond p-p some are reporting.

 

SO – here’s what I got tonight in about 90 minutes of shooting LRGB. Larger version is at http://www.cloudynights.com/photopost/showphoto.php?photo=27559&size=big

-edit- Fixed the star shapes; shouldn’t try to stack images at 3:00am! Accidentally left the blue frames unselected when aligning in CCDStack2. Fixing that made the stars round plus improved detail generally.

M13RGB-2-1000First, a little news. Meade has issued firmware updates for both the mount and the Starlock module, and also an updated version of the PEC editor. My router still blocks only one site (Meade) so I had to download it all at the office and drag it home. Eventually I’ll make fixing that a priority. All installed, all working fine. Bigger news is that JOC (Meade’s primary supplier of imported products for many years) proposes to buy control. The stockholders should surely approve this; it would result in a serious cash injection for Meade and ensure their survival for quite a while.

 

I used the PEC editor to look at the PEC data stored in the mount. It’s a little disappointing; looks like maybe 16 p-p arcseconds uncorrected PE. I’ll call Meade about that at some point. PPEC and Starlock seem to be managing that pretty well, though.

 

Meanwhile, another quickie test image shot through cloud openings. The Moon was up for the later exposures so had to do some equalization to keep the stars above the background light. CCDStack2 is an excellent program that handles that very well. Only 100 second exposures because I had to get some data before the clouds took over completely.
