An alternative, is to replace the stock fibre gasket with a thin rubber one, this provides some grip between the housing and the corrector to prevent it ...
A few parts, all with low trigger current to drive direct: For the opencollector type at a few ma output, PS2501-4 Relay type: he721a0510/HE101-ND 5V/10ma...
... Just don't forget to consider systems with positive ground (yes, they do exist, even from SBIG) and possibly some mounts whose guider inputs may be pulled...
... It was a great contest this year, the images were simply superb, and you're right Rod, Roth Ritter brings a touch of class and professionalism with his...
Thanks. That is a good idea. The main thing I would like input on is "how long?" I am not sure that this one did not run on for too long a period. What do...
I'm sorry to hear the contest is causing / has caused you stress, Frank. Rest assured that from an observer's point of view it looks like you've got things...
Perhaps we should start the next one! seriously, a contest running all year long (open to photos taken since closing of previous contest deadline) allows all...
... This is probably going to bring some "boos", but in fairness to entrants everywhere I would think a year-long contest would permit everyone to have at...
Hi Everyone...... Thanks to Noel Carboni and the fact that I have his tools:) he sent me a email I have been away from my computer due to a family health...
Spent a few moments with some very knowledgeable SCT users collimating my scope last weekend at Tennessee Spring Star Party. We had it collimated, and a Ronchi...
You're saying the rings were equally spaced, but extincted due to brightness falloff quicker on one side than the other? You didn't by chance have fog starting...
Sorry for the Delay Everyone I personally never thought I would win or place......the images posted by everyone are extraordinary Thanks for the Putting my...
A full year-long contest seems kind of long, though I agree it would be great to be able to open the object list up to the whole sky, as seen in the evening...
John, How many lines per inch was the Ronchi grating? A 50 lpi grating is so un-sensitive that it will make poor optics look bad. A 100-200 lpi grating is much...
... I don't think I had any fog or dew. If memory serves me correct, the rings that match all the way around seemed equal, but yes, there appeared to be a...
... You might consider rotating the season of the contest from one year to the next. that way some years you would have the winter targets, other years the...
No...I don't think so. I believe we need a break and not a never-ending contest--for all concerned. I am considering making it as _short_ as possible, centered...
... Hmmm, OK. How about this idea: a one-month long contest duration for submission of entries and to check rules compliance, etc etc but permit entries to...
... I'm sure Frank D. can comment on that. :-) Even judging took over 3 weeks and I felt like my eyes were about to pop out of my head. ... That's a good idea!...
I think a month is more than enough for people to submit their entries, change their minds, discuss any issue of ineligibility, and - unless they submit at the...
Uncle Rod, Frank, et al, I think alike with this and Thad's post. Pick a year long spread to allow the pictures to be taken based on what is visible when - AND...
I agree with this, and hope to submit for next years contest. Doug ... -- Doug Truckstop Astronomer [Non-text portions of this message have been removed]...
That's basically what I am thinking...allow anything taken between now (the end of the last contest), and the end of the next one. I am thinking, though, maybe...
... Super, just wanted to be sure all bases were covered. :-) By the way, what exactly is it you're building? I don't recall seeing anything mentioned in this...
There you go Uncle Rod! That gets my vote! I'd ACTUALLY get the chance to get the scope out to see more than cloud base or drown as it stands! Bob - N0DGN ......
Hi I agree with you, Rod. A year long window for the images seems right but the 1 month duration seems short. I was thinking maybe 2 months but 3 is probably...
I agree with you Unk Rod. Three months of "actively running contest" is much better than a month (even though one month "will do"). And allow entries taken...
