As Mike and the others have stated I also have to confirm that the tail of T7 mow is less pronounced recently. Even with my 55 min L exposure it is hard to...
Hi Johannes, You have captured about 21 arc minutes of tail even with the bright moon. That is considerably better than I was able to get on Jan 30th with 14 x...
Hello to all.... I thought that you would all be interested in learning a bit more about Mike Holloway, who has provided us with some very fine images of...
Does not the brightness of the moon now almost full have an interaction with the atmosphere so as to dim faint comet tails? Or are you reporting a comet...
Johannes, I think you have captured the ion tail (top) and the shorter but somewhat brighter dust tail (bottom). The ion tail seems to be slight disconnected...
G'day All, For some reason I have become quite interested in capturing images of this comet, probabbly largely because of it's relatively faint brightness (mag...
Impressive animation Roger, considering how faint the comet was. I also enjoyed browsing your website -- nice work. -Mike ... Michael P. Caligiuri, Ph.D. ...
Roger It is always nice to see observations and photos from sites in the southern hemisphere that we can't see here. Nice site but for some reason, I have not ...
I would like to quantify my comet images by photometry. If any of you are doing comet photometry with MaximDL. I'd like some tips on using it. In particular,...

Mike, A suggetion for the Yahoo Group set up. You can set the default display for the calendar to Month, instead of day. Only the Owner or moderator can do...
Mike & Carey, I went ahead and set the calendar option since probably no one was concerned about the setting before anyway. Carey, check the "Files" section....

Eric, Thanks for your reply. That's odd that the animation isn't working for you. It did take me a couple of goes right now, but it did work on the second try....
Most yahoo accounts come with about 30 megs of space in your briefcase or photos that you can put your pictures in. Many images when saved as jpg files should...
Charles is correct. The space is provided for members to use. Some may not have space to publish images and this will give those a place to go. If and when...
Roger Thanks. I just has to wait a bit and the animation started to recycle and show. Nicely done. Meanwhile, I have used the freeware image j software with an...
I might add that if you use the group's file or photo section to post an image, you might want to create folder with your name on it and place your images in...
Just between Moonrise and Sunset, I managed a number of shots. This is a composit of 5x120 sec exp with the 4" and ccd. Tail is strange once again and...
Hi, For all the northerners on the list Q4 is developing nicely, and tonight there was a narrow margin between end of astronomical twilight and moonrise. I...
I imaged T7 between twilight and moonrise but lost precious time focusing and positioning. There is a hint of two tails. I did manage to capture magnitude...
Hi there, Just a quick note to say Hi to everyone. I was recommended to this group by Dennis Persyk, who I know through the LX90 group. My main field of...
Comet is becoming harder to image. The streak from the right (west) side of the image to the comet is the 2nd mag star playing tricks. This star and the lower...

I cut the image time from 120 sec to 60 sec each and doubled the exposures from 5 to 10. It is a shame that our position is not a little better. This image...
Very nice image Mike. I hope to get out this weekend and try this comet with my new 480mm F6 refractor. Can I assume the gradient in the lower right is light...
Thanks. The gradient in this case is caused by bad flatts. I am pretty sure the position of the camera moved so today I will create some new flatts to apply....
