  1. Thanks very much fellas!
  2. Thanks for the comment!
  3. Gassendi - After some atrocious weather on the night of the 24th the weather cleared up and the atmosphere and seeing seemed repetitively stable. As with my other lunar nemesis Archimedes, i've never had great enough seeing or timing to capture it with any decency. Though still it defeats me, this Gassendi i'm half pleased with. Gassendi is a large lunar crater feature located at the northern edge of Mare Humorum. The formation has been inundated by lava during the formation of the mare, so only the rim and the multiple central peaks remain above the surface. The outer rim is worn and eroded, although it retains a generally circular form. A smaller crater Gassendi A intrudes into the northern rim, and joins a rough uplift at the northwest part of the floor. The crater pair bears a curious resemblance to a diamond ring. In the southern part of the crater floor is a semi-circular ridge-like formation that is concentric with the outer rim. It is in the southern part where the rim dips down to its lowest portion, and a gap appears at the most southern point. The rim varies in height from as little as 200 meters to as high as 2.5 kilometers above the surface. The floor has numerous hummocks and rough spots. There is also a system of rilles that criss-cross the floor, named the Rimae Gassendi. C11/ASI120MM/Red Filter Astrobin full version: http://www.astrobin.com/222220/
  4. Thank you ver much, all of you. It's a challenging target but sometimes you just get lucky!
  5. I focus by hand and nothing else believe it or not! I don't have an auto focuser - all by the focus wheel =) Nope not guiding or tracking unless you could the NEQ6 tracking computer only!
  6. Hi steve, about 25f/l with a 2.5x powermate!
  7. Hello Kokatha - thanks for the compliment! In the second image there is also, from what i can see, a large mass on the south polar region (especially seen in the astrobin version). An interesting feature.
  8. Hi guys, it's been a while since i've been active here but i thought i'd share some of my recent lunar images from the last 6 months or so in a small collection of pictures! All images taken with a C11 - ASI120MM (mono) and astronomik red filters usually red.
  9. I've not posted here in quite a white but decided to place some recent images up; here one of Uranus at opposition. Uranus is a bit of a beast to image and requires patience and good seeing. Luckily i was able to keep both for my imaging run! 3 images taken over the period of about 3 hours between sporadic clouds. Bright polar quite visible in the first two runs, washed out by worsening seeing in the early hours of the 15th in the 3rd image.C11/ASI120MM/IR685nm.http://www.astrobin.com/full/220109/0/
  10. Thanks very much, guys. This is my first ever really good +F/20 image of a crater so i am very pleased.
  11. Langrenus at sunset The the night of 9th of October saw some very good seeing and i was able to capture some very pleasing results. This is langrenus and it is a prominent impact crater located near the eastern lunar limb. The feature is circular in shape, but appears oblong due to foreshortening. It lies on the eastern shore of the Mare Fecunditatis. To the south is the overlapping crater pair Vendelinus and the smaller Lamé. More to come for this evening of imaging soon.

  12. And now one of mine, Bryan! It's a very interesting region and one i'll be exploring more in the waxing moon, especially Gylden Valley.
  13. Getting your scope cooled and collimated is extremely important - a 'warm' telescope is nearly as bad as bad seeing in my view. Goodluck!
  14. Kokatha, i used the resizing to 200X in Registax and yes it lost loads of contrast for some reason!
  15. Hi. Well the 'crisp and smooth' quality comes with three things that aren't necessarily to do with the filter or processing. Firstly having the lunar surface with good seeing is always a must, then having a fully cooled down telescope - mine often takes an hour and a half to cool down and when it is the difference visually and photographically is astonishing. Getting your telescope fully cooled down to ambient is very important. I see you have a 190mn so it should't take anywhere near the time it takes my closed SCT to cool down. And lastly collimation: The lunar surface is particularly sensitive to miss collimation and i collimate on a regular basis; i collimate at least twice (or at least check). These three things done in combination well will give you the best results possible. In terms of IR filters and processing there really isn't any secret. I ether use a standard Astronomik Typ2 Red or a 685nm filter. There is a great difference between the two and though i use a 685nm currently the 742nm will serve you well also. The IR filter gives you a great deal more contrast and depth compared to the standard red. That said i have had really really good results with a standard red filter so i'm not knocking it. Processing is really simple: i throw it into Auttoskakkart to stack, then into Registax for wavelets then onto PSE for a little more sharpening, cropping and file conversion. Job done! Cheers, Mike.
  16. Cheers Steve. I think the scope needs a little collimation though! =)
  17. Hi Steve. I used the ASI120MM at F/10 with a 685nm IR filter. This was all taken with a C11 SCT.
